There are audio and echo issues 
on the headset.

Possible issues include:

Echo on external calls 
through a gateway. 

Internal calls (no gateway),

SoundPoint IP 300 and/or 500 
behave incorrectly or do not 
display new features.

New features are not supported 
on the SoundPoint IP 300 and 
500 and the configuration files 
have not been correctly modified. 
The SoundPoint IP 300 and 500 
will not ‘understand’ the new 
configuration parameters, and 
will attempt to load the new 
application.

The attempt to load the new application 
will fail since there is no 300/500 image 
contained within the sip.ld file, so the 
phone will continue on and run the current 
version of application that it has in 
memory. It will however use the new 
configuration files. Refer to
