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 _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
