I have been using the new MagicJack Plus with my Time Capsule 2TB with no problems for 6 months. Then it stopped working.

Did you happen to upgrade the firmware? Just then.. as Apple just pushed out 7.6.4.. and that will probably kill it.

It will work via the Mac because Mac's open ports with NAT-PMP .. a system only Macs have and is apple's replacement to the rest of the world using upnp.

To figure out the IP of the MagicJack and its MAC address is tricky.. Apple does show that info for wireless but not for wired connections.

You might find that info will show up in the log of the TC. You will need to use v5 utility to get it.

But there is a fairly if not exactly straight forward way. (Every device btw should have its MAC address printed on it).

If the TC is at standard IP, ie 10.0.1.1 it will be very uniform in handing out addresses starting from 2 and up.

So lets get rid of everything else.. shut down the network.. everything off. .and start up in order..

Modem ..

TC..

Computer..

MagicJack.

Nothing else. Leave 2min between each start up.

You can pretty well guarantee the computer is 10.0.1.2 and the MagicJack is 10.0.1.3

Ping the IP of the MagicJack in the computer in a terminal..

ping 10.0.1.3

Use control C to stop the ping after a few responses.

Now type the command arp -a

(On Lion or Mountain Lion it should be the same.. but I am not sure).

When I type that command all known IP addresses and their MAC address are shown.

So I plugged my VOIP ATA into the TC.. I know its address.. from elsewhere. I ping it and there it is in the arp table.

arp -a

You have to ping it first otherwise it will not show up.

c470-ip.local (192.168.2.100) at 0:1:e3:77:80:5b on en1 ifscope [ethernet]

Then you have the name of the device.. c470-ip.local

Its IP address. 192.168.2.100

and the MAC address 0:1:e3:77:80:5b to fix in the TC for port forwarding.

If you need btw.. 0 is 00 and 1 is 01 just if the full thing is required.

Bit complicated sorry.. but nothing else comes to mind.

Unless you have a modem router.. if you have a modem router.. put it in router mode and bridge the TC.. then your problems will go away.

Normal voip will use TCP 5060.. but this is probably not SIP..

The easiest way is to get a standard router and use the TC in bridge mode for backups and wireless.

The last one is 0f since it is effectively f.. the arp doesn't bother to record it.

A quick google and you will find the port required are far more extensive.

http://www.moushigo.com/index.php/2009/01/29/magicjack-installation-firewall-set up-and-port-settings/

TCP Ports List: 80 (HTTP), 443 (HTTPS)

UDP Ports List: 5060, 5070, 10000-65535

This is the list that somebody experimented and found was required.. of course it is not really the whole range of 10000-65535.. it is just so they have the actual RTP speech ports able to use anything above 10000.
This is why it is better to stick to genuine SIP products and not special bits and pieces that have no recognised standards at all.

Let me suggest instead of port forwarding you simply put the MagicJack in the TC DMZ.
Yes, it does have a DMZ.. go to the Network page and check the default server and put in the IP of the MagicJack.

In apple terms it is called the Default host
