I guess you're referring to ISO standards, PCI ditto and such. I see no real problem with having to pay for that. I can still use them without being dragged into court.
Some companies build their own, different technology, just for that reason, at the cost for the client or impossible interconectivity.
Talking of phones, Europe is 64 KBit/s channel, the USA is 56. The USA uses µ-law digitalization (companding algorithm), Europe A-law. International phone calls are not that easy to implement.
For the end-user, it's not an issue and I don't need to use the same phone (or technology) as my old mum when I call her. (except if I wanted to use Skype).
It is, or was, for instance, it you traveled with your modem and needed to connect on the hotel. Or if you set offices on different countries, you needed to get local hardware for the phones. Say... I don't know currently, but British home phone lines used a separate ring copper line, because that line was separated from the voice lines at the entry box to the home. So the plug needed that separate pin. I don't know if this has changed. But the British are different: for instance, they had different power plugs on houses. When I traveled there and bought a gadget, years ago, the power cord had no plug. You had to buy that separately and connect it yourself, after learning what your place used - which at that time were probably the same in all new houses. As I say, I don't know if this is still true. The European Union has enforced some standardization. Like increasing the voltage from 220 to 230 in Spain, silently. And conversely, lowering from 240 to 230 on others, I hope. Not sure about this.
Yeah, if only SIP was as popular as Skype.
Because it is not "click and shoot" install. Years ago you had to configure routers, it was not simple.
I agree, but I still wish it was. (I don't remember having to do anything special to a router though).
I do... NAT is a problem to traverse. Depends on your router. - -- Cheers / Saludos, Carlos E. R.
