I am having a huge problem converting my branch users over to VOIP. They have been using key systems for 20-30 years and want the Line 1, Line 2, Line 3..functionality. There is actually a good reason for this, our locations (17 of them) all have a central sales counter where usually about 5 people stand each with their own phone. Calls come in and ring to all sets on counter. Person 1 answers and tells the caller to hold as another call is coming in. He needs the Person 3 to "pickup line 1". Instead of Person 3 just pressing the Line 1 button, the call must be transferred or parked. As more and more calls come in, they get confused easily. I have been trying to work this out with Switchvox (Digium) and their answer was a flat out NO. I should have researched more. I am looking a 3CX to replace this system I just installed. Even though I created BLF keys for 5 parking lot spots, apparently this is still an issue. Can 3CX do it any better? Is there a way to assign one trunk to one button on each phone since I am using POTS? My main reason for moving in the VOIP direction is transfer calls between locations and the software functionality. I know that Shoretel, Allworx, and AdTran have the key system emulation, but they are expensive options. Thanks for any help.
