User’s Guide

IVR (Interactive Voice Response) is a feature that allows you to use your 
telephone to interact with the WiMAX Modem. The WiMAX Modem allows you to 
record custom tones for the Caller Ringing Tone and On Hold Tone functions. 
The same recordings apply to both the caller ringing and on hold tones. 

Expiration Time Keep the default value, unless your VoIP service provider tells you to 

change it. Enter the number of seconds the SIP server should provide 
the message waiting service each time the WiMAX Modem subscribes to 
the service. Before this time passes, the WiMAX Modem automatically 
subscribes again.

Fax Option
G.711 Fax 
Passthrough

Select this if the WiMAX Modem should use G.711 to send fax 
messages. The peer devices must also use G.711.

T.38 Fax Relay

Select this if the WiMAX Modem should send fax messages as UDP or 
TCP/IP packets through IP networks. This provides better quality, but it 
may have inter-operability problems. The peer devices must also use 
T.38.
