[Freeswitch-users] ORIGINATE_DISPOSITION

Tue Aug 16 21:54:47 MSD 2011

The originate disposition of A leg will always have the last known status from B

originate, by default, returns when:

1) media is established on a specific outgoing leg, answered or not
2) all outgoing legs are terminated.

if you call somewhere that uses early media, the originate will end
setting originate_disposition to SUCCESS meaning that a live channel
was produced.  Now the bridge will begin between the A and B leg.

When the bridge ends if the B leg is hungup, its cause will be stored
in "bridge_hangup_cause"

if you want to keep the originate from ending when early media is
established you can add {ignore_early_media=true} or
{bridge_early_media=true} prepended to your dial string and the
originate will never return untill all outbound legs are either hungup
or one is answered.

You should take some time to expand your mind to the different
paradigm in FreeSWITCH where you may have as many as 10 outbound legs
at once in a forked-dial situation and some of what you think is
simple and obvious will quickly dissolve.

Another thing you can do is set the variable "failed_xml_cdr_prefix"
on the A leg.
This prefix will be mixed with an incrementing variable for each
outbound call leg and in the case of a failure the entire XML cdr will
be set into a var on A leg.

for instance if you set failed_xml_cdr_prefix=foo you would get foo_1
foo_2 etc depending on the number of outbound call legs.

Additionally you can set copy_xml_cdr on the A leg and when the bridge
ends you will get a complete CDR for B in the "b_leg_cdr" variable on
A

Finally you should really go with the flow of how FreeSWITCH is
engineered and try to keep your accounting logic in a separate place
and monitor the XML-CDR, CDR-CSV or event_socket +
CHANNEL_HANGUP_COMPLETE events to process this information.  There is
much more to a call and what happens when it's transferred etc than
what you can get in a single monolithic perspective of inside the
channel.  Plus it's conter intuitive to put routing, application and
accounting logic in the same place.
