The pros and cons of Internet phones


INTERNET PHONE GLOSSARY 
CALEA - A 1994 act that requires telecommunications services to provide wiretapping access. The act specifically excludes information services, so the question is whether VoIP is a telecommunications service, and thus covered by the act, or an information service, and thus exempted. VoIP providers are receiving pressure to comply with the act.

PSTN - The network of wires, signals, and switches that lets one telephone connect to another anywhere in the world. Some VoIP services provide a gateway from the Internet to the PSTN and vice versa.

SIP - Communication protocol that operates similarly to H.323 but is less complex and more Internet- and Web-friendly. Fully modular and designed from the ground up for functioning over IP networks, it can be tailored more easily than H.323 for Internet applications. SIP and H.323 can and do coexist.
