Preventing Toll Bypass

Last Updated : Jul 13, 2021 |

Use this procedure to prevent toll bypass in Enterprise Branch and Small Community Network (SCN) deployments. Toll bypass is prevented by only allowing PSTN calls where the originating location and terminating location are the same.

The location of non-IP lines is the same as the system location. If an IP address is not resolved to any location, then that device is assumed to be in the system location. The location of public IP lines must be configured to same as PSTN termination location.

The Location field for extensions with simultaneous login must be automatic and the location tab must be properly configured for the IP range.

Enterprise Branch deploymentsAll the distributed users must be in the same location as system location. Users registering from a location different from the system location are not supported.

Procedure

  1. In the navigation pane on the left, select System.
  2. In the details pane, click the Telephony tab.
  3. Under Telephony, click the Telephony tab.
  4. On the Telephony tab:
    1. Click the check box to turn Restrict Network Interconnect on.
    2. Click the check box to turn Include location specific information on.

      Setting the two configuration setting on the Telephony tab adds a Network Type field to the configuration settings for each trunk.

  5. For Enterprise Branch deployments, open the SM Line | Session Manager tab. For SCN deployments, open the IP Office Line | Line tab.
  6. If the line is a PSTN trunk (includes SIP), set Network Type to Public. If the line is an enterprise trunk, set the Network Type to Private.
  7. If the Network Type is Private, the Include location specific information field is available.

    If the line is connected to an Avaya Aura® system release 7.0 or higher, or an IP Office release 9.1 or higher, set Include location specific information to On.
