We have an issue where some of our outgoing calls are dropped after 30 - 32 seconds.
I posted in the freePBX forum but didnt get any help.
I have NAT setup on pfSense to forward SIP provider network, SIP ports and RTP ports to the PBX. I have also tried adjusting the settings in freePBX but dont seem to be able to fix the issue definitively.
Does anybody have any other suggestions?
