Setting Up IP Extensions

The AltiGen IP phone communicates with the system using SIP protocol to establish the signaling channel and media channel (the voice steam, using RTP protocol). With SIP implementation, the system establishes a signaling channel to an IP phone when the IP phone is in use.

Figure 1. Concept of signaling and media channels

The media channel (voice stream) is connected between two IP phones under normal operation. There are some special situations that require you to configure the IP phone to connect its voice stream to the server. Please see “Setting an IP Extension” on page 229 for information.
