There are two ways to set admission control:
• Determine the expected number of simultaneous intra-site calls for a site, and
multiply this number by the bandwidth required for each call for your selected
inter-site encoding.
When admission control is set this way, calls routing between sites will be blocked
if placing the call would exceed the number of calls supported by the configured
bandwidth.
• Set admission control to the total bandwidth available to the site.
To determine the number of calls that will be supported, divide the total
bandwidth by the bandwidth needed per call for ShoreTel inter-site encoding.
When admission control is set this way, ShoreTel 6.1 will consume up to the entire
bandwidth for voice, reducing the chances of a blocked call. When the maximum
bandwidth is used because the system is accommodating the maximum number of
phone calls, bandwidth for data will be a lower priority, which impacts the
performance of data transfers.
For more information about ShoreTel’s Admission Control feature, see “Admission
Control in the Wide Area Network” on page 9-10.
Setting Admission Control
The Admission Control Bandwidth parameters are set in the Site edit page of
ShoreWare Director. For information on setting this parameter, see Chapter 3,
“Configuring Sites” in the ShoreTel 6 Administration Guide.
