DTMF key pressed was "A", where is the DTMF A key?

DTMF key pressed was "A", where is the DTMF A key?

(OP)
This problem is in voicemail but sounds like a phone problem. The person says when they are leaving messages sometimes the call drops before they are done. Operational history viewer in MM says the A button was pressed. I guess that is the flash overrride from the old DMTF definition but I dont know what to tell the user they are doing to cause the problem. Where is the DMTF A button on a 4621?



RE: DTMF key pressed was "A", where is the DTMF A key?

More information needed. What release of Modular Messaging is being used and the storage server (Avaya MSS, Exchange or Domino) and the integration that is being used. Is the design on a system platform or classic design?

RE: DTMF key pressed was "A", where is the DTMF A key?

The DTMF A,B,C,D are military tones. By design if Modular Messaging (MM) receives one of these tones it will disconnect the call.

It’s essentially a toll fraud mechanism.

Section G of https://downloads.avaya.com/css/P8/documents/100041412 may help explain the functionality.

If an Audiocodes gateway is involved PSN003016r2 may also be worth looking into.

A good reference is http://en.wikipedia.org/wiki/Dual-tone_multi-frequ....

I would look for the source of military tone, but MM is working as we would expect it to. Good luck!

it may just be the users voice. Is it a female ? i have seen in the past a few times where the female voice can cause talk off and the system thinks it is an autovon tone.
