Thanks for confirming, I will open a ticket as well (on behalf of my father). I see BYOD users complaining about the registration issue over on DSL reports. I've confirmed this is not occurring on their SIP servers for provisioned users (sip-central01).

I'm assuming this is being worked by Tier 2 support. Would you happen to have the name of the Voipo tech working your support ticket?

FYI: I've complained to Tim before about their lack of oversight on these BYOD servers before, so this is just another classic example.
