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.
