Summary:                    [patch] DNS SRV lookups causing re-registration
problems
Description: 
SIP peer uses DNS SRV records which list multiple entries for
_sip._udp.domain.  

Asterisk is selecting one and successfully registering with it.  When
attempting to re-register, Asterisk is not selecting the same host. 
Instead it is ALWAYS selecting another host, sending seven SIP REGISTER
requests to it, then failing over to the next (correct) host, at which
point the re-register succeeds.  However, this process exceeds the
registration expiry and the registration is timing out on every
re-registration cycle.

Peer in question is callcentric.com.

No problem. Thank you for continuing to follow up even though you do not
need the patch supplied.

I am going to see what putnopvut thinks in terms of this being a bug, and
whether this should be committed or not.

I will probably still need to test the patch to see if it has any adverse
affects on the callcentric account to make sure it doesn't break things :)
