Call Admission Control specification

Session Manager supports converged voice and video bandwidth management with Avaya Aura® System Manager centralized administration and control. You can administer bandwidth allocations between voice and multimedia traffic, and allow voice to use bandwidth from unused video allocations when network conditions require the bandwidth. Session Manager intercepts each SIP request for service, examines the SIP message for the requested bandwidth, and allocates the actual bandwidth requested and accepted. However, Session Manager denies as well as downspeeds calls if the bandwidth allocation is exceeded. In addition, Session Manager can automatically downspeed video calls to the bandwidth available and enable video calls to complete at lower bandwidths.
Session Manager provides advanced control of video and multimedia bandwidth allocation. Administrators can configure:
  • The maximum allowed bandwidth for a multimedia call with separate controls for inter-location (where resources are scarce) and intra-location (where more bandwidth is generally available so higher quality can be allowed) on a per-location basis.
  • The minimum level to downspeed video bandwidth by location to ensure a level of video quality.
Administrators can view the current bandwidth usage and the number of calls for accurate management.
