User’s Guide

The following section contains additional technical information about the WiMAX 
Modem features described in this chapter.

The following figure displays the basic steps in the setup and tear down of a SIP 
call. A calls B. 

A sends a SIP INVITE request to B. This message is an invitation for B to 
participate in a SIP telephone call. 

B sends a response indicating that the telephone is ringing.

B sends an OK response after the call is answered. 

A then sends an ACK message to acknowledge that B has answered the call. 

Now A and B exchange voice media (talk). 

Voice VLAN ID

Select this if the WiMAX Modem has to be a member of a VLAN to 
communicate with the SIP server. Ask your network administrator, if 
you are not sure. Enter the VLAN ID provided by your network 
administrator in the field on the right. Your LAN and gateway must be 
configured to use VLAN tags.

Otherwise, clear this field.
