9.15 Computing Admission Control Bandwidth
This section discusses how to compute the admission control bandwidth for the site you
are configuring on the Site edit pageā€”that is, the appropriate value for the Admission
Control Bandwidth parameter. If you want to determine the admission control bandwidth
for your site and the information is not available in this section, use one of the following
To determine the admission control bandwidth:
Bandwidth = (# of calls) x (bandwidth/call)
To determine the number of calls supported with a specific admission control
bandwidth value:
# of calls = (admission control bandwidth) / (bandwidth/call)
ShoreTel automatically negotiates the proper voice encoder at call setup. For calls between
sites, the call control software requests the voice encoder based on what is selected for
inter-site voice encoding as defined on the Call Control Options edit page. The call control
software will then make sure both endpoints on the call can support the requested voice
For instance, for G.729a voice encoding to be used between two sites, the inter-site voice
encoding must be set to G.729a and the ShoreGear voice switches at each end of the call
must be G.729a-capable.
