At my old address, I was running Virgin cable broadband with my 2820Vn and my SIP account for Draytel always registered with no problems and VOIP was working perfectly. I've just moved, and can't get Virgin, so have switched to Sky ADSL and now the SIP account won't register for love nor money. I'm pretty sure that the problem isn't that Sky is blocking the ports for VOIP as I've downloaded X-Lite software and that will connect to my Draytel account no problems.

Has anyone else had any issues with a Draytek 2820Vn not being able to register SIP accounts using Sky ADSL? I've tried setting the SIP account to register specifically via WAN1, and also to "Auto", but nothing seems to solve the issue, it just doesn't want to register. I've updated to the latest 3.3.5 firmware (was running the 3.3.4 firmware from last October), but that also has not helped solve the situation.

I'm about to try some other SIP accounts from different providers to check if the problem is specifically related to Draytel, but I can't imagine that it is.

Any help/advice much appreciated!

I've checked the voip logs, and gotten the following (with relevant private info altered of course!):

So it's able to contact the sip servers, but then not authenticating, either for my draytel account, or for another sipgate account I set up a while ago to check issues weren't with one account!

I can log into these accounts fine with the same username/password etc... using x-lite, so something is wrong on the draytek end?!

Ok, finally managed to solve the problem - it seems that inputing the MAC of the sky router into the setup for WAN1 has solved the problem. Slightly strange since the internet connection etc... was already there, but hey ho, for whatever reason, it's now working!

Panic over!
