Brekeke SIP Server Upper/Thru Registration Features

Upper and Thru Registration are unique features of Brekeke SIP Server. These functions allow you to easily configure your Brekeke SIP Server to work with other SIP servers.

We assume in this situation that SIP server A is an existing SIP server, either at your office or owned by a VoIP provider. Clients a, b, and c are existing VoIP phones, registered to server A.

You can register IP phones (d, e, f) on a different network to server A through your Brekeke SIP Server instead of registering them to server A directly. (See the image below)

Upper Registration

Clients d, e, and f register themselves to Brekeke SIP server B. Server B registers those clients to SIP server A. Server A will handle the REGISTER requests as if they came directly from the clients, rather than from server B.Using this Upper Registration function, servers A and B can work together without changing server A's configuration.

Thru Registration

In SIP client d, e, and f's settings, server B's IP address should be set as Register Server and Outbound Proxy server. Server A's IP address or FQDN should be included in each client's SIP URI.

Clients d, e, and f register themselves to server B with these settings, and Brekeke SIP Server routes the REGISTER requests to server A. Because Brekeke SIP Server will also register them to itself, clients a, b, and c can call clients d, e, and f. You can specify only one SIP server with Upper Registration, whereas with Thru Registration, you can choose a different SIP Server for each client.

Notes for Using Brekeke SIP Server's Upper/Thru Registration

Upper and Thru Registration are functions for Register process. In other words, these functions are for clients d, e, and f to receive calls from other SIP Servers. You would need to change your Dial Plan in Brekeke SIP server B to allow clients d, e, and f to call clients a, b, and c through servers A and B

Suppose you open a new office and use an Brekeke SIP Server (B) and three IP phones (d,e,f).

* We recommend that you use Brekeke PBX in the case that you want to create an intercom system using many SIP clients in your office and register some of your phones to other SIP Servers as described above. Brekeke PBX utilizes Brekeke SIP Server's Thru registration function and works together with other SIP Servers. The configuration is easier using only Brekeke SIP Server; furthermore, you can use many other PBX functions such as auto attendant and call forwarding.
