<DIV><SPAN class=635520421-22032005><FONT face=Arial size=2>I am using a SIP
softphone (X-lite, SIPPS or Firefly) connected to an Asterisk v 1.0.3 PBX.
The PBX is also connected via a ISDN-PRI crossover cable to a Avaya Definity
Generic 3 PBX via a TE405P card. All outside of the office calls go
through the Definity. Here's the issue:</FONT></SPAN></DIV>

<DIV><SPAN class=635520421-22032005><FONT face=Arial size=2>Calls to internal
SIP extensions, Definity extensions, other offices within our private
network (through the Definity), and cell phones are great. When I
call outside of the office to POTS lines (like my home), there is a most
noticeable echo of my voice. The party on the line hears no echo.
Any efforts on the configuring the SIP softphones, and within zapata.conf, have
been for naught.</FONT></SPAN></DIV>

<DIV><SPAN class=635520421-22032005><FONT face=Arial size=2>Is this problem
common for ISDN-PRI connections?</FONT></SPAN></DIV><div><p><font size="2"><FONT face=Arial color=#0000ff size=2><BR><BR>
