Hi,
I have a requirement to connect our CISCO IVR with and external IVR and send the data in the form of DTMF tone.
Any suggestions how to achieve this option? I found the sample application to make an outbound call from IVR but how do i pass the data as dtmf tone?
Please advice
Thanks & Regards,
Moiz

Is the DTMF tone your sending unique to each call, or is it a static value to enter an access code?

Moiz,I haven't tried this on Cisco, but on other IVRs we had all the DTMF tones pre-recorded in files named DTMF1.wav, DTMF2.wav etc. And to play out DTMF tones, we would just speak the audio files in the appropriate order. You could use the ICM microapp PlayMedia (PM) and play the tones you need to send.

You can use the wav files meant for the voice gateway. These should read en_0.wav, en_1.wav etc. They are DTMF equivalents of the numbers.
You can also use the 'HF' prefix if you are sending these numbers using a transfer node. A destination like 'HF123456789' will do a hook flash following by the 9 digits in DTMF. Now if the called destinated is say, 123456, then the remaining 3 digits, 789, can be interpreted as caller entered digits at the destination.
I have also been able to use this approach as part of a 'Converse-on' operation with an Avaya PBX, where the PBX sends some digits into CVP and I can include some VDN information in the response back, using 'HF' nodes. Note: You will have to get the right inter-digit times when dealing with different PBX systems.

Exactly what I was getting at. I couldn't find DTMF tones prerecorded on our media server anywhere; however, you can use VOX Studio to generate the tones you need and wrap them into a .wav file with the appropriate conversion settings.
