User's Manual 17. Control Network
Parameter Description
To configure Media Realms, see Configuring Media Realms on page 337.
Note:
 For the parameter to take effect, a device reset is required.
 If you delete a Media Realm from the Media Realms table that is
assigned to the IP Group, the parameter value reverts to None.
Contact User
contact-user
[IPGroup_ContactUser]
Defines the user part of the From, To, and Contact headers of SIP
REGISTER messages, and the user part of the Contact header of INVITE
messages received from this IP Group and forwarded by the device to
another IP Group.
By default, no value is defined.
Note:
 The parameter is applicable only to Server-type IP Groups.
 The parameter is overridden by the ‘Contact User’ parameter in the
Accounts table (see ''Configuring Registration Accounts'' on page 395).
SIP Group Name
sip-group-name
[IPGroup_SIPGroupNa
me]
Defines the SIP Request-URI host name in INVITE and REGISTER
messages sent to the IP Group, or the host name in the From header of
INVITE messages received from the IP Group. In other words, it replaces
the original host name.
The valid value is a string of up to 100 characters. By default, no value is
defined.
Note:
 If the parameter is not configured, the value of the global parameter,
ProxyName is used instead (see ''Configuring Proxy and Registration
Parameters'' on page 402).
 The parameter overrides inbound message manipulation rules that
manipulate the host name in Request-URI, To, and/or From SIP
headers. If you configure the parameter and you want to manipulate the
host name in any of these SIP headers, you must apply your
manipulation rule (Manipulation Set ID) to the IP Group as an Outbound
Message Manipulation Set (see the IPGroup_OutboundManSet
parameter), when the IP Group is the destination of the call. If you apply
the Manipulation Set as an Inbound Message Manipulation Set (see the
IPGroup_InboundManSet parameter), when the IP Group is the source
of the call, the manipulation rule is overridden by the SIP Group Name
parameter.
 If the IP Group is of User type, the parameter is used internally as a
host name in the Request-URI for Tel-to-IP initiated calls. For example,
if an incoming call from the device's trunk is routed to a User-type IP
Group, the device first creates the Request-URI
(<destination_number>@<SIP Group Name>), and then it searches the
registration database for a match.

utingServer]
