Configuration looked like this:

DHCP leases came from the Bell modem. Phones were configured to use

Seems like a strange network setup. You didn't state if NAT was
involved here. Are you taking multiple addresses (modem configured in
bridge mode)?
Regardless - it seems odd to configure an external DNS on the phones.
The external DNS will likely not have the internal address for the
Asterisk server. The resolver lookups may round robin between the DNS
entries on the phones, rather than a fall-though situation.
Just a couple of ideas....
