Hi All,

I am facing problem to get SER to do a SRV lookup. I have the following scenario…

Step 1:

SIP UA1 registers with SER (testdomain.com) with contact address user@testdomain.com

SIP UA2 registers with SER (testdomain.com) with contact address user@testdomain.com

Step 2:

SIP UA3 calls user@testdomain.com

Problem

I would expect SER to do a DNS SRV lookup on testdomain.com and get sip1.testdomain.com and sip2.testdomain.com. Unfortunately, SER only does A and AAAA query. (verified via ethereal) and does not do SRV lookup. How can I make it do SRV lookup ? I am using the default ser.cfg file.

DNS entries

_sip._udp.testdomain.com.                     3600     IN         SRV     0          1          5060     sip1.testdomain.com.

_sip._udp.testdomain.com.                     3600     IN         SRV     0          1          5060     sip2.testdomain.com.

I am trying to do load balancing but the SRV lookup failure has got me stuck. Any pointers would be really appreciated.

Thanks,

Chetan
