External trunk settings - Genesys Cloud Resource Center

There are three types of external trunks: BYOC Carrier and BYOC PBX (for BYOC Cloud), and External SIP for (BYOC Premises). When you configure an external trunk, you configure the basic settings described in the Create a trunk under BYOC Cloud and Create a trunk under BYOC Premises articles. Depending on your needs, you may also configure some of the more advanced settings. This reference describes all the settings that you find on the Create/Edit External Trunk page.

Note: While most of these settings apply to all types of external trunks, some settings apply only to certain types of trunks. Those settings that are trunk type specific are noted in the description.

Setting	Description
External Trunk Name	Use this box to assign the external trunk a descriptive name. This name identifies this trunk when you need to select an external trunk on the various telephony configuration pages in Genesys Cloud.
Type	Use this list to select the type of external trunk that you want to create. There are three choices: BYOC Carrier BYOC PBX External SIP For more information on creating trunks, see Create a trunk under BYOC Cloud and Create a trunk under BYOC Premises.
Type	BYOC Carrier and BYOC PBX only When you select one of the BYOC trunks, you see a second Type list. If you select the BYOC Carrier trunk, you need to select the type of carrier you want to use. You can select either Generic BYOC Carrier or Verizon BYOC Carrier If you select the BYOC PBX trunk, you need to select the type of PBX you want to use. you can select Generic BYOC PBX.
Managed By	Use this switch to specify who is authorized to manage the External Trunk configuration going forward. The default setting is Everyone, which includes telephony admins and the provider. However, you can select the Provider Only option to limit control to just the provider.
Trunk State	Use this switch to change the operational state of the external trunk. The default setting is In-Service.
Protocol	Use this list to choose the trunk transport protocol variant. There are three choices for the trunk transport protocol: UDP TCP TLS In most cases, you select UDP as the Protocol.
Listen Port	External SIP only Use this box to specify the trunk transport listen port. Common values for this setting in Genesys Cloud are 5061 for TLS and 5060 for UDP and TCP.

Common values for this setting in Genesys Cloud are 5061 for TLS and 5060 for UDP and TCP.

Inbound

Setting	Description
Number Plan Site	Use this setting to identify the site with the number plan that you want to use. To improve inbound call handling, Genesys Cloud allows you to identify the site with the number plan that you want to use. The site that you select controls which number plan is used, both for transforms on inbound calls and for subsequent outbound transfers for calls that never flow through another site.
Inbound SIP Termination Identifier	BYOC Carrier and BYOC PBX Use this box to specify your termination identifier. Genesys Cloud requires that a unique identifier exists in the INVITE to associate inbound calls with the appropriate Genesys Cloud organization’s resources. By default you can use the FQDN or the TGRP method for formatting your SIP INVITES. To make it easy to understand how to format inbound INVITES, the user interface provides dynamic help. When you begin typing an identifier in the Inbound SIP Termination Identifier box, the Inbound Request-URI Reference panel appears. This panel provides you with invite formatting examples that include your termination identifier and the address of your Genesys Cloud organization’s region. If you select Generic BYOC Carrier, the Inbound SIP Termination Identifier is a static configuration that should be populated with a regionally unique identifier. This identifier will be used to direct traffic from external Carriers to the organization. If you select Verizon BYOC Carrier, the Inbound SIP Termination Identifier is a static configuration that should be populated with a regionally unique identifier. This identifier will be used to direct traffic from Verizon to the organization. If you select Generic BYOC PBX, the Inbound SIP Termination Identifier is a static configuration that should be populated with a regionally unique identifier. This identifier will be used to direct traffic from third-party PBXs to the organization.
Inbound SIP Termination Header	BYOC Carrier and BYOC PBX Use this box to specify the name of the SIP header the carrier will populate with the inbound SIP termination identifier value on inbound calls. You only use this setting when none of the standard identification methods are supported by your carrier. If you select Generic BYOC Carrier, the Inbound SIP Termination Header is a custom field that contains the Termination Identifier value for inbound calls to Genesys Cloud. If you select Verizon BYOC Carrier, the Inbound SIP Termination Header is by default set to X-VZ-CSP-Customer-Identifier. If you select Generic BYOC PBX, the Inbound SIP Termination Header is a custom field that contains the Termination Identifier value for inbound calls to Genesys Cloud.
DNIS Replacement Routing	BYOC Carrier and BYOC PBX If your carrier’s requirements prevent you from using either the FQDN or the TGRP method for formatting your SIP INVITES, you can enable DNIS Replacement Routing. You can then format your SIP INVITES using the DNIS method. The same dynamic help is available.
For more information, see Configure SIP routing for a BYOC Cloud trunk.

^* To make it easy to understand how to format outbound INVITES, the user interface provides dynamic help. When you begin typing an identifier in one of the outbound SIP boxes, the Outbound Request-URI Reference panel appears. This panel provides you with invite formatting examples that include your termination identifier. For more information, see Configure SIP routing for a BYOC Cloud trunk.
SIP Servers or Proxies	Use the controls in this section to create a prioritized list of SIP servers or intermediate proxies to which all outgoing requests should be sent regardless of the destination address in the request. You can also add a port number. If do not specify a port number, the inbound listen port is used by default. Note: When adding multiple SIP servers or intermediate proxies, make sure you order the list with the highest priority at the top. External SIP only IP addresses added to the Outbound SIP Servers or Proxies section are placed automatically on the SIP Access Control Allow list.
Digest Authentication	Use this switch to enable or disable Digest Authentication. When enabled, digest authentication provides extra layer of security to the process of granting outbound requests. If you enable digest authentication, you need to specify the associated realm, the user name, and password to use as the authentication credentials. The default setting is Disabled.
Realm	Use this box to specify the domain name of the SIP realm that authenticates outbound requests.
User Name	Use this box to specify the user name to use to authenticate the call.

Calls

Setting	Description
Max Calls	External SIP only Enter a value in this box to either limit or expand the maximum number of combined active inbound and outbound calls that are allowed on this trunk. Notes: On an external trunk, the Max Calls setting is a per trunk setting. Max Calls is the amount of calls the trunk on a particular Edge can handle. Setting Max Calls to 0 (zero) will configure the trunk to accept an unlimited number of calls. If you set Max Calls to 0 (zero), be sure to take into account the concurrent call capacity for your Edges. Setting the Max Calls to 0 (zero) does not increase the Edge’s concurrent call capacity. For more information, see Concurrent call capacity for Edge models. For more information, see Configure maximum call settings.
Max Concurrent Calls	BYOC Carrier and BYOC PBX Select an option to either limit or expand the maximum number of combined active inbound and outbound calls that are allowed on this trunk. The default setting is Unlimited. Genesys has optimized the Max Concurrent Calls setting to be set to Unlimited. As such, Genesys recommends leaving the Max Concurrent Calls set to Unlimited. However, if you or your carrier determine that setting a limit on the number of concurrent calls is required, then you should select Limited to and enter a value in the box. When selecting the Limited option, Genesys recommends that you carefully evaluate the number of calls that you want to be able to handle concurrently. For more information, see Configure maximum call settings.
Max Call Rate	Use this box to specify the average number of inbound and outbound calls (call arrival/initiation) that can be handled by this trunk per time period. You can specify this number as a decimal or a fraction. For example: 40/5s: This would specify that a maximum of 40 calls can be handled by this trunk every 5 seconds.
Max Dial Timeout	Use this box to specify the maximum number of seconds for a delay before an outgoing call attempt is aborted.
Max Calls Reason Code	Use this box to specify a custom SIP response code that you want the trunk to return when Max Call threshold is exceeded. By default, a trunk returns a 503 Service Unavailable reason code if the Max Call threshold is exceeded. Using the Max Calls Reason Code setting. you can set the reason code to any SIP response code in the 4xx, 5xx, or 6xx range. This allows you to configure a response code, such as 486 Busy Here, that more accurately indicates that the Max Call threshold has been exceeded.

Transport

Setting	Description
Transport DSCP Value	External SIP only Use this list to choose the Differentiated Services Code Point (DSCP) value of Quality of Service (QoS) for RTP and RTCP packets. The system places this value in the upper 6 bits of the TOS (Type Of Service) field. The TOS field is in the IP header of every RTP and RTCP packet. The range of values available is 00 (0,000000) through 3F (63, 111111). The default value is 18 (24,011000) CS3.
	When an outbound call made on this line fails, the trunk receives a Failure SIP Response, which contains either a SIP reason code, a Q.850 cause code, or both. Genesys Cloud compares the codes found in the Failure SIP Response against the codes you configure and determines how to proceed. If the Failure SIP Response has only a reason code and that code matches an item in the Retryable Reason Code list on your trunk, the call will be retried on the next trunk, if there is one. If the Failure SIP Response has a reason code and a cause code and those codes match items in both the Retryable Reason Code and Retryable Cause Code list on your Trunk, the call will be retried on the next trunk, if there is one. If the Failure SIP Response has a reason code and a cause code and neither of them match the Retryable Reason Code or Retryable Cause Code list on your trunk, the call is terminated.
Retryable Reason Codes	External SIP only Use the box to enter a list of valid SIP reason codes. You can specify individual reason codes or ranges of reason codes, separated by commas. By default, Genesys Cloud automatically enters a list of the most common retryable codes in the Retryable Reason Codes field. The default code list: 500–599

Setting	Description
Address Transformation	Use the controls in this section to enter regular expressions and build an ordered list of regular expressions to match and format addresses. The expressions will be applied in the order in the list. If the address matches the match expression, the format expression will be applied. You can add up to three entries to the list. Note: As you fill in the fields in the Called section, keep in mind that the Called address is the number that was called and that it only applies to outbound calls. For more information, see Transform outbound addresses with regular expressions.
Match Regular Expression	Use this box to enter the match regular expression – the pattern that you want to search for in the external trunk number.
Format Regular Expression	Use this box to enter the format regular expression – the format that you want to use to display the result.
Address Digits Length	Use this box to specify the number of trailing digits from the outgoing destination address that is to be sent.
Address Omit + Prefix	Use this switch to enable or disable the ability to exclude the plus (+) prefix in the outgoing destination address that is to be sent. The default setting is Enabled.
Asserted Identity	Select the Send asserted identity header check box to enable sending of the asserted identity header on outbound calls. Enabling this will allow you to choose what information will be placed in the asserted identity header of every call made from this trunk. Under Get asserted identity header from, you can choose to set the asserted identity header or dynamically. Selecting Caller address sets the asserted identity header dynamically. This setting uses the name and address of the originating calling party in the asserted identity header. Selecting Custom data sets the asserted identity header statically. This setting will pull the data from the Caller Address and Caller Name in the Outbound – Calling section, insert it into and Name and URI boxes, and then use it in the asserted identity header.

Media

Setting	Description
DSCP Value	External SIP only Use this list to choose the Differentiated Services Code Point (DSCP) value of Quality of Service (QoS) for RTP and RTCP packets. The system places this value in the upper 6 bits of the TOS (Type Of Service) field. The TOS field is in the IP header of every RTP and RTCP packet. The range of values available is 00 (0,000000) through 3F (63, 111111). The default value is 2E (46 101110) EF.
Media Method	Use this list to choose the method that you want to use to offer an SDP (Session Description Protocol) to the other participant when making an outgoing call. The offer proposes the set of media streams and codecs along with the IP addresses and ports to use. There are three choices for the Media Method: Normal: Use the normal method, which sends an SDP Offer in the initial SIP INVITE request. Delayed: Use the delayed method, which waits for an SDP Offer in a response before sending an SDP Answer. Auto: Allow the system to choose between using the normal or the delayed method.
Preferred Codec List	Use the controls in this section to choose and build a preferred list of codecs. Available choices are: audio/g722 audio/g729 audio/PCMA (g711 A-Law) audio/PCMU (g711 µ-Law) audio/opus Note: PCMU and PCMA are also known as the g711 codec (the PCM stands for Pulse Code Modulation). PCMU (µ-Law) is primarily for use in North America and PCMA (A-Law) is primarily for use in other countries outside North America.
SRTP Cipher Suite List	Use the controls in this section to choose and build a preferred list of SRTP cipher suites to offer or allow in response. Available choices are: AES_CM_128_HMAC_SHA1_32 AES_CM_128_HMAC_SHA1_80 AES_CM_192_HMAC_SHA1_32 AES_CM_192_HMAC_SHA1_80 AES_CM_256_HMAC_SHA1_32 AES_CM_256_HMAC_SHA1_80
Ringback	Use this switch to enable or disable the line ringback. When enabled, this setting controls if a ringback should be generated and sent to the incoming trunk when a 18x response message that does not include an SDP is received\relayed from the outbound call. The default setting is Enabled.
Disconnect on Idle RTP	Use this switch to enable or disable the ability to disconnect a call when RTP is not received for an extended period of time. Note: An extended period of time is defined as 5 minutes for normal calls or 12 hours for media that is sent in one direction (not send and receive). The default setting is Enabled.

UUI is used to send small amounts of data along with call information between applications by embedding that data inside the SIP header. UUI data can be received and sent by Architect and Scripter on call flows. For more information, see Set UUI Data action. The default setting is Disabled. Note: When enabling UUI Passthrough, keep in mind that there is no added security for the UUI data. As such, any sensitive data that could be transmitted via UUI should be encrypted at the client.
Header: Type	Use this list to choose the type of UUI header information you want to use. There are three choices: x-UserToUser: This is the AudioCodes proprietary header, which only includes the data. It does not use the protocol discriminator nor any of the other standard parameters and depending on the encoding you select, it is in the format: `x-User-to-User: hexdata` `x-User-to-User: ascii` User-To-User: This is the general header, which requires the use of the protocol discriminator in the format: `User-to-User: XXhexdata;encoding=hex;purpose=isdn-uui;content=isdn-uui` where XX is the protocol discriminator. User-To-User PD Attribute: This is the type that some gateways use where the protocol discriminator is specified separately in the format: `User-to-User: hexdata;pd=XX;encoding=hex;purpose=isdn-uui;content=isdn-uui` where XX is the protocol discriminator.
Header: Encoding Format	Use this list to select the encoding format for the header. There are two choices: hex ascii Note: If you do not specify an encoding format, Genesys Cloud assumes the Hex encoding format.

Static User Data

Setting Description

Setting	Description
Static UUI	Use the Static UUI switch to enable or disable support for sending static UUI data. When you are sending UUI data with outgoing calls, you usually specify the UUI data in either Architect or Scripter. Specifying UUI data in that manner is the dynamic method. However, if you want to send the exact same UUI data with every outgoing call (static method), you can enable the Static User Data setting. You then specify the static UUI data in the following fields. The default setting is Disabled.
Header: Name	Use this box to specify a name for the header. You can use a name that is the same as one of the standard header type names (X-UserToUser, User-to-User, or User-to-User PD Attribute) or you can specify a custom name for the header. If you specify both dynamic UUI data and static UUI data and each have different header names, Genesys Cloud sends both the dynamic and static UUI data in the outgoing call. Note: If you use one of the standard header type names, the descriptions/rules listed above in the User to User Information (UUI) \| Header: Type section applies.
Header: Value	Use this box to specify the UUI data to place in the header using the appropriate format. For example: `00TestData;encoding=ascii;purpose=isdn;content=isdn-uui` Note: If you specify User-To-User as the header name, you must manually prepend the two characters to the value to act as the protocol discriminator.
Header: Priority	Use this list to specify a priority level for choosing the UUI data source. If you enable the Enable Static User Data setting but may also specify UUI data in either Architect or Scripter, and the UUI data from both has the same header name, Genesys Cloud determines which UUI data value to send based on the Priority setting. If you select Low Priority, Genesys Cloud always chooses the dynamic UUI data from Architect or Scripter. If you select High Priority, Genesys Cloud always chooses the static UUI data you specify here. Note: If you select Low Priority and no dynamic UUI data is specified, then both the empty dynamic UUI data and the static UUI data is sent.

Static UUI

Use the Static UUI switch to enable or disable support for sending static UUI data.

When you are sending UUI data with outgoing calls, you usually specify the UUI data in either Architect or Scripter. Specifying UUI data in that manner is the dynamic method.

Header: Name

Use this box to specify a name for the header.

You can use a name that is the same as one of the standard header type names (X-UserToUser, User-to-User, or User-to-User PD Attribute) or you can specify a custom name for the header.

If you specify both dynamic UUI data and static UUI data and each have different header names, Genesys Cloud sends both the dynamic and static UUI data in the outgoing call.

Note: If you use one of the standard header type names, the descriptions/rules listed above in the User to User Information (UUI) | Header: Type section applies.

Header: Value

Use this box to specify the UUI data to place in the header using the appropriate format.

For example:

00TestData;encoding=ascii;purpose=isdn;content=isdn-uui

Note: If you specify User-To-User as the header name, you must manually prepend the two characters to the value to act as the protocol discriminator.

Header: Priority

Use this list to specify a priority level for choosing the UUI data source.

If you enable the Enable Static User Data setting but may also specify UUI data in either Architect or Scripter, and the UUI data from both has the same header name, Genesys Cloud determines which UUI data value to send based on the Priority setting.

If you select Low Priority, Genesys Cloud always chooses the dynamic UUI data from Architect or Scripter.
If you select High Priority, Genesys Cloud always chooses the static UUI data you specify here.

Note: If you select Low Priority and no dynamic UUI data is specified, then both the empty dynamic UUI data and the static UUI data is sent.

The Protocol Capture setting is enabled while you are working with Genesys Cloud Technical Support personnel. Enabling it generates a PCAP file that contains protocol-specific network information that can be used for diagnostic and troubleshooting purposes. Therefore, you should only enable the Protocol Capture setting as directed by Genesys Cloud Technical Support.

Warnings:

Protocol diagnostics do not capture the following SIP method messages: OPTIONS, REGISTER, SUBSCRIBE, and NOTIFY.
Enabling protocol capture can degrade performance and affect QoS.
Protocol capture logs all data entered into the system, including data entered via Secure IVR flows. This data could include sensitive data that should not be exposed or captured. As such, if your organization is using Secure IVR, you should not enable the Protocol Capture setting.
If you are a PCI-compliant Genesys Cloud organization and have the PCI DSS setting enabled, then you cannot enable protocol capture – the Protocol Capture setting is not available.

For more information, see Enable Protocol Capture.
