Overview of Voice over IP (VoIP) and Network Protocols

Initialization Process

These steps offer a high-level description of the information exchanged when the telephone initializes and registers. This description assumes that all equipment is properly administered ahead of time. This description can help you understand how the 4600 Series IP Telephones relate to the routers and servers in your network.

Step 1: Telephone to Network

The telephone is appropriately installed and powered. After a short initialization process, the telephone identifies the LAN speed and sends a message out into the network, identifying itself and requesting further information. A router on the network receives this message and relays it to the appropriate DHCP server.

Step 2: DHCP Server to Telephone

The DHCP file server provides information to the telephone, as described in DHCP and File Servers on page 47. Among other data passed to the telephone is the IP Address of the TFTP or HTTP server, which is crucial for the next step.

Step 3: Telephone and File Server

Beginning with Release 2.2, 4600 Series IP Telephones can download script files, application files, and settings files from either a TFTP, HTTP, or HTTPS server. The HTTPS server applies only if the server supports Transport Layer Security (TLS) encryption. If you have a mixture of Release 2.2 and pre-Release 2.2 telephones, you can use either:

●TFTP servers only.

●Both TFTP and HTTP servers, with TFTP running phones with older releases and HTTP for telephones running Release 2.2 and later software.

A telephone that supports HTTP will attempt to access the HTTP server (if administered), and, if successful, will not attempt to access the TFTP server (if administered).

The script files, application files, and settings files discussed in this section are identical for HTTP and TFTP servers. The general downloading process for those files is essentially the same. One exception is that when you use an HTTPS server, a TLS server is contacted first. Therefore, we use the generic term “file server” here to mean both “TFTP server” and “HTTP server.”
