CIA/3web/Distributel VoIP down?

First email alert came in at 3:00pm showing the ATA lost registration. reboot of the ATA and clear of the firewall's connection states for the VoIP adapater's IP didn't help (as it has many times in the past).

Looking at a tcpdump on the firewall, I see outbound SIP/5060 registration packets and no responses:

15:53:25.925566 IP .5060 > 206.80.250.126.5060: SIP, length: 584
15:53:26.925623 IP .5060 > 206.80.250.126.5060: SIP, length: 584
15:53:28.925493 IP .5060 > 206.80.250.126.5060: SIP, length: 584
15:53:32.925201 IP .5060 > 206.80.250.126.5060: SIP, length: 584
15:53:36.925068 IP .5060 > 206.80.250.126.5060: SIP, length: 584

whois of that destination IP:

voip-mtrl1.cia.com 206.80.240.0/20

more data:

3web said something was blocking the account but they removed that. the problem persists. they said this should be working.

further digging on my side:
if i connect through bell, it works.
if i connect through teksavvy, it doesn't work

what doesn't work? SIP registration. on teksavvy there's never a response from 3web's server. as soon as i switch over to bell, i get responses right away and everything works.

any ideas?
