Many Modems require port forwarding if you are using an ATA or softphone behind a modem with a NAT firewall. Most modems come with a hardware firewall which is there to protect you against attacks from Hackers, Trojans and Worms. This firewall needs to be told to allow traffic through on the ports that are used to send VoIP data.
Note: modems supplied by gotalk do not require port forwarding
Each ATA (or computer if you are using a softphone) will have its own IP address, this is to identify the device or computer on the Local Network, when you are trying to make VoIP calls and your modems hardware firewall is blocking the call data from going to the outside world, you must go into your modem and tell it to allow VoIP traffic in and out and tell it where the traffic is coming from and going to. To achieve this you must give the modem all the information that it requires, if you do not supply the modem with all of the information the port forward will fail and your firewall will still be blocking your VoIP traffic.
VoIP traffic travels on ports 5060 & 8000 on UDP & TCP (Network Protocols).
The ports that needs to be forwarded are:
Range 5060 to 5070
Select UDP and TCP
Input the IP address of ATA or computer if using a softphone
Once you have completed the port forward for ports 5060 you must complete a second port forward for ports 8000 - 8011, this is done exactly the same way.
The ports that needs to be forwarded are:
Range 8000 - 8011
Select UDP and TCP
Input the IP address of the ATA or computer if using a softphone
Below is a list of modems and links to instructions on how to port forward each device. The port forwards shown are for the XLite softphone, follow these instructions even if you are using an ATA or a different softphone, if you are asked to name the service that you are forwarding simply change the name from XLite to the name of your ATA or softphone.
Important to Note: gotalk technical support does not step customers through port forwarding due to the fact that performing advanced setting configuration inside your modem can damage your device if not performed correctly, for this reason it is best to consult your manufacturer for advanced configuration such as port forwarding.
