[SR-Users] modify FROM field in the "failure_route" block

[Carsten Bock]

Hi,

did you install it from source? If yes, you can simply add the
"BRANCH_ROUTE" to allowed routes in OpenSER 1.3, that should work, i
used it that way many years ago... (i think you need to change the
module another place too).
I strongly recommend you update your OpenSER to a more recent
Kamailio, then you won't have that problem at all.

Kind regards,
Carsten
