Example for Configuring Voice Services for Small- and Medium-sized Enterprises
Networking Requirements
The PBX configures the external number allocated to an enterprise by the carrier as the automatic switchboard number. An outer-office user dials the external number and then dials an extension number as prompted to connect to an intra-office user. Intra-office users make calls to each other by dialing short numbers. Figure1 shows the voice service network.
This topic assumes that you want to implement the following requirements:
- The country code is 86, and the area code is 571.
- The internal numbers of users A, B, and C are 7000, 7001, and 7100 respectively.
- Users A, B, and C belong to enterprise hw. The DN set is local. The intra-office call prefix is 7. The outgoing call prefix is 9. The incoming and outgoing call rights of all users are all.
- Both the signaling IP address and media IP address are 192.168.1.2.
- The automatic switchboard name is ivr. A number allocated by the PSTN is used as the automatic switchboard number, such as 28980808.
- Post-routing number change scheme 9 is configured to retain calling numbers and delete the first digit of called numbers when PBX users make outgoing calls through the FXO port.
Prerequisites
The IVR configuration has been completed. For details, see IVR. vu-service-name configured for the automatic switchboard is service for the IVR.
Data Plan
The data plan provided in this example is for reference only. Plan data by negotiating with users and the carrier.

Item
Expected Result
Possible Fault Cause
Intra-office call
Calls can be made properly, and the calling number is correctly displayed. For example, user 7000 can dial 7100 to make a call to user 7100, and the calling number displayed to user 7100 is 7000.
The intra-office call prefix is incorrectly configured.
Outgoing call
Calls can be made properly, and the calling number is correctly displayed. For example, user 7000 can make an outgoing call through the AT0 trunk, and the calling number displayed to the called party is 28980808.
- The outgoing call prefix is incorrectly configured.
- The outgoing trunk is incorrectly configured.
Incoming call
Calls can be made properly. For example, an outer-office user can dial 28980808 and then dial 7000 as prompted to connect to user 7000.
