This article describes how to create a SIP helper for custom ports.
Scope
FortiGate 6.x and later.
Solution
If there is a VoIP solution that needs a custom port, and it is desired to use SIP session-helper instead of the recommended SIP-ALG for these sessions, here is an example of how to do it.
Let's take port 6050 for this scenario:
config system session-helper
edit 0
set name sip
set protocol 17
set port 6050
end
Note: In this example, 'edit 0' uses the next available item ID automatically.
It is possible to follow this procedure multiple times if needed.
