Duplicate DTMF for Video calls only in UCCE 7.5

Dear All,

We have Cisco 3G router Cisco AS5400XM (BCM)  with one E1 PSTN line over it. We are facing duplicate DTMF issue for video calls only. (Audio calls works perfectly ).

Calls flow is comprehensive call flow

3g mobile - PSTN E1 -> 3G router -> CVP -> ICM -> CVP -> Call Manager

When ever user makes Video call to Contact Center via 3G mobile, call get connected and ask the user to enter user id. 

When user enter DTMF as 20126, CVP is getting as 2200112266.

This happen only while enter the user id and 3G video calls.

Please help us.

Thanks in advance.
