[Freeswitch-users] Unbridge Call

[Ian McMaster]

Hi Luiz,

Try the following to control the a-leg and b-leg after a successful bridge,
using ESL.

1.  Create an extension in your dialplan for the b-leg; this may simply
hangup, or play a message then hangup

If you use:
sendmsg
call-command: hangup
hangup-cause: CHANNEL_UNACCEPTABLE\n\n

then both sides will drop.  Try sending this on the socket instead (you
will need the uuid from the CHANNEL_DATA event for this one):

api uuid_transfer <uuid> -bleg <B_LEG_EXT> xml default
(this should get rid of bleg and keep a-leg.for further processing)

Hope this helps,
Ian.
