Control
page.
VoIP High-capacity
Threshold (0-100%)
20 Specifies the threshold that defines high-capacity VoIP. This field is a
percentage of entire bandwidth.
VoIP Send SIP 100
Trying
No The SIP invite call setup message is time-sensitive, as the originator
retries the call as quickly as possible if it does not proceed. You can direct
the controller to immediately reply to the call originator with a “SIP 100 -
trying” message to indicate that the call is proceeding and to avoid a
possible timeout. This is useful in conditions where the SIP invite may be
redirected through a number of servers before reaching the controller.
Enable or disable SIP call setup keepalive with this field.
VoIP Disconnect
Extra Call
No 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 the disconnect extra call feature is enabled, 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.
Enable or disable this feature in this field. You also need to enable call
admission control, which is disabled by default, in this profile.
VoIP TSPEC
Enforcement
No 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
number of seconds that a client must wait to start the call after sending
the TSPEC request (the default is one second).
You enable TSPEC signaling enforcement in the VoIP Call Admission
Control profile. This field enables or disables TSPEC Enforcement.
VoIP TSPEC
Enforcement Period
(0-100)
1 When TSPEC is enabled, this field sets the number of seconds that a
client must wait to start the call after sending the TSPEC request.
VoIP Drop SIP Invite
and Send Status
Code (Client)
486 The SIP invite call setup message is time-sensitive, as the originator
retries the call as quickly as possible if it does not proceed. You can direct
the controller to immediately reply to the call originator with a “SIP 100 -
trying” message to indicate that the call is proceeding and to avoid a
possible timeout. This is useful in conditions where the SIP invite may be
redirected through a number of servers before reaching the controller.
Use this field to enable or disable SIP call setup keepalive in the VoIP Call
Admission Control profile for the client.
VoIP Drop SIP Invite
and Send Status
Code (Server)
486 The SIP invite call setup message is time-sensitive, as the originator
retries the call as quickly as possible if it does not proceed. You can direct
the controller to immediately reply to the call originator with a “SIP 100 -
trying” message to indicate that the call is proceeding and to avoid a
possible timeout. This is useful in conditions where the SIP invite may be
redirected through a number of servers before reaching the controller.
Use this field to enable or disable SIP call setup keepalive in the VoIP Call
Admission Control profile for the server.
