Chapter 4 Cisco Call Back
Configuring Cisco Call Back Feature
Cisco recommends that you use the default service parameters settings unless otherwise instructed by the Cisco Technical Assistance Center. Cisco Extended Functions includes the following parameters for Cisco Call Back:
•CTI Connecting Port—Default specifies port 2748. If this port number changes, restart the Cisco Extended Functions service.
•Provider Open Call Time Out—Default specifies 30000. This parameter specifies the wait time of the Cisco Extended Functions service after provider open requests are issued to Cisco CTIManager. If this wait time changes, restart the Cisco Extended Functions service.
•HeartBeat Interval Time Out—Default specifies 30. Cisco Extended Functions and Cisco CTIManager exchange heartbeats to maintain the connection. If this interval time out changes, restart the Cisco Extended Functions service.
•Connection Retry Time Out—Default specifies 60000. Cisco Extended Functions retries to reconnect to Cisco CTIManager if a connection drops. If this retry timeout changes, restart the Cisco Extended Functions service.
•Synchronous Request Time Out—Default specifies 20000. This parameter specifies the wait time of the Cisco Extended Functions service after a synchronous request is issued. If this requested timeout changes, restart the Cisco Extended Functions service.
•Audio File Name—Default specifies CallBack.raw. The Call Back.raw file, located in the directory C:\Program Files\Cisco\TFTPPath gets uploaded to the Cisco IP Phone by Cisco TFTP during the restart cycle. This file contains the twinkle sound that the Cisco IP Phone plays during Call Back notification. The Audio format specifies 64 kbps audio mu-law. If this file name changes, restart the Cisco Extended Functions service.
•CBB Change Notification TCP Port—Default specifies 2552. This parameter specifies the port number of the Cisco Extended Functions database change notification receiving TCP port. The Cisco Database Layer Monitor sends database change notifications. If this port number changes, restart the Cisco Extended Functions service.
