Enables the device to send SIP 408 responses (Request Timeout)
upon receipt of non-INVITE transactions. Disabling this response
complies with RFC 4320/4321. By default, and in certain
circumstances such as a timeout expiry, the device sends a SIP 408
Request Timeout in response to non-INVITE requests (e.g.,
REGISTER).
■ [0] Disable = SIP 408 response is not sent upon receipt of non-
INVITE messages (to comply with RFC 4320).
■ [1] Enable = (Default) SIP 408 response is sent upon receipt of
non-INVITE messages, if necessary.
Enables a specific device action upon the receipt of a SIP NOTIFY
request, where the action depends on the value in the Event header.
■ [0] Disable (default)
■ [1] Enable
The action depends on the Event header value:
■ "Event: check-sync;reboot=false": Triggers the regular
Automatic Update feature (if Automatic Update has been
enabled on the device).
■ "Event: check-sync;reboot=true": Triggers a device reset.
■ "Event: soft-sync": Triggers the device to disconnect all current
calls.
Note: The Event header value is proprietary to AudioCodes.
Defines the maximum size (in Kbytes) for each SIP message that
can be sent over the network. The device rejects messages
exceeding this user-defined size.
The valid value range is 1 to 100. The default is 100.
Determines whether the device sends SIP responses to the UDP
port from where SIP requests are received even if the 'rport'
parameter is not present in the SIP Via header.
■ [0] = (Default) Disabled. The device sends the SIP response to
the UDP port defined in the Via header. If the Via header
contains the 'rport' parameter, the response is sent to the UDP
port from where the SIP request is received.
■ [1] = Enabled. SIP responses are sent to the UDP port from
where SIP requests are received even if the 'rport' parameter is
not present in the Via header.
Enables or disables the device to accept or reject SIP CANCEL
requests received after the receipt of a 200 OK in response to an
INVITE (i.e., call established). According to the SIP standard, a
CANCEL can be sent only during the INVITE transaction (before
200 OK), and once a 200 OK response is received the call can be
rejected only by a BYE request.
■ [0] Disable = (Default) Accepts a CANCEL request received
during the INVITE transaction by sending a 200 OK response
and terminates the call session.
