<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Ok so this issue has come up again. It now
appears, much to my dismay that it is not only with the Nortel integration. I
have had complaints on other calls including IP phone to IP phone. The IP
Phones are on the same network, same VLAN and even the same switch. It is a
4510 switch that is fully loaded. I only have about 100 IP phones it now the
rest are data connections. It almost seems like an IP routing issue
because the call only drops one way and it eventually comes back as long as no
one hangs up. <o:p></o:p></span></font></p>

font-family:Arial'>I have a 3845 configured as an h.323 gateway. I have four
PRI’s connected to this gateway from the PSTN. I also have a single PRI
connected to this same gateway used as a tie line to a Nortel system. I have had
no complaints on calls going or coming from the PSTN. I have had several
complaints on calls to and from the Nortel box. The call could be setup fine
and you are talking but the call basically goes silent for about 10 – 15
seconds. The call does not drop only silence. Also if you stay on the call the
audio starts up again. I don’t think it is an IP routing issue because
calls to the PSTN work correctly and calls do work to the Nortel it just will
stop for a few seconds. There are no slips and no errors on the line. </span></font><o:p></o:p></p>
