Hi, Started to get this issue this morning with one of our MGCP gateways. Incoming calls are working correctly on an ISDN30, but outgoing calls are being denied, and re-routed via a backup route. Outgoing calls are hitting the gateway, but is getting a 'Requested circuit/channel not available' See trace below.
I've tried to change the channel selection order, but still the same. 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. Thanks, Hefin 2014-04-01 22:07:55 local3/7 Apr 1 21:07:54.602: ISDN Se0/0/0:15 Q931: TX -> SETUP pd = 8 callref = 0x0004 2014-04-01 22:07:55 local3/7 Sending Complete 2014-04-01 22:07:55 local3/7 Bearer Capability i = 0x8090A3 2014-04-01 22:07:55 local3/7 Standard = CCITT 2014-04-01 22:07:55 local3/7 Transfer Capability = Speech 2014-04-01 22:07:55 local3/7 Transfer Mode = Circuit 2014-04-01 22:07:55 local3/7 Transfer Rate = 64 kbit/s 2014-04-01 22:07:55 local3/7 Channel ID i = 0xA9839F 2014-04-01 22:07:55 local3/7 Exclusive, Channel 31 2014-04-01 22:07:55 local3/7 Calling Party Number i = 0x0081, '2456' 2014-04-01 22:07:55 local3/7 Plan:Unknown, Type:Unknown 2014-04-01 22:07:55 local3/7 Called Party Number i = 0x80, '622456' 2014-04-01 22:07:55 local3/7 Plan:Unknown, Type:Unknown 2014-04-01 22:07:55 local3/7 Apr 1 21:07:54.682: ISDN Se0/0/0:15 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x8004 2014-04-01 22:07:55 local3/7 Cause i = 0x82AC - Requested circuit/channel not available
