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.
