Create the Device Configuration file on the provisioning server 37
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 whereby an IP Phone 1120E checks for updates
from the server. The default range is 1 hour.
— x - the range in hours when the IP Phone 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
Phone 1120E to activate Nortel conference server-assisted attended
transfers, instead of the industry standard method of attended transfers.
The default setting is MCS.
— MCS - the typical attended transfer used by Nortel 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 set redirection. The default setting is MCS.
— MCS - when the IP Phone 1120E receives either 301 (moved
permanently) or 302 (moved temporarily) during registration, it is
assumed the IP Phone 1120E is moved to a new MCS 5100 system
(proxy+registrar) and all subsequent messages are sent to the new
address.
— RFC3261 - the IP Phone 1120E assumes that, if during registration,
a 301 (moved permanently) is received, the message contains a
new registrar address. The IP Phone 1120E 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 RFC 3262 for details.
Note 1: ENABLE_PRACK must be set to NO when connected to
the MCS 5100 Release 3.5 system.
Note 2: ENABLE_PRACK is provisioned after user logout.
— NO - disables PRACK and is the default value.
— YES - enables PRACK.
