User's Manual
Enables the device to unregister all user Accounts that were registered
with the device, upon a device reset. During device start-up, each
Account sends a REGISTER message (containing "Contact: *") to
unregister all contact URIs belonging to its Address-of-Record (AOR). A
second after they are unregistered, the device re-registers the Account.

[0] = (Default) Disable

[1] = Enable
To configure Accounts, see Configuring Registration Accounts on page
377.
Disables the sending of SIP 503 (Service Unavailable) responses upon
receipt of new SIP dialog-initiating requests when the device's CPU is
overloaded and thus, unable to accept and process new SIP messages.

[0] Disable = No SIP 503 response is sent when CPU overloaded.

[1] Enable (default) = SIP 503 response is sent when CPU overloaded.

Note: Even if the parameter is disabled (i.e., 503 is not sent), the
device still discards the new SIP dialog-initiating requests when the
CPU is overloaded.
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 received in the Event
header.

[0] Disable (default)

[1] Enable
The action depends on the Event header value:

'check-sync;reboot=false': triggers the regular Automatic Update
feature (if Automatic Update has been enabled on the device)

'check-sync;reboot=true': triggers a device reset
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
