DTMF Relay outbound calls

vectraeee
Level 1
Level 1

Hi,

i've a problem,

in my dial-peer XXX voip i've configured the DTMF-Relay, so the incoming digit will be relayed by the voice gateway, but on the outbound calls, there is no possibility to configure the dtmf-relay so when i call an ivr my digits are not relayed by the router....how can i configure this parameter for outbound calls?

P.S. I'm using MGCP between voice gateway and callmanager 4.1(3)

BR,

Claudio

How is the gateway connected to the IVR? Is it using FXS/FXO or T1 lines? If yes, then you don't need dtmf-relay for outbound calls as the dtmf-relay applies only to the VoIP side of the call.

Also since you are using MGCP, you need to use the following command for DTMF relay on the VoIP side

mgcp dtmf-relay voip codec all mode cisco

Regards,

Anup

The IVR is an external systems, for example when i call the McAfee company there is an IVR the aswer the call.

My router is connected to Telecom with an ISDN Bri.

So i need the dtmf relay for the outbound calls.

I've configured this:

mgcp dtmf-relay voip codec all mode cisco

in my router, but it seems, it doesn't works.

This is my router configuration:
