ATA 186 Reproducing DTMF tones from RFC2833 events

Question

I am trying to get my ATA 186 (running version SCCP 3.x under CCM 5.04a) to reproduce received rtp-events. This is supporting a third-party IVR system that is connected via analog ports.
The IOS gateway that is sending the events is configured for dtmf-relay rtp-nte, and I can see the RTP events being received at the ATA. However, all I hear at the ATA is nothing or clicks.
I have the audiomode setting on the ATA set to 0x00150015 as is recommended in the ATA administrators guide.
Does anyone have DTMF working through the ATA?

Answer 1

Hi Kevin,
have you debugged the ATA with prserv.exe?
I had some issues in the past with a PESQ tester, and setting the audiomode to 0x00120012 helped for me.
