I was having some internal discussions when one of my bosses told me that he heard from one of his acquantaince who works for company X that their SIP implementation is light years ahead of their competitions. That ticked me off.
I hear similar claims from lot of the big companies like Avaya/Cisco/Nortel and it never ceases to amaze me their lack of understanding especially when it comes to SIP. SIP now no more is a techie’s delight. It has become a marketing weapon and claims on who has got the better SIP seems to be the order of the day rather than a prudent discussion on what can SIP do for the world. And yes I am disappointed that SIP is today being misused like this.
Anybody saying that their SIP is better is like me saying the electricity I have in my house is better than my neighbor’s!!! It is that ridiculous. What matters are the devices that “electricity” powers. SIP is the same, the greatness lies in the seamless effort taken for the devices which it empowers to communicate with.
For an open standard like SIP, greatness is measured by how many devices your stack has interoped with and the track record of Cisco/Avaya are dismal. If I were to pick a good SIP stack it would be openSIP. They outclass everybody else wrt to interop and they are by far the best when it comes to performance They were earlier called openSER and at that time when I used them they could do I think a million calls in BHCA!!!!! Oh, did I mention they are open source?
This is my grouse. We have been communicating donkey years (TDM included) and nobody really cared what the underlying signalling protocol was. Why is there a new found respect for SIP (which is just another signaling protocol) and why are these companies fighting over this? What this essentially shows is that innovation has come to a grinding halt and there is nothing else the top companies are able to boast about. Hence they are harping on something as mundane as “we have the better SIP”.
Anyway, SIP is old and so retro and the techies have moved to other things. Perfect example HD VoIP. They use SIP as well. In fact I read an interesting thought by Pulver that these HD devices should be identified by the SIP URI. You don’t see him talking about SIP per se. Reason is SIP in essence is just a platform and historically users never care about platform. They care about what they can experience or the solutions that these platforms power.
Any discussion on superior SIP according to me is meaningless and shows the lack of thought leadership in the companies that run these kinds of campaigns.
