<p class="MsoNormal">I’m making use of local route groups. I have 4 PRI’s with MGCP configuration to the PSTN. We also have a LCR via a SIP trunk to the CUCM. As I’m using local route groups, My route group contain Tom down the Sip trunk and then the 4 PRI’s.
 When the Sip trunk fails, I get a <span class="st1"><span style="color:black">SIP</span><span style="color:#222222"> response
