I have a big headache. I have an Asterisk server connected to an Avaya PBX. Everything is working between those two. The problem is that I have 45 PAP2T adapters and 45 SPA3102 adapters that connect via the Internet to the Asterisk server through a Fortinet firewall. When calling from a PAP2T I get one way audio, the remote site can hear me but I cannot hear them. If I do an "rtp debug" I can see rtp going out but none coming in. The even stranger part is that the SPA3102 works fine.
Why would two similar adapters behave differently? I cannot think of any setting on the PAP2T that is different from the SPA. If I connect the PAP2T on the same network as the Asterisk server then audio is fine, the moment it crosses through the firewall we only get one way audio. Anyone had a similar experience? -- Telecomunicaciones Abiertas de México S.A. de C.V. Carlos Chávez Prats Director de Tecnología +52-55-91169161 ext 2001
