After reading through this page you will be fully familiar with all the essential terms concerning Ozeki VoIP SIP SDK activation in a development server and what you will need for creating your own solution using Ozeki VoIP SIP SDK.


Product activation is a license validation procedure required by proprietary computer software programs. After the trial version of a software has expired (after a certain period of days), it is necessary to start the product activation process. This process is tightly connected to the license purchase. See, after the trial period is over you will not be able to use the software anymore without activation. You can get the activation code by purchasing a software license from the vendor company. In most cases you can choose from various licenses, according to your needs.

After you have started the licensing process and have paid for the chosen license, the vendor sends you the unique activation code. You type this code into the window appearing when running the program (after trial period expired), and you are able to use the program again. Moreover, you are able to use the complete version of the program as most trial versions only contain some basic functions of the product.

This page will guide you through the activation process, step by step. After activating Ozeki VoIP SIP SDK on your development server you can start to use the complete version of the program and build your own VoIP solution. Important!: You do not have to purchase a license for every server you use. You can use even a single license on any number of servers.
