In this blog article we will discuss the basic standards used for real-time communications — SIP and XMPP — what is the difference, how each of them works, and, which one to choose.
SIP and XMPP
The IETF has two documented standards for real-time communications that are widely implemented: SIP and XMPP.
These standards transport text information and rely on other standards for the actual media transmission.
As both support real-time communications, many question which solution is most suited to their needs.
Let’s briefly explore the history and purpose of both.
Years ago when VoIP first appeared on the scene, in the time of dial-up Internet, it was associated with poor audio quality and dropped calls. Today it is no longer a problem, thanks to the increased availability of broadband Ethernet services. Large and small companies, public administration organizations worldwide opt for VoIP, while some other enterprises are still hesitant to make the move.
It might be just the right time to learn more about VoIP technology and SIP trunking: the largest telecom providers all around the world stop offering ISDN and PSTN in 2018 and have announced complete phasing-out over the next ten years.
