Mute & Unmute with DMCC?
Hello everyone,
I would like to know how we can mute and unmute using the DMCC.
Is this possible?

The simple answer is no. Mute is purely a function local to the handset. -
As flynn1 indicated typically mute is a local function at the phone. CM has no control over the feature.
There is a very expensive way to implement something similar but it has some things to look out for.
1) it requires an Advanced TSAPI License - which is a site license on AES for a specific Communication Manager. This license is relatively expensive for the functionality it provides in this context.
2) the feature/API to use is 'SelectiveListenHold" This prevents a specified party from hearing another specific party (it is kind of an inverse mute, but you can make it function like mute if you stop all other parties in the call from hearing the 'muted' party.
3) The SelectiveListenHold feature is available through TSAP, JTAPI, and DMCC APIs.
4) Since a specific message must be sent for each other party in the call, in conference situations it doesn't take effect all in the same millisecond as it would if a true mute was used.
5) Since it is an action CM is taking (not the phone device itself), to unmute you must use the SelectiveListenUnHold API.
6) If the call is conferenced or transfered subsequently, additional SelectiveListenHolds would be necessary for the new parties in the call.
It is pretty messy way to implement a mute but a few applications have had requirements such that they utilized it.
