IP-PBX Call Policy

Endpoints are assigned to pools that establishdevice capabilities:

Max bandwidth for calls placed

Allowed calling destinations, time specific policiesAllowed incoming call sources

Endpoints are assigned to locations that are usedfor inter-location calls

Inter-location calls are subject to bandwidth maximumsInter-location aggregate bandwidth is used for CACto allow a call, reroute through Gateway, or given abusy signal

Summary

The technical components are common for rich mediaconferencing networksMCU, gateways, call control, endpoints and applications

The components that are required depend heavily on the

applications and deployment architecture Video telephony builds on existing videoconferencing

solutions extending IP-PBX functionality to the end user

Rich-media conferencing consolidates the audio, video andweb conferencing solutions

Common call control and gateways allows these applicationsto be integrated extending the solution and benefits tomultiple users throughout the organization
