T48G SIP to SfB

[jvoros]

You can download the SfB firmware from yealinks support site and log in to the phones via the web gui and click 'Upgrade'

Then they have a website you go to to get a 'license' file to upload to the devices which is based on the MAC address.

minimal other feature changes are needed and of course the user needs to log in with their AD credentials. Only gotcha is ensuring the username and UPN are known so the two 'user' fields are entered correctly.

We've deployed ~40 phones on SFB and so far so good with minor grievances regarding features.

The one major thing we had to work out what a dial plan that isn't on the phones but received through SFB server. These phones require things like +1 in front of each line or it wont dial and for the most part uses the addressbook/contact lists to dial people. So if you had 4 or 5 digit dial set up, only with a dial plan will it work. They could use some improvements here (for example if I put in 10 numbers and press 'call', it should just dial instead of doing a lookup or forcing the + key (which isnt a key that is available on the dial pad).
