Overview:

ZEUS positions as a Wi-Fi SIP Phone. It is intelligent communication device, adds Voice-over-IP communications with wireless installations, allowing simultaneous voice and data support on the same wireless backbone. It makes standard voice telephone calls when in range of and configured for an appropriate 802.11g access point. The Wi-Fi Phone has the same form factor, buttons and screens as a cell phone. Operation is almost identical to a cell phone as well. The Major difference is in coverage. The Wi-Fi Phone works only where 802.11g coverage is available.

Prerequisites

You will need to arrange with a VoIP service provider for VoIP (voice over internet protocol) service.

Your VoIP service provider must provide you with the following information:

Your phone number, consisting of decimal digits.

SIP server address, in dotted decimal notation only.

SIP server port if different than the industry standard port 5060.

SIP proxy address, (frequently the same as SIP server address).

SIP proxy port if different than the industry standard port 5060.

Proxy user name and password (if used).

STUN server address, if required for NAT traversal.

STUN server port, if different than the industry standard port 3478.

Whether g711 or g729 codecs are supported. Usually, g711 codec is always supported.

You will need to arrange for 802.11g network connectivity.

For use of an open network as a guest (e.g. commonly available at coffee shops, motels, etc.) you will need to know only the SSID (name) of the access point(s), although even this information is frequently obvious from discovery (see Menu / Net Settings). NOTE that the handset does NOT support networks that require logging in or paying via a web page, because the handset does not display web pages.

You may possibly need to give your network administrator the following information:

The MAC address of your Wi-Fi SIP Phone.

This consists of 6 pairs of letters and/or digits, with the pairs separated by colons. It can be found from the status menu item.
