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.
• BLIND_TRANSFER_EARLY_RELEASE [YES | NO] — This parameter determines whether
phone allows releasing while it is in transfer state.
- YES — enables the possibility to switch to idlestate after "release" keypress during transfer
state until transfer is finished or failed.
- NO — it is not possible to exit transferring state until transfer is finished or failed (default).
• 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.
Note:
ENABLE_PRACK must be configured as NO when connected to the MCS 5100 Release
3.5 system.
Note:
ENABLE_PRACK is provisioned after user logoff.
- NO - disables PRACK and is the default value.
- YES- enables PRACK.
