Cisco Call Manager Express is a VoIP solution developed by Cisco Systems. Cisco Call Manager Express supports the SIP protocol therefore you can use any kind of SIP desktop phone or softphone with it. After you have connected Ozeki Phone System XE to Cisco Call Manager Express, you can build your own application with voice and video support - it may be a standard softphone, an IVR system or a call center application.
By following the configuration steps of this guide described below, you will have a telephone system managed by Cisco Call Manager Express, with at least one extension, and Ozeki Phone System XE softphone connected. After connecting various SIP endpoints to Cisco Call Manager Express, you can easily build various VoIP system infrastructures (Figure 1).

Before you start to configure this solution it is assumed that you have already installed your Cisco Call Manager Express, and downloaded Ozeki Phone System XE installer from the download page.
Connect your 3rd party PBX with Ozeki Phone System XE. The computer where you install PBX will be a virtual machine or a computer. Start with a simple installation to co-operate with Ozeki Phone System XE. Follow the installation guide at Cisco CM Express wizard. Use the disk which you downloaded for 3rd party PBX. After you installed the software, configure the network:In the command line interface use the "enable" command, which enables privileged EXEC mode. Then enter the global configuration mode with "configure terminal". Enter DHCP pool configuration mode with the selected name for the DHCP server address pool with "ip dhcp pool [name]". #router>configure terminal #router>ip dhcp pool [name] Finally you should specify the IP address of the DHCP address pool with "network [IP address] [netmask]". Specify the router that the IP phones will use to send or receive IP traffic that is external to their local subnet If you finished you should add the "default-router [ip-address]". Use the simple "end" command to finish your configuration.
After that you can start to configure the SIP account for Ozeki Phone System XE connection.
The first step you need to do is to configure your Cisco router running Cisco Call Manager Express on your network properly. You can connect your Cisco router via Console port (with a DB9 to RJ45 cable) or you can access the same console by telnetting into the router's IP address (Figure 2). After you have logged in you can start configuring the router, if you have sufficient privileges.
Type ena and config t to enter terminal configuration mode (Figure 2).

At first, you need to configure the voice service (Figure 3). Type in the following:
Figure 3 - Configuring voice service
After you have enabled the SIP server, you need to enter the global configuration for SIP (Figure 4). The most important values for the configuration are the IP address of the service and the maximum number of registrations on your system. The service IP address must be your router's IP address. The standard port number for the SIP service is 5060.
Figure 4 - Global SIP configuration
After configuring global SIP settings, you can start adding usable SIP accounts to your Cisco Call Manager Express (Figure 5). The configuration steps are the following:
Figure 5 - Configuring SIP Accounts
After setting these values you can register a SIP endpoint with the above name and password (test/test). The number of this SIP endpoint will be 2000, and it will use the G711 codec. By following the pattern above you can add as many SIP accounts you want.
If you have set up everything properly, you can start registering your SIP endpoints to Cisco Call Manager Express by using the account data you added to it. Figure 6 shows the method of registering the Ozeki Phone System XE to Cisco Call Manager Express, with using the the above added account.
It is assumed that you have already downloaded Ozeki Phone System XE and installed it into you computer.
You will need to login to the Ozeki Phone System XE and install a VoIP provider. At the VoIP provider installation section you can set General, Network and Call options and you can select the audio and the video codecs of the calls.
You can reach the configuration of the VoIP service provider on the How to connect to VoIP service providers page.
