[OpenSIPS-Users] Record-Route when failed proxy

Hello Damien,

If you put IPs in RR, there is no way (AFAIK) to make the end point to
fail to a different IP.

Theoretically, the only solution is to use a FQDN into RR, but never
tried into real life - it should work - could you detail the kind of
problems you had when doing this ?

Best regards,

Bogdan-Andrei Iancu
OpenSIPS Founder and Developer
