Kishorepv,
How do you know its DTMF related? I dont see how any one can understand 3 lines of log without really knowing what the problem is.
What issues are you having? When does it happen? What is your call setup?

Hi Aokanlawon,
DTMF is working for 20 - 30 mins * 6 is for mute and Un Mute,* 0 Is for Operator,After some time If we press the * 6 it is not saying anything & * 0 is also no action.What could be the problem ?
It happening for every call in the Audio bridge.

What IOS are you running? You may want to upgrade your IOS.

Hi Aokanlawon,
IOS Version - " c3845-adventerprisek9-mz.124-20.T3.bin"

I have looked at that IOS and looks like you are hitting this bug:
CSCsc49582 - Problem sending asterix * in DTMF via PRI gateways
Description
Symptom:
Customer found problems with behaviour where DTMF digits sent between IOS versions via PRI voice
gateways.
Conditions:
Cisco CallManager 4.1(3)sr1
Cisco 3725 IOS MGCP voice gateway with NM-HDV, VWIC-2MFT-E1
Problem happens with 12.3(14)T4, 12.4(2)T1
Customer uses IP Phone and calls PSTN to the alarm system;
alarm system answers and plays DTMF to ip phone user;
ip phone user sends DTMF via keypad, eg: 011204, and receives another DTMF sequence from alarm system;
ip phone user keys '*4' to disconnect the call
Normal conditions the call would be disconnected.
Workaround:
Customer has used 12.3(11)T7 successfully.
Further Problem Description:
When fault occurs call idles out for approx. 30sec before disconnect
So I suggest you upgrade your IOS to a much later version.

Hi Aokanlawon,
CUCM Version is 7.1.5 Please provide me the excat IOS version.so that i can try.

I understand its cucm 7.1.5. But the symptoms look very similar..So If you want to resolve the issue I suggest you upgrade your ios. There is no other way to explain the problem you are facing. Its intermittent. So its not configuration related. Unless you have some hardware related problems, which I dont know how it will affect dtmf issue, because dtmf is essentially software related (done in IOS).
Recently I had to upgrade my IOS because I had issues with supplementary services working intermittently on calls. Sometimes it works other times it doesnt. Things like this are usually bug related...
It might just be worth you trying to do an upgrade and see if it resolves it..and if it does not then you look further..
