I have wanted to write this post for a while. For a long time I have been concerned about the competitiveness of the SER/OpenSER eco-system in the larger SIP picture.Let's look at the big picture: SIP has been established as the preferred signalling protocol for real-time sessions like voice and media. It bears the characteristics of other open technology systems like TCP/IP … [Read more...] about Competing eco-systems, IMS, SER, Asterisk, who will win?
