Feature Description

Description
Name given to the port expander. During Plug ‘n’ Play installation, the
Description is set to the port expander MAC address. Allworx
recommends changing it to something more meaningful to the site or
configuration.
Codec Preference Order
Set the preferred codec order for the port expander. The codec is the
method of encoding/decoding the audio sent and received. The two
possible codec are G.711 and G.729A. G.711 preserves voice quality but
takes more bandwidth. G.729A takes less bandwidth but reduces voice
quality.
Note: This setting defines the order of codec selection. The system does
not support all codec for all call types (for example, accessing the server
Auto Attendant requires G.711). The port expander attempts to use the
first choice but uses whichever required codec to support calls.
