T48G - Skype for Business Online

[standardcomp]

Well I have just discovered this thread and I thought I'd contribute.
Step 1. Google an IP phone that will work with skype.
Step 2. Buy Yealink phone, find that the stock firmware has no UC settings.
Step 3. Download the UC firmware from http://bit.ly/1Wct9We "SIP-T48G (35.7.0.50) UC Edition"
Step 4. With firmware installed find that 'license' is needed so I follow instructions here: http://bit.ly/22KioKH
Step 5. License installed, can't connect to server..
Step 6. Email Support, get sent different firmware (T48-35.8.0.14.rom)
Step 7. I find this (this) thread that says the firmware won't be out until it's Q2 now.. fuuuu
Step 8. Karl from yealink tells me that the firmware should work, I need to factory reset and disable trusted certifcates under settings.
Step 9. I can now make Skype calls using skype for business office 365. SFC O365 Huzzah!
