ATA 186 Reproducing DTMF tones from RFC2833 events

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?

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.
