We currently have our inbound calls ringing 3 extentions, however I would like the following to happen.
When an inbound call comes in it rings the 3 extentions, first to answer takes the call. If no answer then it goes to voicemail. So far that's no problem. However, if the 3 extentions are busy I would like the caller to hear a message saying all operators are busy and to hold or if they prefer to press 1 to go to voicemail. If the caller chooses to hold I would like a message (like a commercial) to be played (only once) and then play the on hold music. This should repeat every 60 secs.
Is this possible?
Is there any documentation for PBXes, apart from the balloons that open when hovering over certain fields?
