Low-bandwidth Connections
You can configure a telephone to operate in lower-bandwidth
environments such as a single B channel of a BRI ISDN line or other links
with bandwidth as low as 56 Kbps.
The preferred method for enabling this is to select G729 audio,
■
forcing the device to use lower-bandwidth audio when
communicating with other system devices.
Alternatively, you can configure the telephone as a low-bandwidth
■
device when you configure the device parameters.You can reduce
bandwidth by disabling some of the NBX system's internal status
messages and features that require multicast data traffic including
(examples: paging, conferencing, and music-on-hold).
You can also connect an NBX Telephone to the system over a broadband
connection and that is not considered a low bandwidth connection. See
the NBX Administer's Guide for information about connecting a remote
telephone.
