How to send DTMF signal on MCU to MCU??

Hi Experts

Our setup is we have VCSc&e,TMS,Conductor and two 7010 TIP servers. TIP server managed by conductor

We trying to join our client MCU bridge from our MCU the problem is we are not able to send DTMF signal.

In brief

Our client MCU is in Public IP and  we dial the client MCU from our MCU, calls are connected after that client MCU ask for Meeting ID and Password. Plese let us know how to send the DTMF signal from MCU (we have 7010 TIP server and TIP server managed by conductor and client MCU is Cisco 5300 series)




Re: How to send DTMF signal on MCU to MCU??

Which versions do you run?

I think conductor should have a capability to do so, there might be something on the website as it is on

the MCUs, but at least you should be able to do it via the API:


Status: active
Sends a DTMF string to some or all participants in the specified conference. You must specify the

conference and the DTMF string (up to 50 characters).

If you don't specify a participant, the string goes to all participants; otherwise, you may specify either a participant who will receive the string or one who will not receive the string.

To identify the conference, use conferenceGUID instead of conferenceID, not both. conferenceGUID

Type: string

Globally unique identifier of the conference.


Type: integer

Deprecated. Use conferenceGUID instead.

Unique conference identifier.

The other thing I would try is to simply dial DTMF from an other endpoint in the conference.

At least on the MCU you had an option to either mute or pass through DTMF, not sure how the TPS behaves.

If all things do not work out and no one else has a working suggestion you can always file a feature request.

Or tell them they shall call you ;-)
