<br>
According to the RFC, in RR header can be IP or FQDN
(any kind of SIP URI). Even more, the best practice is
to actually use IPs in RR to be 100% sure that the
following requests to hit exactly the same box (if using
FQDN, subject to DNS resolving, a different IP may be
lookup up later).<br>
<br>
If you really want to put an IP there, use the
record_route_preset() function:<br>

name, but in the OpenSIPS setup the logs state <i>"Resolving
