[cisco-voip] 7937 Can't call out

[Wes Sisk]

"Cause i = 0x80AC - Requested circuit/channel not available"

CM can set this cause code but does not seem likely in this case. 

I believe there is a hint here:
May 27 15:15:47.325 UTC: ISDN Se0/2/1:23 Q931: RX <- CALL_PROC pd = 8  
callref = 0xB987
        Channel ID i = 0xA98397
                Exclusive, Channel 23
May 27 15:15:52.101 UTC: ISDN Se0/2/1:23 Q931: RX <- PROGRESS pd = 8  
callref = 0xB987
        Progress Ind i = 0x8288 - In-band info or appropriate now available
May 27 15:15:52.125 UTC: ISDN Se0/2/1:23 Q931: TX -> DISCONNECT pd = 8  
callref = 0x3987
        Cause i = 0x80AC - Requested circuit/channel not available

peer switch says to use channel 23 and everything progresses fine.
peer switch says to cut through audio and immediately the call is 
disconnected.

Just a guess - the DSP for channel23 either does not exist or is 
terminally ill.  Do you have enough DSPs for the total number of DS0's?  
Are you using Flex DSP allocation or static DSP allocation?
