Summary:                    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.
