Jiri,
That would be great. When this is done, would you be able to post an
example of the multiple calls so we don't have to bug you about it
again?
------------------------------------------------------------------------
---
If you want failure_route to be evoked only for some calls, then
set t_on_failure_route for such. You already do so in your script,
don't you?
There is other problem though -- the failure_route logic for VM should
be different
from that in route block -- you can't create transaction state two times
(first time with t_relay, second time with t_newtran). SER will
certainly
complain with some error message in your logs.
I will introduce some new command which hides details of transaction
processing
from script writers and can be used from both route[] and
failure_route[].
(I didn't think of it before since I used voicemail on some other
machine
than proxy server.)
