[Freeswitch-users] Multiple attended transfer of an inbound call

Wed Nov 20 04:12:29 MSK 2013

Hi team,

I have Freeswitch setup so when an incoming call is answered, it can be
transferred to another extension or into a valet parking lot. That`s fairly
simple using the transfer key of the phones.

What I am having issue with is if the extension that answered the
transferred call (or picked up the parked call) wants to transfer it
somewhere else or park it again, things will work until that extension hangs
up; meaning I hit the transfer key and make the other extension to ring, it
answers but once I hang up, everything hang up so the original incoming call
is not connected.

I get this in the log:

-- The call is coming in
