746 Matrix PRASAR UCS System Manual
• enable Closed User Group (CUG) in the Class of Service assigned to the extension users.
You need to make sure the following parameters of the CUG table are configured as mentioned below:
• Index: Maximum 250 different routes (001-250) can be programmed.
• Route Code: Route code could be of maximum sixteen digits. Valid Digits: 0 to 9, #, *, +, . (Dot).
Generally, route code will be a unique number. The route code should not clash with any of the extension
numbers of same System. For example in the figure given above, route code for System-A can be defined
as ‘21’, route code for System-B can be defined as ‘22’ and that for System-C can be defined as ‘23’. This
means that no extension in System-A can start with ‘22’ or ‘23’. Similarly, no extension in System-B can
start with ‘21’ or ‘23’ and no extension in System-C start with ‘21’ and ‘22’.
• OG Trunk Bundle Group: An OG Trunk Bundle Group (OGTBG) is assigned to each route code.
Whenever a call is to be made on that route, a free trunk from the OGTBG is selected and the extension
number is dialed on it. The same logic of rotation On/Off for trunk selection from the OGTBG is used. If
rotation is OFF then always the first trunk in the OGTBG is selected. If it is busy then the next trunk in the
group is selected. This helps to select an alternate route. Whereas if rotation is ON then the trunks in the
OGTBG are selected in round robin fashion.
• Strip Digit Count: This count signifies the number of digits to be stripped off while dialing a number. To
elaborate as per the requirement if extension 2001 of System-B dials 212002 and if SIP Trunk 1 is busy
then the call should reach extension 2002 of System-A through alternate route. In this case the strip digit
count of System-A should be programmed as 2 and that of System-B and System-C should be
programmed as 0. Doing so, when extension 2001 of System-B dials 212002 and if SIP Trunk 1 is busy
then the call is routed through System-C. In this case, System-B dials 212002 on SIP Trunk 3, System-C
receive this code and dials out the same code, that is, 212002 on SIP Trunk 2 without striping of any digit.
