<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Just for clarification, this defect is unrelated to the issue that was described below. The defect you’re referring to is related to RouteListCdrc detecting
the destination gateway/trunk as down when in actuality it is up and available. Hefin swapped the patch cables between two T1s and the problem followed the swap. If this defect was encountered, I would suspect the problem would stay on the endpoint since swapping
cables are transparent to RouteListControl and RouteListCdrc.<o:p></o:p></span></p>

Whats "sh isdn q931 status" showing?.<br>
<br>
Do a "show isdn status" this will show which channels are open and which ones are out of service. If you have some channels up and its mission critical you can always busy out the "bad" channels effectivily making a customized fractional pri<br>
<br>
And yes do engage the vendor at this point. A shut no shut on the isdn interface would not hurt at this point either.<br>

Subject: [cisco-voip] Requested circuit/channel not available<br>
<br>
<br>
Hi,<br>
<br>
Started to get this issue this morning with one of our MGCP gateways.<br>
Incoming calls are working correctly on an ISDN30, but outgoing calls are being denied, and re-routed via a backup route.<br>
Outgoing calls are hitting the gateway, but is getting a ?Requested circuit/channel not available? See trace below.<br>
<br>
I?ve tried to change the channel selection order, but still the same.<br>
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.<br>
<br>
Thanks,<br>
Hefin<br>

I've got 2 isdn cards in the gateway, and before things get busy this morning, I'm going to swap connections to see if the fault follows the connection, or stay with the PRI card.<br>

James,<br>
<br>
Whats "sh isdn q931 status" showing?.<br>
<br>
Do a "show isdn status" this will show which channels are open and which ones are out of service. If you have some channels up and its mission critical you can always busy out the "bad" channels effectivily making a customized fractional pri<br>
<br>
And yes do engage the vendor at this point. A shut no shut on the isdn interface would not hurt at this point either.<br>
<br>

Subject: [cisco-voip] Requested circuit/channel not available<br>
<br>
<br>
Hi,<br>
<br>
Started to get this issue this morning with one of our MGCP gateways.<br>
Incoming calls are working correctly on an ISDN30, but outgoing calls are being denied, and re-routed via a backup route.<br>
Outgoing calls are hitting the gateway, but is getting a ?Requested circuit/channel not available? See trace below.<br>
<br>
I?ve tried to change the channel selection order, but still the same.<br>
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.<br>
<br>
Thanks,<br>
Hefin<br>
