Overview
When calls comes into the the outside number may contain extra digits or not be complete, for example contain 141 to suppress caller ID, contain ARS (least cost routing) digits or a user could have dialed a number without the local area code. The system can be configured to "clean" the number before it is stored to provide a consistent format for all numbers.
It is necessary to configure the dial plan to match the configuration of the .

Configuration
To configure the dial patterns:
- Access the Site Settings -> Dial Plan configuration section.
- Enter the settings used to "clean" the number in the Call history section.
- DDI Prefix to add: When an incoming call is received on a direct dial number the telephone network provider often only sends the last few digits of the DDI/DID number dialed. For example if the number 01617123456 is dialed the telephone system only receives 123456. In this case 123456 will be logged against the call. To add the DDI prefix you can enter in the preceding digits for the rest of the number dialed, 01617 value for this example.
- Caller ID prefix to add: When dialing a local outside number the system will only receive the number from OAI without the local area code. Entering this will insert this code as a prefix to any dialed numbers not containing the area code. For example if your local area code is 0161 then you would enter this. If the number 1234567 is called the system would convert this to 01611234567.
- Caller ID prefixes to remove:When outbound calls are made, unwanted prefix digits can be removed by adding the prefixes into this section. Multiple entries can be entered by separating them with a comma. For example if the was configured with 8 as the Outgoing line digit and users regularly dial 141 to suppress CLI, enter 8, 8141.
