Release Information

Statement introduced in Release 10.0 of Junos OS.

Description

Specify the Transport Layer Protocol to be used for the SIP session. You can specify UDP, which carries messages that could be larger than the IP network’s maximum transmission unit (MTU) TCP, which can carry larger messages than UDP and provide reliability and congestion control, or TLS, which provides for secure data delivery at the transport layer..

Options

UDP—User Datagram Protocol. A single UDP packet carries a SIP request or response. SIP messages could be larger than the IP’s MTU size. SIP does not support fragmentation, so UDP SIP messages must be smaller than the MTU size if you use UDP. SIP does not support fragmentation.

TCP—Transport Control Protocol. Because TCP can support messages of arbitrary size, it supports larger messages and provides reliability and congestion control.

TLS—Transport Layer Security, which provides for security and data integrity of communications over the Internet Protocol (IP).
