SIP Service: IP Telephony

One of the most exciting services for SIP is for IP telephony.

Before SIP IP telephony solutions often used a protocol called H.323. UnfortunatelyH.323 has serious interoperability problems, is not designed for the Internet, and has shown itself to be limiting and too complex.

SIP is a much more streamlined protocol, developed specifically for use on the Internet. Smaller and more efficient than H.323, SIP takes advantage of existing protocols to handle certain parts of the process.

With SIP, IP Telephony can show global end-to-end connectivity, excellent scalability and compatibility and users call each other using email addresses. Using SIP, broadband Internet, better equipment and implementations, a break through for IP telephony is now imminent.
