3 Provisioning Tutorial This chapter describes the procedures for transferring configuration profiles between the IP Telephony Device and the provisioning server and includes the following sections: • Preparation, page 63 • Basic Resync, page 64 • Secure Resync, page 72 • Profile Formats, page 77 For information about creating configuration profiles, refer to Chapter 2, "Creating Provisioning Scripts." Preparation The examples presented in this chapter require the availability of one or more servers. For the purposes of this tutorial, these can be installed and run on a local PC. To troubleshoot server configuration, it is helpful to install clients for each type of server on a separate server machine. That establishes proper server operation independent of the interaction with Cisco Small Business VoIP devices. The pertinent servers include: syslog (UDP port 514), TFTP (UDP port 69), HTTP (TCP port 80), HTTPS (TCP port 443). For generating configuration profiles, it is useful to install the open source gzip compression utility. For profile encryption and HTTPS operations, you can install the open source OpenSSL software package. In addition, to test dynamic generation of profiles and one-step remote provisioning using HTTPS, a scripting language with CGI scripting support, such as the open source Perl language tools, is recommended. Finally, to verify secure exchanges between provisioning servers and Cisco Small Business voice devices, it is useful to install an Ethernet packet sniffer (such as the freely downloadable Ethereal/Wireshark). For HTTPS transactions, you can use the ssldump utility. Cisco Small Business IP Telephony Devices Provisioning Guide 63

Provisioning Tutorial
This chapter describes the procedures for transferring configuration profiles
between the IP Telephony Device and the provisioning server and includes the
following sections:
•
Preparation, page 63
•
Basic Resync, page 64
•
Secure Resync, page 72
•
Profile Formats, page 77
For information about creating configuration profiles, refer to
Chapter 2, “Creating
Provisioning Scripts.”
Preparation
The examples presented in this chapter require the availability of one or more
servers. For the purposes of this tutorial, these can be installed and run on a local
PC. To troubleshoot server configuration, it is helpful to install clients for each type
of server on a separate server machine. That establishes proper server operation
independent of the interaction with Cisco Small Business VoIP devices.
The pertinent servers include: syslog (UDP port 514), TFTP (UDP port 69), HTTP
(TCP port 80), HTTPS (TCP port 443). For generating configuration profiles, it is
useful to install the open source gzip compression utility. For profile encryption
and HTTPS operations, you can install the open source OpenSSL software
package. In addition, to test dynamic generation of profiles and one-step remote
provisioning using HTTPS, a scripting language with CGI scripting support, such
as the open source Perl language tools, is recommended.
Finally, to verify secure exchanges between provisioning servers and Cisco Small
Business voice devices, it is useful to install an Ethernet packet sniffer (such as the
freely downloadable Ethereal/Wireshark). For HTTPS transactions, you can use
the ssldump utility.
