Upgraded Yealink f/w 2.70.0.103; dialcodes different?

I upgraded a bunch of my Yealink T28's to firmware 2.70.0.103. I previously had 2.61.0.80 firmware. I guess it treats the BLF and transfers differently now? Before I had it set to type BLF; Value=extension (e.g. 2200); Extension=*20*2200. When you press that blf it would dial *20*22002200.

For a quick fix I went in to a each phone and removed the extension after the *20* so it just has the extension in the "Value" and *20* in the "Extension". Backwards, but a quick fix!

Do I need to change something elsewhere to get these phones to provision correctly?

When I upgraded the firmware I went in to each phones gui and went to the upgrade tab > select and upgrade firmware. It appears that I should have rest the phone to factory first (as someone indicated in another of my threads) THEN performed the firmware upgrade.
