Choose a trunk transport protocol
Genesys Cloud supports three trunk transport protocols for use with BYOC Cloud. When you configure your BYOC Cloud trunk and select either BYOC Carrier and BYOC PBX as the trunk type, you can select UDP, TCP, or TLS as the trunk transport protocol.
|Trunk transport protocol||Description|
|UDP||UDP (User Datagram Protocol) is the standard trunk transport protocol. It provides fast, low-latency connections as it uses a continuous packet stream without acknowledge packets (ACK).|
|TCP||If you include large amounts of UUI or custom data in your headers, choose TCP as your trunk transport protocol. Doing so prevents call failures when packets exceed the maximum transmission unit (MTU) of the standard UDP trunk transport protocol.|
|TLS||To ensure that your transactions are secure, choose TLS (Transport Layer Security) as your trunk transport protocol. For more information, see TLS trunk transport protocol specification.|
Warning: When you choose a trunk transport protocol, it is important that you configure both ends of the trunk to use the same protocol. If they are not using the same protocol, the trunk fails to function.
