I have strange problem installing Asterisk (both 1.0.7 from Debian and 1.2-beta-1 from sources) on my Debian (stable, kernel 184.108.40.206). After installation (including samples), Asterisk starts without problems, SIP phones (X-Lite on Windows and LinPhone on Linux) registers fine, dialing 500 and 1000 demo numbers work - but there is no audio coming back from server, it is completely quiet. On the asterisk console I can see no error messages, just notices about playing the samples.
The strange thing is, everything work perfectly when I unload kernel modules for my TE205P card (using 1.0.9 drivers for Asterisk 1.0.7 and 1.2-beta1 for 1.2-beta1). There are no error messages related to the zaptel drivers, neither on Asterisk console, nor in dmesg.
Exactly same thing happens in both Asterisk 1.0.7 and in 1.2-beta1.
I did no changes to configuration, except for adding clients for the sip phones.
Can anybody please help me? Thanks in advance 8) (I’m sorry if I missed something obvious, but I spent whole day on this problem…)
