Through support of up to six external Expansion Modules, IP406 can be enhanced to support a mixture of
analog, digital or IP phones, to maximum of 190 phones in any combination.

If additional analog trunks are required, these can be aggregated in groups of 16 on each analog expansion
module

 

A Data Channel is used for Remote Access (RAS), Internet Access, and Voicemail sessions. A data channel is
an internal signaling resource used whenever a call is made from the IP network to an exchange line (Central
Office). For example, four people surfing the Internet will use a single data channel since they all share the
same line to the ISP. Two people remotely accessing the Office LAN from home will use two data channels
since they have dialed in on separate lines. IP extensions do not use data channels. Data channels are used for
voicemail connections with a maximum of 20 available for VoiceMail Pro on an IP406 V2.

 

You can add additional hardware to the IP406 system to add one modem card (2 or 12 V.90 modems) and 1
Voice Compression Module (VCM). The VCM supports from 4 to 30 simultaneous Voice over IP sessions and is
used for either providing networking between sites over a Wide Area Network or supporting IP Telephones and
Soft phones.
