[Freeswitch-users] Dialplan Tools: bridge - pipe vs. :_:

[Avi Marcus]

See: http://wiki.freeswitch.org/wiki/Freeswitch_IVR_Originate

Enterprise originate

The so called 'enterprise originate' syntax is a way to simultaneously
originate multiple calls in several threads (regular simultaneous originate
is single threaded). To use it simply separate valid dial strings by :_: .
Each dial string can have its own {} and [] blocks and can themselves be
simultaneous or sequential (containing ',' or '|') as above. To add channel
variables to the entire enterprise originate use <> blocks:

originate <all_threads=true>{first_thread=true}sofia/gw/foo/bar:_:{second_thread=true}sofia/gw/foo/baz

This can be helpful when dealing with call forwarding. Without it,
FreeSWITCH™ would drop the simultaneous dial and transfer to the forwarded
extension.

For example, I'm bridging to two SIP phones, 101 and 102, with "," between
them. 101 redirects to some other URL. 102 will now stop ringing. With :_:
it wouldn't.

By default each new thread is it's own A-leg in the CDRs. You can access
the variable ent_originate_aleg_uuid to put the call back together.
