I want to do this, but I cannot find the correct answer.
A call (external) enters the system, but the secretary is not in his/her place (A) at the moment. Customer prefer to configure a Pickup group (A+B+C), because they work in a close environment, and don't want a hunt/blast group so all phones ring or call waits for too long. Until someone pick up the call (B or C), intended secretary phone (A) should still ring, until someone pick it up or Unity takes over... so far so good.
Another person (B or C) picks up the call, but it was not intended for him/her, so he knows the extension for whom the calls is intended (in another floor/room, say Z), outside the huntgroup and tries to transfer it. The problem here is that no matter what I try, the transfered is a _consulted_ one, so the call doesn't return to this person, say B or C, after a while, => call is lost. It behaves like a blind transfer, but originator hear the MoH. If call is rejected verbally B or C cannot re-capture the call. Originator is hung up.
The weird thing is that, when calls enters the system, A is absent (the secretary), B picks up, then B transfer to A because he think the secretary is back, but if he/she is not, then AFTER a while, calls return to B !!! which works perfectly as intended, only with A and B, or A and C.
Now, to some info, because this scenary is for real: B and C are 7911 configured as dual-line.
System is CU520 and A is a 7960 [this has to be the key]. Z (the phone in another room) is 7911 too dual-line
What I have tried:
transfer-system ANY-CONFIG-HERE (<--- this doesn't work for the aforemention scenario)
transfer-system full-consult dss (<-- without it, transfered calls from A to any becomes full blind!?!?!)
ephone-dn 99 dual-line (<---B)
transfer-mode consult (<---this doesn't work either)
This has to work for any call intended for the pickup group... or at least for B.
What do I need to search for, conference, hold, transfer, settings? I tried to resolve this temporally with a Park Slot, but that was not the intended behavior.
