Hi, All!

I found another domain name to test and got the right answer.

$ ./a.exe
Minires: search "_sip._udp.yalin.tw" type 33
Minires: /etc/resolv.conf: OK
Minires: resolv.conf nameserver 192.168.1.1
Minires: server "192.168.1.1"
Minires: key SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Minires: value SearchList, error 0 (Windows), size 1
Minires: getdomainname ""
Minires: query "_sip._udp.yalin.tw" type 33
Minires: open sockfd 3: OK
Minires: sendto: server 0101a8c0 sockfd 3 OK
Minires: answer 188 from 0101a8c0. Error 0. Count 1.
go in
dump answer
Host name from SRV record is sip.yalin.tw
Port from SRV record is 5060

Which is the same as using dig on Linux
[ypwang AT G-M ypwang]$ dig SRV _sip._udp.yalin.tw
; <<>> DiG 9.2.2 <<>> SRV _sip._udp.yalin.tw

It seems that the orginal site "_rvp._tcp.lucent.com" has no SRV record.

Cheers,
Andy
