Separation of Bearer and Signaling (SBS)

In an Avaya IP Telephony system, call signaling and bearer traffic may be routed over separate
paths. This is useful for a remote branch office with only limited WAN bandwidth back to
headquarters. Call signaling traffic can be routed across the WAN, while bearer traffic is sent
over the PSTN.

Multi-location

Communication Manager 2.2 allows a Linux-based media server located in one country to
control gateways located across national borders and provide appropriate country-specific
tones and features. Specifically, these features include the following:
A-law & Mu-law Companding
Call Progress Tone Generation
Loss Plan
Analog line board parameters
