Hi Tim,
if you have records with the same priority, openser will take the first
one as returned by the DNS server - it does not do a load balancing -
maybe the DNS server should do.

Hi,
The OpenSER is performing an SRV lookup which returns the following record info:
;; QUESTION SECTION:
;_sip._udp.aimcidfilter.com. IN SRV
;; ANSWER SECTION:
_sip._udp.aimcidfilter.com. 180 IN SRV 1 50 5061 spinner.eng.rr.com.
_sip._udp.aimcidfilter.com. 180 IN SRV 1 50 5061 bart.eng.rr.com.
_sip._udp.aimcidfilter.com. 180 IN SRV 2 50 5061 homer.eng.rr.com.
_sip._udp.aimcidfilter.com. 180 IN SRV 2 50 5061 crunch.eng.rr.com.
As you can see, the weighting for the two priority "1" endpoints is
50/50 which indicates that the load should be distributed evenly
between them. But when I run my test, it consistently sends 75% to
spinner.eng.rr.com and 25% to bart.eng.rr.com.
Any ideas?
