Sending DTMF back to CLI when call answered

Sending DTMF back to CLI when call answered

Sending DTMF back to CLI when call answered

Hello fellow members,

A bit of explanation to what I'm trying to achieve - I have a safety/s.o.s device which can initiate a call to predefined number/s. The tricky bit is that the device requires the button on the keypad to be pressed by the person who answers the call, otherwise the device classifies the call as being answered by answering machine. I was wondering if utilising Avaya IP500 V2 in conjunction with VmPro (both on version 9.0.2) there is a possibility to send the DTMF code (predefined) back to the CLI when call is answered automatically by VmPro. Any other suggestions are welcome.

Thank you

RE: Sending DTMF back to CLI when call answered

Depends what trunks you're using, on analog or PRI/T1 you could just play the DTMF tone in a VMPro announcement, on SIP it depends if DMTF is sent inband or not.

If it's an safety/SOS device that requires that it works 100% of the time I would avoid this kind of solution.

Hi Janni78,

thank you for the info. I forgot to mention that we are on SIP. Unfortunately my knowledge about SIP and Avaya is quite limited - I can find my way around it however details like inband or whatever do not sound familiar to me.
In regards to the solution itself - I'm trying avoid relying on the person to press the button on the phone due to fact that these emergency calls are for one of many clients only (inbound call centre).
If you can point me in the right direction how at least I can set it up to perform some tests it would be great.

Thank you
