[Asterisk-Users] Connections, but no voice paths except by console

[Moshe Yudkowsky]

Steven,

As per your advice, I have tried to not load the console -- which in this 
case, if I understand correctly, would be the chan_alsa.so and chan_oss.so 
modules.

* I never load chan_alsa.so, because chan_alsa doesn't work for me and I 
haven't figured out what the problem is just yet.

* If I unload chan_oss.so from a running system, I crash on the first call. 
The system shouldn't do that, I expect.

* If I noload chan_oss.so, then I can call from a softphone to, e.g., 
voicemail -- but again I cannot transmit audio, only hear it on the softphone.

A softphone call from the PC to voicemail connects, but cannot transmit or 
receive audio.

I will guess that I'm missing something obvious -- that the console is some 
other application?
