Feature Prefix

Feature prefixes allow you to modify how the call behaves by adding a prefix to the called number. The system interprets the prefix, then strips it off before routing the call.

To add a new feature prefix

  1. Log in to the VProvider web interface.
  2. Go to Features ยป Feature prefixes.
  3. Click the “New” button.
  4. Enter the following:
    • The prefix to match.
    • The minimum and maximum length of the called number to match. This includes the prefix.
    • Optionally a description.
    • The purpose of the feature prefix. See below for details.
    • If you are logged in as a system owner, whether the feature prefix may be used by all customers on the system.
  5. Click the “Save” button.

The following purposes are defined:

  • Call an external number. This can be used to implement 9 for an outside line.
  • Call a mailbox. This can be used to transfer callers straight to voicemail if you know the person you wish to transfer them to is unavailable.
  • Call a plugin. The plugin can access the remainder of the called number after the prefix using the ${VPROVIDER-SUBNUMBER} variable.
  • Call a SIP domain. Routes the call to a number at the specified SIP domain.
  • Call a telephone line. This can be used to directly call a telephone line if there is a feature code with the same number.
  • Hide the callerid.
  • Join a conference without asking for the conference code. The caller can be asked for a PIN, or can be put directly in the conference as administrator, talker, or listener without asking for a PIN.
  • Page a telephone line.
  • Park the call on a specific parking slot.
  • Record the call. Note that the record group settings, such as percentage of calls to record, still apply. Therefore it’s possible that the call will not actually be recorded.
  • Replace the prefix. The prefix will be replaced by the “Replace with” value. This allows creation of short dials to external number ranges, or replacement of the international access code.
  • Set call forwarding. Dial the prefix followed by a number to set call forwarding to that number for the telephone line you are calling from.
  • Set the call media to voice or fax (if configured).
  • Set the callerid.
  • Spy on the call. Optionally, the spy can talk to the caller. A PIN can be specified to protect this feature.
  • Use a remote access menu. Dial the prefix, followed by the remote access account, followed by *, the PIN followed by * (if the account has a PIN), then the destination.
  • Use a voucher.
