[Users] t_relay does not follow RFC3263 "Locating SIP Servers"

[Daniel-Constantin Mierla]

Hello,

it should do SRV lookup and if it gets some RR it uses them. Try to 
watch the DSN traffic for you sip server with "ngrep port 53".

Also you can check with "host -t srv _sip._udp.fenet2.at" if the DNS 
server returns correctly the SRV records. Only in the case no SRV record 
is returned, the openser tries normal DNS lookup.

Another option is to set openser in debug mode (log_stderror=yes and 
debug=7) and watch the messages or send them to me to analyze them.
