Example for Configuring PBX Sharing for Different Enterprises
Networking Requirements
Users A and B belong to enterprise 1. Users C and D belong to enterprise 2. Enterprises 1 and 2 are in the same industrial campus. By configuring different enterprises on the device, you can logically isolate multiple enterprises' voice services, implementing PBX sharing. Enterprises 1 and 2 can use virtual PBXs to implement voice services for intra-office users and use a unified egress to implement voice services between intra-office and outer-office users. This reduces enterprise costs as well as the carrier's access points. Figure 2-84 shows the PBX sharing network.
This topic assumes that you want to implement the following requirements:
- The external number allocated by the carrier to enterprise 1 is 56623000. When an outer-office user dials 56623000, user B's phone rings. If the outer-office user wants to make a call to an intra-office user other than user B, the call can be transferred by user B to the target user.
- The external number allocated by the carrier to enterprise 2 is 56623001. When an outer-office user dials 56623001, user C's phone rings. If the outer-office user wants to make a call to an intra-office user other than user C, the call can be transferred by user C to the target user.
- The country code is 86, and the area code is 571.
- The internal numbers of users A, B, C, and D are 7100, 7000, 6000, and 6100 respectively.
- Both the signaling IP address and media IP address are 192.168.1.2.
- Users A and B belong to enterprise hw. The DN set is local. The intra-office call prefix is 7. The outgoing call prefix is 8. Users C and D belong to enterprise hw1. The DN set is local1. The intra-office call prefix is 6. The outgoing call prefix is 9.
- A SIP AT0 trunk is used to route outgoing calls. The IP address of the IMS is 192.168.10.10, and the port number is 5060.
- Post-routing number change scheme 8 is configured to retain calling numbers and delete the first digit of called numbers when users of enterprise 1 make outgoing calls through the SIP AT0 trunk. Post-routing number change scheme 9 is configured to retain calling numbers and delete the first digit of called numbers when users of enterprise 2 make outgoing calls through the SIP AT0 trunk.
Configuration Roadmap
- Set the service mode of the router to PBX, and set public parameters. Configure enterprises 1 and 2, and connect the enterprises to the router.
- Configure the users, call prefixes, trunk group, call route, and post-routing number change for enterprise 1 so that intra-office users of enterprise 1 can make intra-office and outgoing calls.
- Configure the users, call prefixes, trunk group, call route, and post-routing number change for enterprise 2 so that intra-office users of enterprise 2 can make intra-office and outgoing calls.

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 SIP AT0 trunk, and the calling number displayed to the called party is 56623000.
- 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 56623000 and be transferred to the target user through user 7000.
