We have CUCM 8.6 and a Valcom SIP page control. What we have been asked to do is give our receptionist the ability to play a prerecorded message over the page system by pressing a button on her phone. What I was thinking about doing is setting up a call handler in Unity in which she would record the message she wants to play as the primary greeting. Then, I am trying to find a way to set up a button on her phone to automatically establish a conference between the DN of that call handler and the DN of the page controller.
My thinking here is that as soon as the conference is initiated, the call handler will playback the greeting and since the page controller is also in the conference, that message will be played over the external speakers.
I would set the call handler to hang up after playing the message, so it's my understanding that as soon as she presses the button to initiate the conference, she could hang up and the conference would remain active until the call handler finishes playing the greeting and then hangs up, at which point the conference would terminate.
So the root question is how can I program a button to initiate a conference between two other DNs?
