I can access the Internet, but cannot make VoIP calls.
1 Make sure you have the VOICE > Service Configuration > SIP Settings screen
properly configured
2 The VoIP LED should come on. Make sure that your telephone is connected to the VoIP
port (see the Quick Start Guide for information on connecting telephone cables to the
these ports).
3 You can also check the VoIP status in the Status screen.
4 If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you cannot
make a call using speed dial, there may be something wrong with the SIP server. Contact
your VoIP service provider.
Problems With Multiple SIP Accounts
You can set up two SIP accounts on your WiMAX Modem. By default your WiMAX Modem
uses SIP account 1 for outgoing calls, and it uses SIP accounts 1 and 2 for incoming calls.
With this setting, you always use SIP account 1 for your outgoing calls and you cannot
distinguish which SIP account the calls are coming in through. If you want to control the use
of different dialing plans for accounting purposes or other reasons, you need to configure your
phone port in order to control which SIP account you are using when placing or receiving
calls.
