Trying to come up with a solution to replacing the M2250 console with an M3904 phone. I know that I can build an ACD que with 0 as the number but here the deal. They want to be able to put a call on hold while they answer another call. Pretty sure ACD won't allow that. So basically want several appearances of a number. Anyone seen or done something like this. They also want unanswered calls to go to a RAN if no answer with a couple of rings and then present the call to the new phone. Thanks for any help on this.
