WLAN Operation – Placing a Call via a SIP Proxy Server

The 3Com 3108 Wireless Telephone is a Session Initiation Protocol (SIP)-based wireless Voice over Internet Protocol (VoIP) telephone. SIP is an internationally recognized standard (IETF RFC 3261) for implementing VoIP. You can make and receive VoIP calls as long as your Wireless Telephone is registered with a SIP proxy server and you are operating it within range of an IEEE 802.11b/g enabled wireless network (WLAN). The SIP proxy server can belong to a wireless Internet Telephony Service Provider (ITSP) or corporate VoIP PBX system, such as the 3Com NBX® System.

When using your 3108 Wireless telephone to make and receive VoIP telephone calls, you do not need to know if the recipient’s connection type is an IP, cellular, or land line based service. Your Wireless phone can call any land line or mobile telephone that a traditional PSTN telephone can connect to as well as the IP telephone network. Calls received from VoIP telephones work exactly as you would expect from the traditional telephone service.

The initial handset parameters and network service must be configured before you can use your Wireless Phone to make or receive any calls. For details, see Chapter 4: Initial Handset Configuration.
