I tried to respond to MadMax's thread here:
»[Internet] Bell Fibe and Sagecom Connection Hub
But it's too old. I just wanted to put in a quick follow up..
I've spent the last week trying to get 4 Polycom 335s online with one of these modems, and it couldn't be done.
It seems that the DHCP server (or more) in the Bell modem is buggy, and plugging in a phone causes it to not work, either complaining that the network link is down, or that the DHCP server was unreachable.
After that, you can't access the web interface on the Bell modem anymore, and in some cases, the whole internet connection drops out, and the modem has to be restarted (maybe several times) to get it back online.
Bell came and replaced the modem, I wanted to test if the issue was resolved, but the very unprofessional Bell technician refused to try plugging the phone in, so I could show him the problem, and he kept claiming that it was the phones' fault that they didn't work, and then hung up on me.
(I have that call recorded for anyone who wants to listen to a rude unprofessional Bell technician, or I suppose you could just call 310 SURF for that).
The replacement modem exhibited exactly the same behaviour.. plug in a Polycom, and bam, Bell modem crashes.
In the end the resolution was to install a Dlink router between the modem and the phone, using the Dlink's DHCP server to provide an IP to the phone, and then configure a static lease in the Bell modem for the Dlink router, and DMZ all the traffic to that IP.
