The Cisco Call Manager Express / UC500 connects onto the LAN via one of the RJ45 sockets on the front of the PBX. The local IP address and other network settings are set through the HTML-based programming interface. Advanced configuration, such as is required for CSTA / XML configuration is normally done via the telnet interface.

Go Connect Server Installation Notes

To perform an installation you will need the IP address of the PBX and a username and password configured for XML use. Also you will need to prepare the Cisco appliance through programming. This programming includes:

  • Configuring the XML gateway service
  • Allowing sip-to-sip connections
  • Enabling CTI integration

For more information please see the ‘Configuring CTI CSTA Protocol Suite in Cisco Unified CME’ guide.


Configuring the Cisco CME for CSTA is considered an advanced subject. Please do not attempt to do this without prior training.
