Cisco Unified Border Element (SP Edition) supports two out-of-band procedures for DTMF relay. However, you can configure DTMF relay to use SIP NOTIFY messages for transmitting DTMF tone information.

I figured it is out of band for the DSP to pick up and the, somehow open and hold the channel long enough to make the tone.Īnyfixs for this? Ideas help free beer? LOL peace out. If no DTMF relay method is configured, the tones are sent in-band. We call in sip currently but the conference calls are in iax/voip.įirst wack at a change I did to get it to work with out the, on the outside of the pound sign is:ĭtmfmode=rfc2833 in the agent setup for each agent iax.confĭtmfmode=inband added to the truck for sip However, if you add ,#, to the DTMF field, then the tone is sent but with a delay of about 2 seconds. The current DTMF postings for Vicidialnow (latestest and greatest) does not send a DTMF tone long enough to be picked up from the third party group. However, we have to do 3rd party verification.
