Numbers, also known as DIDs or DDIs, are normal telephone numbers that external callers can use to call into the system from the PSTN (Public Switched Telephone Network).

To add a new number

1. Log in to the Enswitch web interface.
2. If you wish to record calls to this number, make a record group.
3. Go to Features » Numbers.
4. Click the "New" button.
5. Choose which type of number you'd like.
6. Click the "Next" button.
7. Choose a number. The price you will be charged for the number is shown by the numbers.

9. Enter the following:
   • Optionally a description.
   • The owner. This person may edit the number even if they are not an administrator.
   • Whether to include the number in directory.
   • Whether to screen calls. If set to yes, the person answering will be asked if they wish to accept the call.
   • Optionally force the callerid. This should normally be set to "Original".
   • Optionally the caller name. This allows users on a SIP telephone to see which number the call came from. If not set, the caller name supplied by the caller will be used.
   • Whether the caller name setting above replaces the caller name supplied by the caller, prepends to it, or appends to it.
   • Optionally hang up the call after a certain number of minutes.
   • Which record group to use to record calls, if you have any.

   • Whether to display this number in the control panel.
   • The default destination to route calls to this number to.
