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/TFTP
• 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
Configuration
ip dhcp excluded-address 192.1.201.250 192.1.201.254
ip dhcp pool Phones
network 192.1.201.0 255.255.255.0
option 150 ip 192.1.201.254
• default-router 192.1.201.254
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
