Configuring UDP or TCP for outgoing SIP calls

The execution of the transport command in SIP client view specifies the global transport layer protocol for

outgoing SIP calls. If you want to configure a different transport layer protocol for individual calls, you

can specify the transport layer protocol in corresponding VoIP voice entity view. If the transport layer

protocol configured in VoIP voice entity view and that configured in SIP client view are different, the

former is adopted.

Configuration prerequisites

If a SIP server is used to forward calls, you need to complete the configurations on the SIP server.

Configuration procedure

To specify UDP or TCP as the global transport layer protocol for outgoing SIP calls:

Step Command Remarks

1. Enter system view.

system-view N/A

2. Enter voice view.

voice-setup N/A

3. Enter SIP client view.

sip N/A

4. Specify UDP or TCP as the

global transport layer

protocol for outgoing SIP

calls.

transport { tcp | udp } By default, UDP is adopted.

To specify UDP or TCP as the transport layer protocol for outgoing SIP calls on a VoIP voice entity:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Enter voice view.

voice-setup N/A

3. Enter voice dial program

view.

dial-program N/A

4. Enter VoIP voice entity view.

entity entity-number voip N/A

5. Specify UDP or TCP as the

transport layer protocol for

outgoing SIP calls.

transport { tcp | udp }

By 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.

This command is effective only

when the type of the VoIP voice

entity is SIP.

NOTE:

The transport layer protocol configured on two communication parties must be the same. That is, if you

execute the transport tcp command on the sender device, you need to execute the listen transport tcp

command on the receiver device.

To set the aging time for TCP connections:
