<p style="margin:0in;font-family:Calibri;font-size:11pt">We are currently
having issues with out MGCP gateway with the E1 channels going out of service
once in few weeks time. We have the configs checked by Cisco and the whole
hardware replaced including the LCN coming in from PSTN. Cisco guys initially
proposed to change the echo cancellor from 64 to 128 on the gateways. Which we
followed. </p>

<p style="margin:0in;font-family:Calibri;font-size:11pt">A single channel
going out in the middle of the day which we have to reboot the whole controller
and lose all the active calls is causing a nuisance. </p>

<p style="margin:0in;font-family:Calibri;font-size:11pt">Not sure what is the
cause for it.<span style=""> </span>We have been going through
the logs and not sure what exactly should we check the logs for!!! i.e.<span style=""> </span>Will it be the CUCM throwing the channel out
of service or the gateways itself.</p>
