Dear All,

Hopefully I'll be able to get some help here on re-INVITE in the failure route. For example I have a couple of PSTN gateway options. I'd like to try them by priorities. In case the one with top priority couldn't go through(e.g. returned 5XX on INVITE), I'd like to re-INVITE through another provider in the failure route. Not sure what I should do for such cases. Thanks.

Regards,
Jay
