[Serusers] DNS SRV

[samuel]

First of all, I gues you are using rewriteXX functions because it's a
test, isn't it?? I would say you do not have to rewrite neither the
domain not the port, using just t_relay will make SER to perform a DNS
query for the domain present in the destination uri's domain. Try the
basic config to see if it works...

If it does not work:
If your problem is that SER is not starting, please post the
apropriate debug information.
If SER is starting but it does not resolve the domain name, please
post the output of the files /etc/resolv.conf and /etc/hosts.
please execute:
dig NAPTR sip.inogen.com from the SER box and post the output.

Hope you solve it soon!
Samuel.
