QuadroE1/T1 Manual-I: Installation Guide Appendix: Configuring SIP NAT Traversal

Appendix: Configuring SIP NAT Traversal

The QuadroE1/T1 initiates and receives SIP calls from the network connected to the WAN

port) To receive SIP calls, the QuadroE1/T1 must be able to receive packets from the SIP

server or any other device that is trying to make an incoming call. If the QuadroE1/T1 is

placed behind a router with NAT, like most basic routers on the market today, the

QuadroE1/T1 will not be able to receive calls. To resolve this issue, either STUN must be

enabled on the QuadroE1/T1 or SIP NAT traversal must be set up in the router and in the

QuadroE1/T1 to properly route the incoming calls.

NAT or Network Address Translation is a common feature used to expand the use of con-

nected PCs and other networked devices without having to use multiple global Internet pub-

lic IP address. Most ISP will assign one public IP address to each customer that is con-

nected to the Internet. The customer can use a router to provide NAT capability and create a

private network of PCs and other devices not visible to the Internet. This method offers secu-

rity and also eliminates the need to assign global Internet public IP addresses to each de-

vice.

Please Note: SIP NAT traversal only works with Internet connections that have static IP ad-

dresses. Verify from your provider this is the case for your Internet connection. Some ISPs

provide dynamic IP addresses that may change from time to time, and are not appropriate

for SIP NAT traversal.

Please Note: If you have more than one router in series between the QuadroE1/T1 and the

Internet, the same port forwarding setup must be configured on each router.

SIP NAT Traversal Setup

• Install the QuadroE1/T1 behind the router. If the QuadroE1/T1 is configured with its fac-

tory default settings, it is already configured for DHCP and will obtain an IP address

automatically from the router. If the DHCP was changed, please run the Basic Configu-

ration Wizard explained on Step 3 to place the QuadroE1/T1 in DHCP mode. Power up

the QuadroE1/T1.

• Connect a PC or laptop to the QuadroE1/T1 LAN port and power it up.

• Verify the QuadroE1/T1 can connect to the Internet by opening a browser window and

browsing to a familiar WEB site. If the QuadroE1/T1 can not reach the Internet, verify the

LAN/WAN LEDs and the cabling. Verify the QuadroE1/T1 is set up for DHCP on the

WAN and that the router has the DHCP server enabled for the devices behind it.

• Find the address of the router and log into the router. Refer to the router user manual on

how to open the router configuration.

Set up port forwarding on the router to forward UDP• ports 5000-5060 to the IP address

assigned to the QuadroE1/T1. You can see the IP address of the QuadroE1/T1 in the

System menu under Status. The IP address will be listed as the WAN IP address. Your

•

router may also indicate the IP address assigned to the QuadroE1/T1.

Find out the public Internet address of the router. To do so, open a browser and go to

www.whatismyip.com. The site will return your public Internet IP address. Record this IP

address.

From the QuadroE1/T1 Management menu go to the SIP Settings menu and check •

NAT station IP, enter the public Internet IP

n on the Epygi SIP

Server after a few minutes. You can verify the settings from the main QuadroE1/T1 Man-

agement menu under Status in the SIP Registration Status section.

Use Manual NAT Traversal for SIP. For

address found on the step above.

• For Mapped Port for SIP enter 5060

• For Min mapped RTP/RTCP port enter 600

• For Max mapped RTP/RTCP port enter 6059

• Click the Save button to save the contents.

The QuadroE1/T1 will activate the settings and register the extensio
