The rules you need to create are dependent on your needs. If you are configuring your system for a business,
for example, you'll probably want to set up rules for business hours, off hours, weekend hours, etc. In any
case, you should also create a calling rule which utilizes the time interval and uses a catch all pattern to route
any calls that don't fit the other rules you've created. This will insure that you don't miss any calls.
Once you have completed the definition of each incoming calling rule, click Update. Click Apply Changes in
the upper right corner of the page to make your changes immediately available. Each rule you create will be
listed on the Incoming Calling Rules page, organized by trunk. From the main page you can either Edit or
Delete the rule.
CSG SIP Communications Gateway Operation/Reference Guide
The Pattern field gives you the ability to use basic pattern
matching to differentiate calls and route them accordingly. For
instance, if a number begins with _9256, and is followed by 7 or
more digits, that would define a call within the state of Alabama. If
a call began with _9 followed by 7 digits, it would be a local call
that probably doesn't require a long distance charge. Instead of
adding a rule for every extension or phone number you call,
specify the pattern in this rule similar to the example. All patterns
begin with the underscore "_" character. There are special
characters which can be used in patterns:
• X - Any digit from 0-9
• Z - Any digit from 1-9
• N - Any digit from 2-9
• [1,2,3,6-9] - Any digit within the brackets, in this instance 1, 2, 3,
6, 7, 8, 9.
• . - The period is the wildcard which will match anything
remaining. For example, _9011. matches anything starting with
9011.
• ! - The exclamation point is a wildcard which causes the
matching process to complete as soon as it can determine that
no other matches are possible.
Note: If you have selected an analog trunk, this field will be
grayed and populate with an s. This is not a pattern, but an
indication that the analog phone should proceed to the
destination.
Select the Destination for the incoming call. You can choose to
send the call to to either a voice menu, a specific extension,
voicemail box, ring group, the operator, or even hang up the call.
• The Local Extension by DID destination setting allows you to
route the incoming call to a local extension based on the DID
(Direct Inward Dialing) number that is sent to you by your
telecommunications provider. Upon selecting Local Extension
by DID, you will notice the Local Extension by DID Pattern
option appear. This option gives you the ability to remove a
specified number of digits from the front of the DID number
string before routing the call to a local extension.
Note: The Local Extension by DID destination setting is not
applicable for analog trunks.
