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 188.8.131.52 ip unless it is unavailable for some reason. If unavailable it will give you 184.108.40.206. If you do a standard DNS lookup if will 50% of the time 220.127.116.11 and the rest 18.104.22.168.
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.
