Trunk reference
Trunks facilitate point-to-point communication. All of the Edges in an Edge group can share trunks.
Trunk types include WebRTC, SIP carriers, VoIP, Mobile, SMS, or proxy servers and each type of trunk has its own unique configuration requirements.
The following tables summarizes the characteristics of trunks used in the Genesys Cloud environment.
| Typical call syntax | Server proxy list | Features |
|---|---|---|
| 911 3172222222 19196669800 |
Yes, typically one entry. 162.97.105.13 |
Usually requires an interface route for indirect routing to a local intermediary. Example: route add 162.97.105.8/27 172.18.184.10 -p Trunks can be special purpose to handle only certain classifications of calls (Emergency, Local, Long Distance, International) or they can handle a mix including all. |
| Typical call syntax | Server proxy list | Features |
|---|---|---|
| 911 3172222222 tel:19196669800 sip:+19196669800@10.0.0.90; user=phone |
Yes, typically one or more of the gateway(s). 10.0.0.90 |
If the interface is directly attached to the same network, the system does not require a route. Gateways typically only handle tel: addresses but can be referenced directly by sip addresses. Some gateways do not accept tel: addresses directly and require sip: addresses. Gateways host multiple TDM Trunks and can be special purpose to handle only certain classifications of calls (Emergency, Local, Long Distance, International) or they can handle a mix including all. |
| Typical call syntax | Server proxy list | Features |
|---|---|---|
| 13177158206 sip:2222222@indyhqic sip:8206@indyhqic |
Yes, typically two: a primary and a backup. 172.17.250.243 172.17.250.244 |
If the interface is directly attached to same network, the system does not require a route. |
| Typical call syntax | Server proxy list | Features |
|---|---|---|
| 2222222@10.0.0.90 sip:joe.smith@rtpedge1.genesys.com sip:105@indyhqic.genesys.com 8206@indyhqic sip:+13178723000@indyhqic1 |
No | Able to route to any device on the network. |
| Typical call syntax | Server proxy list | Features |
|---|---|---|
| Anything. A proxy can front any of the other trunks. | Yes, typically one or more of the proxies. Primary plus failovers. 10.10.254.18 |
Web Admin, for example: https://10.10.254.18:442 Proxies are intermediaries and forward on requests without modifying them much. They do not necessarily stay in the route after connect. |
| Typical call syntax | Server proxy list | Features |
|---|---|---|
| Anything. An SBC (Session Border Controller) can front another network. | Yes, typically one or more of the SBCs. | SBCs are on the edge of a network and handle ingress and egress traffic. They act as a B2BUA (Back-to-Back-User Agent) always modifying/hiding the request. They always stay in the route. Example: Third parties, such as Acme Packet. |
