Single Registration
The SoundStation IP 7000 phone supports a single registration.
When the phone is unable to register with the call control server, the icon 
 is shown (outline). Once the phone is able to register, the icon 
 is 
shown (solid).
Audio Codecs
The following table summarizes the SoundStation IP 7000 phone’s new audio 
codec support:
Configuration changes can performed centrally at the boot server:

Note
The network bandwidth necessary to send the encoded voice is typically 5-10% 
(confirm number) higher than the encoded bit rate due to packetization overhead. 
For example, a G.722.1C call at 48kbps consumes 5xkbps of network bandwidth.
