Parameter Description
Message Manipulation'' on page 401.
Message Manipulation User-
Defined String 2
msg-man-user-defined-
string2
[IPGroup_MsgManUserDef2
]
Defines a value for the SIP user part that can be used in Message
Manipulation rules configured in the Message Manipulations table. The
Message Manipulation rule obtains this value from the IP Group, by
using the following syntax: param.ipg.<src|dst>.user-defined.<1>.
The valid value is a string of up to 30 characters. By default, no value
is defined.
To configure Message Manipulation rules, see ''Configuring SIP
Message Manipulation'' on page 401.
SBC Registration and Authentication
Max. Number of Registered
Users
max-num-of-reg-users
[IPGroup_MaxNumOfRegUs
ers]
Defines the maximum number of users in this IP Group that can
register with the device.
The default is -1, meaning that no limitation exists for registered users.
Note: The parameter is applicable only to User-type IP Groups.
Registration Mode
registration-mode
[IPGroup_RegistrationMode]
Defines the registration mode for the IP Group:
 [0] User Initiates Registration (default)
 [1] SBC Initiates Registration = Used when the device serves as a
client (e.g., with an IP PBX). This functions only with the User Info
file.
 [2] Registrations not Needed = The device adds users to its
database in active state.
User Stickiness
sbc-user-stickiness
[IPGroup_SBCUserStickines
s]
Enables user "stickiness" (binding) to a specific registrar server. The
registrar server is one of the IP addresses of the Proxy Set associated
with this Server-type IP Group. This feature applies to users belonging
to a User-type IP Group that are routed to this destination Server-type
IP Group.
 [0] Disable = After a successful initial registration of the user to a
registrar, whenever the device receives a SIP request or
registration refresh from the user, the device sends the request to
whichever registrar (IP address of the Proxy Set) is currently active.
In the case of proxy load-balancing, there is no certainty to which
IP address the request is routed.
 [1] Enable = The device always routes SIP requests (INVITEs,
SUBSCRIBEs and REGISTER refreshes) received from the user to
the same registrar server to which the last successful REGISTER
request for that user was routed. In other words, once initial
registration of the user to one of the IP addresses of the Proxy Set
associated with this destination Server-type IP Group is successful
(i.e., 200 OK), binding occurs to this specific address (registrar)
and all future SIP requests from the user are routed (based on
matched routing rule) only to this specific registrar.
Note:
 The parameter is applicable only to Server-type IP Groups.
