We have Call Manager Express 4.1 running on a 2821 router using integrated Unity Express voicemail. We currently have 8 POTS lines total that are connected to FXO ports. The first 4 lines are in a carrier hunt group and configured to ring to the auto attendant. All this is fine. We have another another 4 lines used for a helpdesk connected to another 4 FXO ports and these lines are in a seperate carrier huntgroup. I would like to have these lines ring directly through to user phones that have helpdesk extensions assigned. I currently use 7961 phones and have unique extensions for each helpdesk line that is represented as a line on each of the users phones. In this config I like the fact that one user can put a call on hold and another helpdesk person can see the call and pick it up if this is on hold. I am wondering if there is a better or easier way to do this. My concern is if we want a 5th and 6th helpdesk line. In this current scenario we would be out of phone buttons. Any recommendations or help appreciated.
