If you cannot connect to a wireless LAN, check
that you entered the AP’s settings correctly. The
V660 and the AP must use exactly the same
security settings. Turn the V660 off and on.
Check that the AP is on. If the problem persists,
you may be out of the AP’s coverage area.
7 Making Internet Phonecalls
VoIP (Voice over IP) allows you to make phonecalls over the
Internet. SIP is the protocol the V660 uses to make VoIP
calls. Before you can use the V660 to make VoIP calls, you
need:
• An active account with VoIP service provider that uses SIP.
• A wireless connection between the V660 and an Access
Point (AP). See section 6 for more information.
Do the following to set up your VoIP account on the V660.
