Help with DTMF problem

Hello Group,

I have a CUCM cluster with 1 Pub & 1 Sub. This cluster sends calls to 8 PRI's connected into 2 6513 switches CMM module (4 going into each). Occasionally some users complain when they make calls that requires them to enter digits (phone trees) the entered digits are not recognized. My cluster controls 23 remote sites that either have bundled T1's or single T1's to me. Some even have 10GB fiber connections to me. All the T1 locations go into a DS3 I have in one of the 6513 switches. I am marking my signaling as CS 3 and AF31 and giving it 5% on the links coming to the central site where the clusters are. And yes I have bdtmf-relay h245-alphanumericb configured under my VOIP dial-peer on the Gateways pointing to each other.

This is not notorious (I mean it happens very randomly). But you know it doesn't work when the user(s) needs it, to them it doesn't work at all.

Does anyone have any idea(s) for me.

Thank you.
