<p class=MsoNormal><font size=2 face="Trebuchet MS"><span lang=EN-US
style='font-size:11.0pt;font-family:"Trebuchet MS"'>Hi all, I have a TDM2400P
w/ echo cancellation, 8 FXSs and 8 FXOs. They are installed respectively on
banks 1,2,5 and 6. The problem I am having is that when I make a call using the
ZAP channel, I can hear perfectly but the person on the other end is hearing my
voice with lots of ticks. It would seem I am making this call over a very bad
bandwidth which is not the case since this is the PSTN. My configuration files
are below, I have the latest versions of Zaptel, Libpri and Asterisk. I am
using Polycom’s IP301 and IP430 Phones. I would appreciate help since I
have to put this in production on Saturday. <o:p></o:p></span></font></p>
