Hi,

Would someone please share DT900 firmware 05.03.04.99 or later ? We are migrating NEC phones to a Yeastar pseries system and this version is required.
email: erik@allesi.ca

Thanks,
 
Only do this if you want a really poor experience with the Yeastar. The NEC handsets running standard sip are really dumb and at best are only equivalent to a very old analogue phone as none of the buttons are programmable (like having an analogue phone with no speed dial buttons). If you are trying to save costs, look for second hand Yeastar phones on ebay or something like that. Even a basic Yeastar will give you more than a DT900 and you won't keep getting asked to program keys that can't be.

So you mean the autoprovisioning doesn't work with NEC phones ? ;) The function keys will not load? (on an updated pseries 560 for example)
