<DIV><FONT face=Arial size=2>TDM400 port <=> * <=> sip
phone</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When I make a connection between these phones the
TDM400 can hear the SIP phone just fine and the SIP can hear the TDM400 port
just fine most of the time. But sporadically you can not hear the TDM400
on the SIP phone it sounds like the microphone on the TDM400 port goes
hypersensitive and it is like you are overdriving the microphone on the TDM400
and it has a lot of distortion. You can hear it on both sides. The
SIP conversation is still good on the TDM400 but the TDM400 conversation on the
sip phone is distorted and unusable.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Tried several different ports on the TDM400, tried
different codecs. All the same story.</FONT></DIV>
