Well, there's execute_on_preanswer<http://wiki.freeswitch.org/wiki/Channel_Variables#execute_on_preanswer> Can you get the it as a channel variable then? I presume hangup codes don't get set until the end. But if it's there you can act upton it. -Avi On Fri, Jul 5, 2013 at 9:33 AM, jay binks <jaybinks@gmail.com> wrote:
Hey all... I need to tap the collective knowledge of all.
In the scenario where I can get a Reason header in a Progress response ( 180 / 183 ) how can I control how Freeswitch will respond.
I can see 3 possible scenarios here, but it would be great to control which scenario was used.
1) Freeswitch just passes through the 180/183 with reason header... without doing anything with it.
2) Freeswitch can remove the reason header from the 180/183 and just play back the media stream that is accompanied.
3) Freeswitch can act upon the reason, and hangup the call .. ( if its a Q850 Cause code 1 for example )
now... where is this useful. well, what if I had a carrier that gave Q850 cause codes in ISDN progress messages ( number unallocated ) but then they played an RVA saying "number dialed is not connected".
They have done it this way to allow customer to choose how to handle the RVA ( do you want the RVA or not ) but does FS give me the ability to truly control this ?
( without needing to go as far as complex ESL applications )
