Parameter Description
Select the VoIP Send SIP 100 Trying checkbox to send "SIP 100-trying"
messages to a call originator to indicate that the call is proceeding. This is
a useful option when the SIP invite is directed through many servers
before reaching the controller.
VoIP Disconnect Extra Call In the VoIP Call Admission Control (CAC) profile, you can limit the number
of active voice calls allowed on a radio. This feature is disabled by default.
When you enable the disconnect extra call feature, the system monitors
the number of active voice calls, and if the defined threshold is reached,
any new calls are disconnected. The AP denies association requests from
a device that is on call.
To enable this feature, select the VoIP Disconnect Extra Call checkbox.
You also need to enable call admission control in this profile.
VOIP TSPEC Enforcement A WMM client can send a Traffic Specification (TSPEC) signaling request
to the AP before sending traffic of a specific AC type, such as voice. You
can configure the controller so that the TSPEC signaling request from a
client is ignored if the underlying voice call is not active. This feature is
disabled by default. If you enable this feature, you can also configure the
time duration within which the station should start the voice call after
sending the TSPEC request (the default is one second).
Select the VoIP TSPEC Enforcement checkbox to validate TSPEC
requests for CAC.
VOIP TSPEC Enforcement
Period
Select the maximum time, in seconds, for the station to start the call after
