The srv lookups are weighted. When you try to register and do a SRV look up to port 0 it will return to you the 18.104.22.168 ip unless it is unavailable for some reason. If unavailable it will give you 22.214.171.124. If you do a standard DNS lookup if will 50% of the time 126.96.36.199 and the rest 188.8.131.52.
They say it is an issue with the way the IP Office looks up the SRV record for the FQDN. I say this is bull as other customers to the same provider have not complained with the same IP Office settings. Anyone else see anything like this before.
