[OpenSIPS-Users] DNS SRV records

currently using opensips-1.4.2-tls
the dns is indeed valid. I've checked it against other nameservers on the
net other than our provider's name server
there's nothing fishy in my config file either. Pretty straight forward
routing. As you can see in the ngrep cap below, the SRV record is returning
the A records for the domains in it.
Any help is always appreciated :) Thanks
Alex
