I recently reinstalled our Asterisk (22.214.171.124) test machine (Ubutnu Jaunty) on the office LAN. Everything appears fine, except I get no audio from it. It is receiving DTMF tones fine.
Playback() seems to be doing something, but a tcpdump on the host shows audio only from my handset to Asterisk, nothing from Asterisk’s playback() however.
We have a second asterisk installation and that one is working fine. We are baffelled! Both are behind the same NAT/firewall and connect to Gradwell using IAX2. The test box has Asterisk/Dahdi_dummy built from source.
Must be something simple but I really need some suggestions… Thanks!
