Edit: It does look like this is idential to an IN PROGRESS idea thread:
https://www.3cx.com/community/threa...s-for-queue-and-ring-group-in-progress.43410/ Great! Hope it makes it into the next version!
I just tested this, and this works fine on our phones n V14. If a second call comes in from a ring group to an extension with "allow multiple calls" checked, it can be picked up by pressing "answer", and it automatically puts the other call on hold. If a third call comes in, it can be picked up by pressing "answer", and the 2nd call is automatically put on hold. We've been running with this feature enabled for a couple years without issue. I just tested, and I can un-hold each subsequent caller successfully, or transfer them somewhere else.
I'm very concerned this is not a supported configuration for 3CX.
Telling a client to hire extra staff to answer phones is not a solution.
Using Queues is not a fix to this issue, as Queues really don't work well for a normal office environment - you can't ring multiple extensions at once properly with a Queue. Either Queues needs to be expanded to be a fully-functioning replacement for a Ring Group, or Ring Groups need to be able to pick up multiple calls.
BLF is not a fix for this issue, as you'd need a BLF for every additional caller you want to put on hold.
Parking calls would work in this scenario, as long as *one* additional call can be answered when dialing a ring group, but it sounds like that's not the case currently.
So, does this mean this feature is *broken* in V15.5? Or does this only come into affect on SIP phones that don't have two line appearances (E.G. most phones list your extension on both lines, specifically so you can take multiple calls!). If so, that will mean we'll have to stop being a 3CX partner, as we can't have half of our clients requiring a different phone system. That's just silly.
