Is SIP/VoIP easy ? depends…. most of the time with the common “Betamax providers” it is,
You should have not much problems, due to standard port addresses, etc… but when you do run into trouble, do you know where to look ? Should you search forever ? No, big chance your router is out of date, and your ATA isn’t the problem, and you then ask yourself, what should I set and where ? Upgrading your (modem)router is a good idea, big chance the new one has allready the “NAT things” set good at its default values, but if you have to set things for another sip-provider or a different setup, it starts all over again, so what did I recently do ? I ….bought the …. Fritz!Box 7170 !
Also because I heard a lot of good things about this one, by users and also as a “by ISP provided device” (snooping around in the webinterface, I now see the point of that) (voip over ADSL…)
Follow the paperguide, that comes with the Fritz! (7170) and look for your “situation”
The box uses a weird looking cable to connect to your splitter, (or other if appropiate) it’s a ‘Y’ cable, that puts your telephone line connection and ADSL connection to one connector, that goes into the Fritz!Box, so you must read this carefully…but everything is marked…
Dont get confused because the landline connector gets mentioned seperately in “the story”‘,
I guess this makes the Fritz!box also compatible in other configurations…. once the hardware is installed, you put in the disc that comes with the Fritz! in your pc drive, and fill in your ADSL inlog info…and the …MySipSwitch inlog account info at “Internet Telephony provider, and you’re up and running,
All phone calls will now go through the internet, exept the emergency numbers.
After this the real fun starts…and you can make it very fancy ! 
if you want to go that far,
But i guess most of it you will manage from MySIPSwitch,
Use your dialplan settings as always, at MySipSwitch.
Set the Fritz! in “Expert Mode” to see all features and settings, you now should snoop around in the Fritz! web interface, and use the help function, to see what’s possible with that particular function…It’s all reasonably clear to use unlike with the SPA3102, which i found “a bit tricky”
