starts with 100 to 199 and ends with 100, 101 or 105. To denote 
any prefix, use the asterisk (*) symbol (default) or to denote calls 
without a calling number, use the $ sign. For a description of

Manipulation Tables'' on page 999. 
The number can include up to 50 digits.

Action 
Destination IP Group 
dst-ip-group-id 
[PREFIX_DestIPGroupName] 
Assigns an IP Group to where you want to route the call. The SIP 
INVITE message is sent to the IP address configured for the 
Proxy Set that is associated with the IP Group. 
Note: 
  If you select an IP Group, you do not need to configure a 
destination IP address. However, if both parameters are 
configured in the table, the INVITE message is sent only to the 
IP Group.  
  If the destination is a User-type IP Group, the device searches 
for a match of the Request-URI in the received INVITE to an 
AOR registration record in the device's database. The INVITE 
is then sent to the IP address of the registered contact. 
  If the AlwaysUseRouteTable parameter is set to 1 (see 
''Configuring IP Groups'' on page 363
), the Request-URI host 
name in the INVITE message is set to the value configured for 
the 'Destination IP Address' parameter (in this table); 
otherwise, if no IP address is defined, it is set to the value of 
the 'SIP Group Name' parameter (configured in the IP Groups
