R0106-HP MSR Router Series Voice Command Reference(V7)

Usage guidelines
You can configure the transport protocol both globally (in SIP view) and for a specific VoIP entity (in VoIP
entity view). The configuration in VoIP entity view takes precedence over the global configuration. A VoIP
entity uses the global configuration only when no transport protocol is configured in VoIP entity view.
Configure the same transport protocol on the called and calling devices. For example, if you configure
the session transport tcp command on the calling device, you must configure the transport tcp command
on the called device.
You must configure the SSL client and server policies by using the crypto command before you can use
TLS to initiate SIP calls.
Examples
# Specify TLS as the global transport protocol for outgoing SIP calls.
<Sysname> system-view
[Sysname] voice-setup
[Sysname-voice] sip
[Sysname-voice-sip] session transport tcp tls
