Chapter 22 VoIP Solutions: SIP : FortiGate VoIP solutions: SIP : The SIP session helper : SIP session helper configuration overview : Changing the port numbers that the SIP session helper listens on
  
Changing the port numbers that the SIP session helper listens on
You can use the following command to change the port number that the SIP session helper listens on for SIP traffic to 5064. The SIP session helper listens on the same port number for UDP and TCP SIP sessions. In this example, the SIP session helper is session helper 13:
config system session-helper
edit 13
set port 5064
end
 
The config system settings options sip-tcp-port, sip-udp-port, and sip-ssl-port control the ports that the SIP ALG listens on for SIP sessions. See “Changing the port numbers that the SIP ALG listens on”.
Your FortiGate unit may use a different session helper number for SIP. Enter the following command to view the session helpers:
show system session-helper
.
.
.
edit 13
set name sip
set port 5060
set protocol 17
end
