[Freeswitch-users] Originate between two registered endpoints

[Jonas Gauffin]

Hello

I'm originating a call from one phone (caller) to another
(destination). Both are registered in FreeSwitch.

Why do the destination phone get a channel_state HOLD event just after
channel_state RING?
Isn't hold only supposed to be sent when the user actually put's
someone on hold?

I'm wondering since I'm handling all channel events in a switch
monitoring program, and I should show "offering" (a call is being
offered to the phone) and not "onhold" in this case.

I'm not posting this as a bug since it might just be me who doesnt
understand the event flow (in that case, please explain why the HOLD
state is there and how I can see when the call is actually being put
on hold).

The log (just those two events, tell me if you need the whole log):
