User's Manual 17. Control Network
Parameter Description
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.
Note: This parameter is overridden by the ‘Contact User’
parameter in the ‘Account’ table (see 'Configuring Account
Table' on page
213 ).
Local Host Name
[IPGroup_ContactName]
Defines the host name (string) that the device uses in the SIP
message's Via and Contact headers. This is typically used to
define an FQDN as the host name. The device uses this string
for Via and Contact headers in outgoing INVITE messages to a
specific IP Group, and the Contact header in SIP 18x and 200
OK responses for incoming INVITE messages from a specific IP
Group. The Inbound IP Routing table can be used to identify the
source IP Group from where the INVITE message was received.
If this parameter is not configured (default), these headers are
populated with the device's dotted-decimal IP address of the
network interface on which the message is sent.
Note: To ensure proper device handling, this parameter should
be a valid FQDN.
Media Realm Name
[IPGroup_MediaRealm]
Assigns a Media Realm to the IP Group. The string value must
be identical (including case-sensitive) to the Media Realm name
defined in the Media Realm table.
Notes:

For this parameter to take effect, a device reset is required.

If the Media Realm is later deleted from the Media Realm
table, then this value becomes invalid.

For configuring Media Realms, see Configuring Media
Realms on page 188.
IP Profile ID
[IPGroup_ProfileId]
Assigns an IP Profile to the IP Group.
The default is 0.
Note: To configure IP Profiles, see 'Configuring IP Profiles' on
page 225 .
Gateway Parameters
Always Use Route Table
[IPGroup_ AlwaysUseRouteTable]
Defines the Request-URI host name in outgoing INVITE
messages.

[0] No (default).

[1] Yes = The device uses the IP address (or domain name)
defined in the Tel to IP Routing (see Configuring the Tel to IP
Routing on page
256 ) as the Request-URI host name in
outgoing INVITE messages, instead of the value configured
in the 'SIP Group Name' field.
SIP Re-Routing Mode
[IPGroup_ SIPReRoutingMode]
Defines the routing mode after a call redirection (i.e., a 3xx SIP
response is received) or transfer (i.e., a SIP REFER request is
received).

[-1 ] Not Configured (Default)

[0] Standard = INVITE messages that are generated as a
result of Transfer or Redirect are sent directly to the URI,
according to the Refer-To header in the REFER message or
