<DIV><FONT face=Arial size=2>I'm running a TDM-400P with 2 x FXS and 2 x
FXO. I'm finding that there seems to be an odd relationship to
sound quality on the card to my local when connecting via a SIP
client.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When I'm on my local network, if I connect to
Asterisk via a SIP client (such as x-pro), and dial an outside line through the
card, sound quality seems quite good.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>However, when I'm at a remote location and connect
via the same SIP client and dial an outside line, the audio quality is fuzzy,
sometimes quiet, and generally more difficult to understand.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I spent a bunch of time troubleshooting the SIP end
of things, thinking that's where the problem was, until I realized that every
other SIP connection I make (from remote) yields a high quality call.
ie. I can dial another SIP client and maintain high quality audio.
Additionally, I can dial an extension that not only SIP connects to my server,
but from there goes out an IAX2 connection to another remote Asterisk server,
from there to another SIP client, and the audio quality is
excellent.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Therefore, I don't think the audio issue I'm
experiencing is on the SIP end.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Are there some wierd SIP -> ZAP timing /
conversion / other issues that could be causing this?</FONT></DIV>
