[Freeswitch-users] Attended transfer to a conference room

Fri Sep 7 02:39:53 MSD 2012

Thanks Stanislav, your idea is good, but works only for incoming calls. I know we could trick the idea around to have it work for outbound calls as well, but it sounds to me as being too much of a workaround for something so trivial.

I'll play around some more and loop back my calls if I have to.

Thanks for this and have a good night,
Emrah
