I have been extensively testing VOiP with and without the ASG VOiP security.
Without VOiP security enabled, only using PF rules VOiP works.
With VOiP security enabled
1/. I can make the calls,
2/. I hear the ring
3/. I can hear sounds from the far end,
4/. but I am not heard at the far end.
5/. The PF log shows the incoming traffic at setup time blocked, but shows lots of outgoing packets.
Setup is
phone -> pap2t -> ASG-> mynetfone (VOiP provider)
ASG setup with PF rule pap2t rtp mynetfone allow
My VOiP provider has two sip proxies, but both resolve to the same IP address, but my packets are sent (x.x.x.24) to one IP address and answered by another (x.x.x.20). I have allowed for this by the use of network groups within mynetfone definition.
Any help would be gratefully appreciated.
