Hi there,<br>
<br>
I was already writing about this problem, and I still didn't managed to<br>
fix it. I thought it was a NAT problem, but now without NAT the problem<br>
still remains.<br>
<br>
The error is like this, when I call from pstn, the call goes trough<br>
Cisco AS5300, then goes to FS, then to it's final destination - Ip Phone.<br>
<br>
Now you can answer the phone, but you can't hear anything on any side.<br>
And FS returns lots of SIP 415 (unsupported media type) to Cisco AS5300.<br>
<br>
When you call from Voip phone to the same pstn number it all works well,<br>
so I'm starting to be confused more and more. (and in this case there is<br>
no 415 messages).<br>
<br>
I believe cisco is sending something that FS can't understand, in the<br>
INVITE's but that's just a wild guess cause I ain't sure what can FS<br>
exactly understand very well.<br>
<br>
Whoever want's I can send him a tcpdump, it's about 7mb tarred, so I<br>
can't send it to the list.<br>
<br>
Thank you all,<br>
<br>
Josip<br>
