Legal impacts

VoIP providers could not even with a new equipment to reach anything that offers a Public Switched Telephone Network. One example - the problem with calls to emergency services. VoIP does not have geo-referenced, so it is impossible to determine the place where it is used VoIP, to transmit a signal to local services. As a compromise, such providers redirect calls to the city's telephone network. But if I travel and I called over my laptop from another city, the call is transferred to the emergency services in the community. If, moreover, I can only say a few words - I have no chance of success.

Also, as the police department responsible for security, according to the law should be able to listen calls. With VoIP is not very easy.
