69.7 General SIP Parameters
The general SIP parameters are described in the table below.
Table 69-32: General SIP Parameters
Parameter Description
[MaxSDPSessionVersionId] Defines the maximum number of characters allowed in the SDP body's
"o=" (originator and session identifier) field for the session ID and
session version values. An example of an "o=" line with session ID and
session version values (in bold) is shown below:
o=jdoe 2890844526 2890842807 IN IP4 10.47.16.5
The valid value range is 1,000 to 214,748,3647 (default).
[UseRandomUser] Enables the device to assign a random string value to the user part of
the SIP Contact header for new user Account registrations with the
device. The assigned user part is unique to each Account. An example
of a randomly assigned user part is shown (in bold) below:
Contact: <sip:HRaNEmZnfX6xZl4@pc33.atlanta.com>
When enabled, each Account registers with its unique user part, and
all INVITE messages for this new Account are sent with this unique
user part. These assigned user parts are also used for registration
refreshes and for un-registering these Accounts. The assigned user
parts are used until the parameter is disabled. When enabled again,
new random user parts are assigned to the Accounts.
 [0] = (Default) Disable
 [1] = Enable
To configure Accounts, see Configuring Registration Accounts
on page
395.
[UnregisterOnStartup] 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
