It is recommended that your ISDN connection has the following characteristics:
- PRI: The size of the DID range that you specify for your PRI depends only on the number of different endpoints or destinations on your local network. For example, if you have 100 endpoints on your network, you would get one DID number for each one, and would need to set up dial plan rules on your IDSN Gateway to map DID numbers to endpoints
