[cisco-voip] Audio Quality on Latest Gen Phones

[Ryan Ratliff]

Lots of phones have supported the wideband codec for a while now.   
The 79x2/5 phones have a wideband handset that actually gets you  
higher quality audio coming from the DSPs into your ear.  We've had  
positive and negative feedback on the new handsets and it comes down  
to if you don't like it, swap the wideband handset for an older style  
one.   You can tell them apart by looking at the mic end of the  
handset.  The older ones just have a "button" with a circle cut out  
around it.  The new ones have a set of concentric circles cut out  
with plastic lines cutting through them.   It's very obvious when you  
look at them side by side.

The 7941s also supported wideband, so the difference must be  
something beyond that. What codec are you using phone to phone with  
the 7941s versus the 7942s?

  Just got in some 79x2 and 79x5 phones. On all of these sets when  
calling Unity or phone to phone the audio sounds very different then  
the previous phones. The only way I can describe it is as very  
"bassy". If you swap in a handset from an older phone such as a 7941  
it sound "normal".

  Anybody else run into this? I think I would get a lot of complaints  
from my users if I roll these out. The audio just sounds wrong.

Thanks!
Steve
