[Freeswitch-users] Call back through SIP trunk

[Michael Collins]

Hi Sina,

Were you able to figure this one out? Also, I didn't see anywhere in this
thread what the outbound leg would be connected to. For example, when you
call out to the caller ID number received on the initial call, what will
the other leg be connected to? Do you have a user or an IVR or what? Just
curious. You can't make an outbound call without connecting that leg to
something.
