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. You can see how to use this command in
a HTTP request and what HTTP response you will get from the phone system (Figure 1).

The call ID of the call you want to run the SendDTMF method on.
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.
