R2511-HP MSR Router Series Voice Command Reference(V5)

214
Default
The global transport layer protocol is UDP, and no transport layer protocol is specified for a VoIP voice
entity. If the transport layer protocol is not specified for a VoIP voice entity, the global setting is applied.
Views
SIP client view, VoIP voice entity view
Default command level
2: System level
Parameters
udp: Specifies UDP as the transport layer protocol for outgoing SIP calls.
tcp: Specifies TCP as the transport layer protocol for outgoing SIP calls.
tls: Specifies TLS as the transport layer protocol for outgoing SIP calls.
Usage guidelines
The execution of the transport command in SIP client view specifies the global transport layer protocol.
If you want to configure a different transport layer protocol for an individual call, you can specify the
transport layer protocol to be used in corresponding VoIP voice entity view. When the transport layer
protocol configured in VoIP voice entity view and that configured in SIP client view are different, the
former is adopted. The VoIP voice entity configuration takes precedence over global configuration.
This command is effective only when the type of the VoIP voice entity is SIP.
The transport layer protocol configured on two communication parties must be the same. If you execute
the transport tcp command on the sender device, you must execute the listen transport tcp command on
the receiver device.
Before specifying TLS as the transport layer protocol, you need to configure the SSL policy names of the
client and the server with the crypto command. Otherwise, no session request can be initiated.
Examples
# Specify TLS as the transport layer protocol for outgoing SIP calls.
<Sysname> system-view
[Sysname] voice-setup
[Sysname-voice] sip

to send request messages.
Use undo uri to remove the user information.
Syntax

Default
Number@SIP-device-domain-name or number @SIP-interface-IP-address is used to send request
