AirStream 4000/4001 WiMAX CPE User Manual

Proxy can be enabled and configured. And if more than one Proxy Addresses are supplied, the CPE will try each

Proxy sequentially if a request to a Proxy times out with no responses. Apply settings if changes are made in the

above section.

After completing all settings, you may uncheck “Enable Register” and apply settings to de-register the FXS port.

Check “Enable Register” and apply settings again to perform another registration. If a registration is successful,

“Port Status” under “User Configurations” should show “Register Success”.

SIP Protocol parameters, such as Hook Flash, Max Forwards and Max Auth can be configured.

For service provider networks, the SIP control protocol is the mainstream protocol selected by the

telecommunication standardization bodies. For example, 3GPP and 3GPP2 have adopted SIP as the foundation

for future communication networks.

The CPE need not be reset if changes are made at application level, e.g. Proxy IP address change. However the

media protocol can be restarted to effect changes.

Different VoIP network equipment vendors may have implemented SIP protocol in different ways. Table below

summarizes the use of configuration values in various SIP messages.
