[Serusers] DNS SRV

Hi,

I am a newbie setting up the DNS SRV, below is my the DNS setting:

sip1 10    IN A            192.168.1.111
sip2 10    IN A            192.168.1.112

sip.inogen.com. IN NAPTR 0 0 "s" "SIPS+D2T" "" _sips._tcp.sip.inogen.com.
sip.inogen.com. IN NAPTR 1 0 "s" "SIP+D2T" "" _sip._tcp.sip.inogen.com.
sip.inogen.com. IN NAPTR 2 0 "s" "SIP+D2U" "" _sip._udp.sip.inogen.com.

_sips._tcp.sip.inogen.com. 10 IN SRV 0 0 5060 sip1.sip.inogen.com.
_sips._tcp.sip.inogen.com. 10 IN SRV 0 0 5060 sip2.sip.inogen.com.

_sip._udp.sip.inogen.com. 10 IN SRV 100 10 5060 sip1.sip.inogen.com.
_sip._udp.sip.inogen.com. 10 IN SRV 100 10 5060 sip2.sip.inogen.com.

_sip._tcp.sip.inogen.com. 10 IN SRV 300 10 5060 sip1.sip.inogen.com.
_sip._tcp.sip.inogen.com. 10 IN SRV 300 10 5060 sip2.sip.inogen.com.


And I try to do this in the ser config:
  rewritehost("sip.inogen.com");
  rewriteport("");

  t_on_reply("1");

  if(!t_relay()){
     sl_reply_error();
     log(1,"SER LOG: can't relay");
  }

But I couldn't get SER to start up successfully as it could not resolve the
host name sip.inogen.com, can you help to pinpoint how shall I set the DNS
configuration? Thanks in advance.

Regards,
Chia

In the stable version SER will not cache DNS results and will depend
on the underlying resolver.
However, this week there was a post in the ser-devel list regarding
DNS and caching (in adition to great DNS failover :D).

Try to look for it if you are using CVS HEAD SER version.
