I have a wierd issue, where only Vonage calls are having issue
When someone call from Vonage, it goes to auto attendant, but it doesnt recognize the input. I tried more than 10 times and all call failed giving input.
I am sure this is a dtmf issue, but want to make sure with the configuration
Here is the dial-peer for incoming call
dial-peer voice 2001 voip
description ** cue auto attendant number **
translation-profile outgoing PSTN_CallForwarding
session protocol sipv2
session target ipv4:10.1.10.1
voice-class sip outbound-proxy ipv4:10.1.10.1
dtmf-relay sip-notify rtp-nte
Please let me know if you need more information.
Thanks in advance
Please check the running config of the CUE.
what is the dtmf-relay method and chenge it accordingly so on both side it should be rtp-nte. So if it is rtp-nte only under the dial-peer is should be the same under "ccn subsystem sip" in the CUE:
ccn subsystem sip
gateway address "10.1.10.2"
Please make this and test again.

I made these changes and tested again.
Now I can give input from any phone but not from Vonage phone
I tried different Vonage phones.. Same issue
From my past experiences, it was always a Vonage issue and not the the phone system issue. Vonage has had a history of DTMF issues in the past. Call Vonage first or use the Vonage phone to call something else that requires DTMF codes and see if they go through.
Thanks for the information Thomas.
But when I try Bank of america or any number, calls are successfull. Issue is only when I call my UC540
Here is the call flow
1. Call coming to UC540
2. Gives a welcome greeting with options
3. User tries to give input , but UC540 doesnt accept the input
This is happening only with Vonage calls
Now I have another issue(with all calls)
Some times when customer gives the input, it accept it and immediately hungs up.
Any idea why it is happening like this?
Make so a call from Vonage customer can be answered on a Cisco phone.
Have caller press few keys. If no tone is heard, then it is Vonage fault, as suggested above.
Regarding the second problem, update to latest SW 8.6.0, and check again.
