[Freeswitch-users] Question about using switch_caller_extension_add_application

[Woody Dickson]

Hi,

The problem is that I need freeswitch to continue executing the code after
switch_status_t channel_receive_message even when it gets error SIP code
from the destination.  Is that possible?

I know if I set up another action after my module in the dialplan.xml, I can
catch that.

But I would like the code to execute within the route that I have.  Is that
doable?

Woody
