[Freeswitch-users] Transferring calls - can Freeswitch instruct the up-stream provider to do the transfer?

[Brian West]

yes, see deflect vs redirect on the wiki, deflect sends a refer and the redirect sends a 302, I don’t know of any provider up stream that will take a refer and act on it.

However in this case, Freeswitch is really only the end point and is not the client's PBX system. The client would like an option that will cause the incoming call to be transferred to a specified destination. The destination is an outside number and not a Freeswitch extension.

But even if that works, it would mean the incoming call is still being routed right through Freeswitch and out again to the destination.
