User's Manual

- NO - turns off the AUTO_UPDATE feature.
Note:
If the IP Deskphone encounters any Major or Critical error in memory during the Auto
update process, the IP Deskphone reboots based on the recovery level configured.
• AUTO_UPDATE_TIME [x] — is the actual time in seconds, starting from midnight, before
an automatic update occurs. Each IP Deskphone adds random numbers to the time
specified by this command so that every IP Deskphone does not try to access the
provisioning server at the same time. By default, the automatic update feature is disabled
(see AUTO_UPDATE_RANGE).
- x - the time after midnight that the automatic update occurs.
• AUTO_UPDATE_TIME_RANGE [x] — is the range in hours, from the
AUTO_UPDATE_TIME where an IP Deskphone checks for updates from the server. The
default range is 1 hour.
- x — the range in hours when the IP Deskphone checks for updates from the server.
The range can be from 1 to 6 hours.
• TRANSFER_TYPE [MCS | STANDARD] — is used to configure the IP Deskphone to
activate Avaya conference server-assisted attended transfers, instead of the industry
standard method of attended transfers. The default setting is Standard.
- MCS - the typical attended transfer used by Avaya proxies. MCS uses a conference
server to do the attended transfer.
- STANDARD - the standard method of a transfer. This method does not involve a
conference server.
• REDIRECT_TYPE [MCS | RFC3261] — is a command used to select different protocols
for IP Deskphone redirection. The default setting is MCS.
- MCS - when the IP Deskphone receives either 301 (moved permanently) or 302
(moved temporarily) during registration, it is assumed the IP Deskphone is moved
to a new system (proxy+registrar) and all subsequent messages are sent to the new
address.
- RFC3261 - the IP Deskphone assumes that, if during registration, a 301 (moved
permanently) is received, the message contains a new registrar address. The
IP Deskphone tries to register to the registrar using the existing proxy.
• ENABLE_PRACK [YES | NO]
PRACK is utilized to make some SIP messages reliable and requires that an ACK be sent
with many SIP messages. ENABLE_PRACK is often utilized to verify that early media is
being received. See RFC3262 for details.
