I'm using SEMS sbc dns srv rerouting + uac_auth.
I have domain( onat.edu.ua ) with 2 srv records.
>dig -t SRV _sip._udp.onat.edu.ua
;; ANSWER SECTION:
_sip._udp.onat.edu.ua. 600 IN SRV 0 0 5060 io.onat.edu.ua.
_sip._udp.onat.edu.ua. 600 IN SRV 0 0 5060 astx.onat.edu.ua.
also server io.onat.edu.ua which doesn't respond , (server doesn't
work special for testing)
If SEMS send requests to astx.onat.edu.ua firstly, I have no problems
with it.
But if io.on:at.edu.ua is selected for first request and if
authorizations is turned on, we can see next

After few retransmits Invite with Proxy-Authorization finally was
finally sent to working gateway
Maybe it have to send invite to gateway, which has respond with 470
