Bonded DSL, DDR2200, and VOIP

Is anyone successfully using this combination? I found one topic from a year ago with a similar problem, but no solution reported and the OP hasn't been back since then.

We tried setting up some VOIP phones today over a bonded DSL connection with a DDR2200 router. This is a Prism setup, without the TV service activated. The internet works and the modem stats are good on both pairs. It's a 20/2 connection. I get 19.5 down and 1.5 up on various speed tests. The DNS resolves and the phones download their config files and images, but are unable to register with the VOIP server.

I found the password and was able to login as admin. We disabled the SIP ALG, and tried setting up port forwarding. The only suggestion CL Support offered was to put the modem in bridge mode and try a separate router. We didn't have another router at the site, so that's the only thing we didn't try.

Any comments or suggestions?
