Chapter 5: Phonebook Configuration
Example 3: Your company has an IP PBX system with an analog VOIP unit for local calls and direct calls to the office in another city and an MVPGSM that will handle all long distance calls. With this setup, a call control module handles the call routing – when an extension requests an outside line (by dialing a “9” first, for example) the call control module then watches what the first digit after the 9 is. If that first digit is anything other than one of the local area codes, the call is routed through the MVPGSM to take advantage of the cost savings provided by the wireless network. If the first digit is a local call, it is sent through the standard PSTN. The analog VOIP could also be setup to connect with a remote office VOIP as well. In this case then, there would be another access digit (an “8” for example) to have an extension use the analog VOIP and connect to the remote location as if it were a local call.
Analog VOIP and MVPGSM
The Any Number setup entails determining a series of numbers that the VOIP unit will recognize as needing to be routed to the remote VOIP.
Example 4: An analog VOIP and an MVPGSM are connected to the same network. Calls that are local or on the PBX are routed by the analog VOIP, while calls that are dialed out of the local area are sent to the MVPGSM to use the wireless network and save money. In this case, the MVPGSM is the SIP gateway to the wireless network. Incoming calls to the MVPGSM from an external source will receive the auto attendant and from this, external calls can access the extensions attached to the analog VOIP.
Load Balancing
The MVPGSM uses round robin load balancing to ensure that one or more SIMs are not used excessively while others go largely ignored during times of light traffic. When Hunting is enabled, load balancing is done automatically.
Example 5: Your MVPGSM has both channels populated with
Example Inbound Phone Books
The basic purpose of the Inbound Phone Book is to create rules for routing incoming IP calls. Below you will find the Inbound Phone Book settings for the examples that were detailed in the sample Phone Book Configurations above.
Example 1: Local VOIP has
Example 2: Local VOIP has
Example 3: The Inbound Phone Book for this setup will be set to Any Number for all channels, allowing all digits and relying on the call control module to handle the routing.
Example 4: The outbound number on the analog side matches the inbound number on the MVPGSM. The Inbound Phone Book of the analog VOIP will list the phone number of the MVPGSM.
Example 5: Your Inbound phone book will have one entry that has “Hunting” selected for the ‘Channel Number’ selection box. The other fields will be populated per your setup, but the ‘Any Number’ selection is used in this example to allow any call, all other entries here must have ‘Hunting’ enabled as well to use the load balancing feature.
