I agree..   well there is DSS if the phone is idle..  but there is no way for 
the button to have states//  like with aastra if a BLF is in the ringing state 
you can  apply the directed call pickup code to the button so it answers the 
call ringing on that button..  the Digium phone can just dial the extension 
number...   there is no one button transfer  to a BLF keey either..  alas if 
you are on acall and want to transfer a call to a DSS key you have to press 
transfer.. press the key, press transfer again...   the Aastras allow you to 
set it up as a Blind transfer key  or where you press the key, wait for the 
person to answer and press transfer again... 

the only way i was able to get single key Park with BLF t owork is because of a 
loophole in asterisk  that allows a park pickup to fall through on the dialplan 
if there is no call parked which the fallthrough is a "park" command..  
otherwise these phones cant dial something different on a DSS / BLF based on 
the state of the button...

some items on the Digium phone will update config without a phone reboot, 
others wont, but there is no documentation on which items can be changed and 
which cannot..  I would expect SIP items  to not reboot the phone, but changing 
ringtone options caused the phone to reboot..

I also think in some ways the phones are TOO tied to asterisk  when using the 
DPMA..  with aastras I can used a completely third party script to PUSH  XML 
data to the phones..  so things like BLFs, ringers, speed dials, etc can be 
Pushed to the phones without any involvement from asterisk..  

the Digium phones, changing contacts requires I first build out the contacts 
(BLF), requires I first build out the contacts XML file..  then issue a 
reconfigure command from the asterisk CLI (or AMI)  to tell the phone to go get 
it...  to change a ring-tone, requires, modification to the digium  phones CONF 
file, so if not using realtime it would require a module reload on the DPMA, 
then issue a reconfigure command to the phone..  likely resulting in a phone 
reboot..

the audio quality of the phones seems pretty good..  probably not as good as 
polycom  but surely better speaker quality on the D50 and D70  than the aastra 
6731 or 6755..  the speaker quality on the aastra 6757  seems pretty good...


all in all I think Digium just wanted to get these phones on the market 
quickly..  ive been told there are "great enhancements" coming for the DSS / 
BLF keys, in my opinion the only reason to Buy the D50 / D70  over say a 
polycom ot Yealink  is because of the DSS / BLF  buttons.. esp the D70 with 
self labelling keys..

BLF without DSS is next to useless.
What were they thinking? Or were they thinking?

Too many engineers don't really know what users want and need in the
    real world.
Users want buttons and lights!
Having to reboot a phone is inexcusable
