[Matan Barth is a Project Manager in our Global Services group. Since he is working on several projects that deal with IP PBX technologies, I've asked him to provide his views on this subject. As a result he'll be posting a series of posts on media relay. This is the first installment in the series.] To relay or not to relay – to paraphrase Shakespeare - is a decision that may well be as important as “to be or not

In a previous post I asked if XMPP is going to be a successor of SIP and that has brought a lot of attention and a new nickname to me (Radvision guy), which I gladly bear in honor after 10 years at RADVISION. That said there are few things that need to be stated about SIP’s complexity and XMPP’s clean architecture. To better show and explain the complexity that is involved here, I will show you a graph that was

SIP today is a standard-de-facto, “The Protocol” which runs our multimedia communication. I believe nobody would argue with this statement. All the vendors have their SIP based equipment in the field, so considering the level of maturity of the protocol (about 10+ years old) and more than 20 SipIt events -(SIPit IOT events) as well as numerous IOT events by other consortia and standard bodies, we can expect that majority of devices on the market are highly interoperable.
