Bill H Posted May 12, 2008 Report Share Posted May 12, 2008 When a call is transfered from PBXNSIP to a cell phone how can I (if at all) transfer that call back from the cell phone? I tried *77 which is the Transfer Feature Code and that did not work. Is it at all possible? Bill H Quote Link to comment Share on other sites More sharing options...

Bill H Posted May 13, 2008 Author Report Share Posted May 13, 2008 Nope, that is not possible... The call is on a trunk. Yes I do realize that it is on a trunk, but the same trunk is also connected to the pbx at the same time. I thought that the Inband DTMF detection: On/Off setting had something to do with this feature. I mean that the PBXNSIP would monitor the call/trunk/extension looking for *77 to initiate a transfer. Since this isn't the case, what then does the Inband DTMF detection: On/Off actually do? Bill H Quote Link to comment Share on other sites More sharing options...

This is because otherwise it would be a huge security hole (transfer the call to somewhere in Cuba). We could make an exception because the PBX knows that the call is to a known cell phone (and it also knows what user to charge). It is just that it is not in there. And also, currently the cell phone would have to put the call on hold first - that is practically not possible with today's cell phone providers. That would have to be changed as well.
