CUCM H225 stack process error similar to CSCtc48579

[UC Support]

Hi Community Members,

We're facing an issue with incoming ISDN PRI calls from the PSTN. It only happens when calling from specific numbers.

isdn switch-type primary-dms100

In the CUCM trace I see the following error:

17:33:51.114 |ProcessH225Message::decodeUuie ** ERROR  rc=4

D0081S: End of input reached before message was fully decoded; check PDU #5 'H323-UserInformation'.

This looks like CSCtc48579, but this is the platform:

c2900-universalk9-mz.SPA.151-4.M2

Active Master Version: 8.6.1.20000-1

Already tested with the command "signaling forward unconditional" but no luck. Attached the complete UUIE error.

Thanks in advance.

Hi

I just opened a TAC case for this.

By the way, the problem was in the Voice GW I was using H.323 SS, changed back to FS (default) and that fixed the issue.
