Hi all, After configuring my HQ GW as MGCP, then configure my T1 to register with cucm , I was govern by the lack of the DSP resources, which force me to define only 16 channel out of the 23 on my pri-group under the T1 controller configuration !!
here is the config : controller T1 0/0/0 pri-group timeslots 1-16 service mgcp Then I faced a problem with my outgoing calls , the calls was dropping due to the cause "*Requested circuit/channel not available*" My Question here, as there is 16 channel in my Pri-group are already configured, why all calls get dropped with cause of non availability of the resources, Why not to use one of the available channels (1-16) Appreciate your help here is below the output of debug q931 for one of my outgoing calls: *SDN Se0/0/0:23 Q931: TX -> SETUP pd = 8 callref = 0x000F * * Bearer Capability i = 0x8090A2 * * Standard = CCITT * * Transfer Capability = Speech * * Transfer Mode = Circuit * * Transfer Rate = 64 kbit/s * * Channel ID i = 0xA98390 * * Exclusive, Channel 16 * * Display i = 'HQ PH1' * * Calling Party Number i = 0x2181, '7772022001' * * Plan:ISDN, Type:National * * Called Party Number i = 0x81, '911' * * Plan:ISDN, Type:Unknown* *ISDN Se0/0/0:23 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x800F * * Cause i = 0x82AC1810 - Requested circuit/channel not available*
