Gateway services are the mechanism that allows IP network endpoints to choose
the type of connection they want to establish with a terminal or telephone on a
circuit-switched network. A LifeSize Gateway service defines the maximum bit
rate for each channel, the media content of the stream (voice or data), and the
mode of the call (restricted or non-restricted).
A service prefix identifies a service. The service prefix is an identifier string that
can have up to 31 characters. Valid characters are 0 to 9, pound (#), asterisk (*),
or comma (,). You access a service by dialing the service prefix before the phone
number of the destination. For example, 9* would be identified by the LifeSize
Gateway as a service prefix if you dialed 9*5673994.
Note If the Ignore caller bearer rate and force service rate setting in the
Advanced section of the Settings tab is selected, a service uses the defined bit
rate. If the Ignore caller bearer rate and force service rate setting is deselected,
the bit rate defined in the service serves as the maximum limit for the service.
The LifeSize Gateway has two types of services: default and user-defined.
Default services come pre-configured on the LifeSize Gateway. User-defined
services are services that you can define at any time using the LifeSize Gateway
interface. Upon registration with a gatekeeper, the LifeSize Gateway provides
the gatekeeper with a list of LifeSize Gateway services.
