Hello,

the proper way to change it is inside a branch_route -- before relaying inside the failure_route, arm a branch route with t_on_branch() and there to the From update.

Cheers,
Daniel

Hello,

My sip vendor sends me a 403 error when the caller id (CLI) sent is not valid.

I would like to set up a failure route to capture that 403 and set up a default CLI.

I tried to use a uac_replace_from() in a failure route but I get:

"Command cannot be used in the block"

Does anyone know how can I change the CLI in a failure route how how can achieve the default CLI?

Thank you
