This document provides a sample configuration for ... (this introduction should provide a description of the subject matter and any contextual information describing a real-world scenario in which this information might be used.

The information in this document is based on the Cisco Call Manager Express Version 3.x and 4.x


Call Manager Express, CME Basics

Registration Process




       Phone sends DHCP request


       DHCP server sends IP Address, TFTP Server address, and default-router address


       Phone downloads “SEP<mac-address>.cnf” file from the TFTP server


       “SEP<mac-address>.cnf” file contains the address of call-manager/CME router to which it should register.


       Phone registers with CME using skinny protocol (SCCP) via TCP on port 2000






       DHCP can be local or remote


       Can be an open pool or on a per phone basis


       DHCP server should be configured to send default-router and TFTP server IP address in addition to the Phone IP address





        ip dhcp excluded-address


ip dhcp pool Phones


     option 150 ip



Connecting Phones


       Put phone load files in flash

       Add tftp-server commands for phone loads

       Enter “create cnf-files” under telephony-services : This builds the XML Configuration files needed (stored in ram file system instead of flash)

       One shared default XML configuration file is created per type of phone (e.g. 7960, 7910)


       Individual phone XML configuration file requests are directed to the appropriate default using filename aliases

       Show telephony-service tftp-bindings displays the alias to default file relationships
