I've setup some SRV records to test failover between a few servers.
$ dig _sip._udp.testing-sip.giggsey.net SRV
;; ANSWER SECTION: _sip._udp.testing-sip.giggsey.net. 371 IN SRV 10 0 5060 testing-sip-real.giggsey.net. _sip._udp.testing-sip.giggsey.net. 371 IN SRV 0 0 5080 testing-sip-fake.giggsey.net.
testing-sip-fake is a FreeSWITCH box, configured to hangup every inbound call with 503: NETWORK_OUT_OF_ORDER.
testing-sip-real will accept traffic from this server, and actually connect to something.
When I make a call via FreeSWITCH (latest master), it sends the INVITE to testing-sip-fake, which responds correctly. FreeSWITCH does not ACK the 503, but sends the INVITE to testing-sip-real.
testing-sip-real responds with a 200, but FreeSWITCH sends the ACK to testing-sip-fake.
