SendDTMF
The SendDTMF command is used to send a DTMF message to a participant of the conversation. The target can be the caller, the callee or all participants. This can be useful in case of IVR systems.

How to use it?
Step 1: Make a call between two extensions. Use ListActiveCalls command to find the call ID of the call you want to send a DTMF message to. You can find the CallId in the response, between one of the <CallId></CallId> nodes.
Step 2: Send a DTMF message using a HTTP request as seen in the picture above. Paste the call ID you found in Step 1 in the CallId parameter of the request.
