[Freeswitch-users] shared line or other suggestion

I am currently trying to have the ability to place a call on hold and be able to pick the call up from a displayed list on a group of Polycom phones. I am currently using shared line but when the main phone places a call on hold the shared lines to not show the held call with the remote user CID but the primary phonesCID information. Does anyone have a recommendation that'll work better. I want to be able to see the remote CID of the caller who is on hold.
