Speed Dial and Peer-to-Peer Calling
Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers. It
is also required if you want to make peer-to-peer calls.
In peer-to-peer calls, you call another VoIP device directly without going through
a SIP server. In the WiMAX Modem, you must set up a speed dial entry in the
phone book in order to do this. Select Non-Proxy (Use IP or URL) in the Type
column and enter the callee’s IP address or domain name. The WiMAX Modem
sends SIP INVITE requests to the peer VoIP device when you use the speed dial
entry.
You do not need to configure a SIP account in order to make a peer-to-peer VoIP
call.
