I have installed asterisk with an ATA 186 on my notebook computer. The notebook computer has a not working sound card, but everything worked fine.<BR>
<BR>
I moved everything to my main server which is outside my NAT firewall and re-set the ATA 186 to work with it. The main server does not have a sound card [I think].<BR>
<BR>
I can connect and I can make calls but hear nothing and the echo-back test fails. <BR>
<BR>
This is what I see on the console:<BR>
<BR>
NOTICE[5126]: File chan_sip.c, Line 1722 (process_sdp): Content is 'application/251', not 'application/sdp'<BR>

<BR>
Hope someone understands the problems.<BR>
<BR>
I have tried various combinations of <BR>
<BR>
noload => chan_alsa.so<BR>
load => chan_oss.so<BR>
<BR>
in the modules.conf<BR>
