[cisco-voip] q931 cause codes

[Wellnitz, Erick A.]

CAR shows the same as the sdi trace.

102

Call terminated when timer expired; a recovery routine executed to recover from the error.


Is there any way to determine which timer expired?

Oh, and CUCM internal codes are documented in the CAR guide:

Externally (communicated to to h.323 gateway or MGCP gateway) the cause codes do have to be in the subset of q.931 defined codes.

Internally (for call legs inside CUCM) there can be more cause codes. SDI logs contain both internal and external codes so you could see either there.  What is the complete trace line where you see that cause code?


I *think* in 0x0810E6 you're going to focus on 0x10 = 16(decimal) = normal call clearing.  It would be good to see the original SDI or SDL trace line to confirm.

Okay...are the q931 disconnect messages not consistent between debug isdn q931 and the sdi logs?

SDI log (via VLT) shows cause code of 0x0810E6 but this doesn't coincide with the Cisco documentation re: q931 cause codes.
