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 M?xico S.A. de C.V.

I am still having a very frustrating problem win an Avaya-Asterisk system. I have written about this before but I am expanding the description of the problem just in case someone can give me some insight. This installation is an Asterisk 1.4.19.1 server connected to an Avaya PBX using a PRI E1. Integration works great and we can dial from any extension to any extension on both sides. The problem happens when we connect a Linksys PAP2T outside the network. If I dial an extension on the Avaya from that PAP2T I get one way audio (I can hear them but they cannot hear me). This only happens when I dial an extension on the Avaya. If I dial to the voicemail extension I can get my messages. I can speak to any SIP extension connected to the Asterisk server. Here is the strangest part: If they dial the PAP2T from an Ayava extension everything works great, audio both ways. In this installation there are 45 PAP2T and 45 SPA3102 external extensions. All the SPA3102 extensions do NOT have the problem the PAP2T does. I always get two way audio with the SPA3102. When I do an "rtp debug" I can see that incoming RTP packets stop the moment the Avaya extension picks up. If the PAP2T is connected on the same internal network as the Asterisk then everything works, only when the PAP2T is outside the network do we get one way audio. The only difference I can find between the configuration of the SPA3102 and the PAP2T is a parameter called "Symmetric RTP" which is enabled on the SPA but does not exist on the PAP2T. I do not know if this has anything to do with the problem but there is nothing else I can find. Any recommendations on how to tackle this problem? Right now the only solution I can see is to replace all PAP2T with SPA3102 but obviously I would like to avoid the expense. -- Telecomunicaciones Abiertas de M?xico S.A. de C.V.
