SIP/RTP issue - FortiGate 100E
I was wondering if anyone may be able to assist with an ongoing issue I'm experiencing with a client. The client has an internal PBX system and a SIP trunk from a third party which originally had issues with inbound RTP working.
I've gone ahead and managed to rectify the problem with inbound RTP not working and audio now works both ways, although it seems the call cuts off around 5 minutes, 33 seconds each time. This issue seems to have only started since the new FortiGate 100E was installed.
The changes I've made were the following:
config system settings
set sip-helper disable
set sip-nat-trace disable
set default-voip-alg-mode kernel-helper based
config system session-helper
delete 12 (this was the voip rule)
config voip profile
set rtp disable
diagnose sys session clear
Any assistance would be much appreciated.
