[cisco-voip] CUCM 2851 MGCP VGW to InTouch VRU Digit issues

[Nick Griffin]

Customer has a VRU connected to a CUCM system, analog on a 2851 running
12.4(9)T7, integration is via MGCP controlled FXS/FXO ports to VRU system,
published numbers for the VRU ride FXO ports on the same Voice Gateway. FXS
ports are configured in a hunt group in CUCM. System has worked fine for
nearly a year, recently we upgraded CUCM from 5.1.3.1105-2 to 5.1.3.4000-4
and customer is saying approximately since this upgrade users have had
issues with the system recoginizing account numbers and pin numbers. Could
this be an issue with MGCP since the upgrade? I've tried adjusting output
attenuation on the voice ports, etc, but the issue still occurs. Has anyone
ran into this in the past? Thoughts appreciated.

Active Version: 5.1.3.4000-4
Inactive Version: 5.1.3.1105-2

Thanks in advance,

Nick Griffin
