Hi
one of my users is trying to use a product called dialpad
(http://dialpad.com). it allows free calls from pc to telephone in the US.
however, voice does not come through the gnat box. any ideas what to
configure to allow voice through?
heres the faq from the dialpad website.
Our company has a firewall. Can I use Dialpad.com?
Unfortunately,you cannot use Dialpad.com behind firewall. Our server
cannot penetrate firewall and send you multimedia packets. To use
Dialpad.com service behind firewall, try to open UDP ports 51200, 51201,
and TCP port 51210.
In case you want to allow the ports only for Dialpad. Open them for the
4.2.40.XX, 4.2.41.XX, 4.2.48.XX, 4.2.64.XX, and 4.2.74.XX subnet.
I have a private network, how can I use Dialpad??
If you have a private network, even though you can call someone, you
wouldn't be able to hear the remote end. This is because the incoming
voice packets cannot find its way to the PC without a valid (public) IP
address.
In order to use Dialpad on a private network, you have to map the incoming
ports on the server. You have to map the following incoming ports
UDP: 51200, 51201
TCP: 51210
If you need a trigger for them, use TCP: 7175 (outgoing)
There are many software/hardware out there for routing traffic in a private
network. Although each of them has a different way of configuring the ports,
they basically work the same way. Following are the explanation for each
case known so far. If you are using a software/hardware that is not listed in
here, and managed to use Dialpad, please let us know so that we could
add it to the list.
