the SIP server (

Figure 91

STUN

Outbound Proxy

Your VoIP service provider may host a SIP outbound proxy server to handle all of the WiMAX

Device’s VoIP traffic. This allows the WiMAX Device to work with any type of NAT router and

eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of the

WiMAX Device to keep it from retranslating the IP address (since this is already handled by the

outbound proxy server).

NAT and SIP

The WiMAX Device must register its public IP address with a SIP register server. If there is a NAT

router between the WiMAX Device and the SIP register server, the WiMAX Device probably has a

private IP address. The WiMAX Device lists its IP address in the SIP message that it sends to the

SIP register server. NAT does not translate this IP address in the SIP message. The SIP register

server gets the WiMAX Device’s IP address from inside the SIP message and maps it to your SIP

identity. If the WiMAX Device has a private IP address listed in the SIP message, the SIP server

cannot map it to your SIP identity.

Use a SIP ALG (Application Layer Gateway), STUN, or outbound proxy to allow the WiMAX Device to

list its public IP address in the SIP messages.

DTMF

Dual-Tone Multi-Frequency (DTMF) telephone call signaling uses pairs of frequencies (one lower

frequency and one higher frequency) to set up calls. It is also known as Touch Tone. Each of the

keys on a DTMF telephone corresponds to a different pair of frequencies.

Supplementary Phone Services Overview

Supplementary services such as call hold, call waiting, call transfer, etc. are generally available from

your VoIP service provider. The WiMAX Device supports the following services:

•

Call Waiting

•

Call Forwarding

•

Caller ID

Note: To take full advantage of the supplementary phone services available though the

WiMAX Device's phone port, you may need to subscribe to the services from your

VoIP service provider.
