How to setup Ozeki VoIP SIP SDK with Cisco Unified Communications Manager 8

Ozeki VoIP SIP SDK offers the ability to use VoIP services in your own application. You can use it to create an autodialer, a custom softphone or a webphone, for example. To get started, you need to connect it to a PBX first. In this guide you can read about how you can connect Ozeki VoIP SIP SDK to the one of the most powerful PBX application, Cisco Unified Communications Manager.

Cisco Systems is one of the industry-leading solution providers nowadays. They provide networking and voice solutions and services. Their former PBX application, named Cisco Call Manager evolved and extended into an industry standard communication server. Cisco Call Manager became Cisco Unified Communications Manager, and its main innovation is the ability to integrate video support in voice communication.

Ozeki VoIP SIP SDK utilizes the advantages of VoIP technology, which allows you to make phone calls over your existing network infrastructure. You can connect Ozeki VoIP SIP SDK to Cisco Unified Communications Manager to build your own application with voice support.

In this guide you can learn about how to connect Ozeki VoIP SIP SDK to your Cisco Unified Communications Manager and how to start your calls and build your own application.


If you follow the steps of the configuration guide below, you will have a system which is connected to Cisco Unified Communications Manager. The system will work as follows:

Before you start, it is assumed that you have already set up your Communications Manager in your environment. First, you need to set up a Phone Security Profile. Then you need to create a Phone and a Directory Number for the phone. After these, you need to create an End User and assign the Phone for this user. Then Ozeki VoIP SIP SDK can use this created user to connect to Cisco Unified Communications Manager and to make phone calls. Figure 1 demonstrates the process.

After the setup, your system will work as follows:

  1. Login to Cisco Unified Communications Manager and setup the user and the device
  2. Ozeki VoIP SIP SDK will register to Cisco Unified Communications Manager using the created user
  3. You can start to call your contacts via Cisco Unified Communications Manager.

Configuration steps

Step 1.) Configure Cisco Unified Communications Manager

In order to begin the configuration of Cisco Unified Communications Manager, you need to log into its web interface. In this example, it has the following IP address:

This case, the URL of its web interface will be:

Open a web browser, navigate to its web interface, and login as Administrator (Figure 2).

Once logged in, you need to enable Digest Authentication for SIP devices. To do so, I will setup a new Phone Security Profile. Click on the System menu, open the Security sub-menu and select Phone Security Profile (Figure 3).
