Example for Configuring Voice Services for a Small- or Medium-sized Enterprise

Latest reply: Jan 29, 2016 23:12:08 3398 3 0 0

As shown in Figure 2-29, an enterprise has POTS users: User A, User B, and User C. The requirements are as follows:
  • Internal calls of the enterprises are connected through the PBX, and outgoing calls from the enterprises are connected to external users through the AT0 trunk.
  • The carrier allocates the number 56623000 to the enterprise. External users can dial the number 56623000 to query internal extension number. External users can also dial the number 56623000, and then the call is transferred to an internal user.
     Example for Configuring Voice Services for a Small- or Medium-sized Enterprise-1292363-1 NOTE:

    This example uses the voice tone "Please dial the extension number, or dial zero for the operator."

Configuration Roadmap

The configuration roadmap is as follows:

  1. Set the service mode to PBX.

  2. Configure the default country code and area code.

  3. Configure the enterprise, DN set, and RTB file.

  4. Configure prefixes.

  5. Configure PBX users.

  6. Configure a trunk and a trunk group for inter-office calls.

  7. Configure a call route and a post-routing number change plan.

  8. Configure an IVR group.

Data Preparation

To complete the configuration, you need the following data:

  • Country code and region code: 86 and 25

     Example for Configuring Voice Services for a Small- or Medium-sized Enterprise-1292363-3 NOTE:

    The country code and region code in China are used as an example.

  • Extension numbers of User A, User B, and User C: 800, 801, and 802 (the access number of the IVR group is 800)

  • Enterprise that User A, User B, and User C belongs to: hw

  • DN set: local

  • Intra-office and inter-office call prefixes: 8 and 9

  • Call-in and call-out permissions: 3

  • IVR group name and user-defined RBT file name: ivr1 and sss.wav

     Example for Configuring Voice Services for a Small- or Medium-sized Enterprise-1292363-4 NOTE:

    If the user-defined RBT is used, ensure that the RBT file has been made and uploaded/downloaded to the storage media.

  • When the AT0 trunk is used to make inter-office calls on RouterA, configure post-routing number change plan 9. In the plan, the calling number remains unchanged, and one digit is deleted starting from the seventh digit in the called number.
     Example for Configuring Voice Services for a Small- or Medium-sized Enterprise-1292363-5 NOTE:

    For details on how to calculate the start digit to be deleted and the number of digits to be deleted, see 2.15.7 Configuring the Post-routing Number Change Service.

Procedure

  1. Set the service mode to PBX.
     Example for Configuring Voice Services for a Small- or Medium-sized Enterprise-1292363-6 NOTE:

    The PBX functions are controlled by the license. By default, PBX functions are disabled on a newly purchased device. To use the PBX functions, apply for and purchase the license from the Huawei local office.
