<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Started to get this issue this morning with one of our MGCP gateways.<o:p></o:p></p>
<p class="MsoNormal">Incoming calls are working correctly on an ISDN30, but outgoing calls are being denied, and re-routed via a backup route.<o:p></o:p></p>
<p class="MsoNormal">Outgoing calls are hitting the gateway, but is getting a ‘Requested circuit/channel not available’ See trace below.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve tried to change the channel selection order, but still the same.<o:p></o:p></p>
<p class="MsoNormal">I’ve checked everything that I can think of, and I’m beginning to think that this is a Telco issue, but thought that I’d ask the group to see if there is anything else to check before I take it up with BT.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
