<p>Hi people.</p>
<p><br>
</p>
<p>Thank all of you very much!</p>
<p><br>
</p>
<p>I need read more and more about the use of SIP in the industry. This will serve as complementary information that I will present in my next class.</p>
<p>So, i will search about that "<span>European standard for live radio broadcast</span>" and also about that "<span>standard for air traffic communication, connecting radio masts to a flight control tower</span>". These sound very interesting.</p>
<p><br>
</p>
<p>Here, where I work we are developing a intercom (door bell) for a company specialized in residential security. The intercom will have the OpenSIPS inside. As a SIP proxy, such intercom will connect the house with smartphones, for example.
<br>
</p>
<p><br>
</p>
<p>OpenSIPS is really helping me a lot! Because several project requirements I have programmed inside the opensips.cfg configuration file.<br>
</p>
<p><br>
</p>
<p>Thanks for the support!</p>
<p><br>

The questions your are asking are hard to answer and the Open Source world is most of the times opaque when comes to who is using and how much is used. As anyone can simply download and start using (information on how to do it) is quite enough, you may have
many cases were companies do use an Open Source software without "leaking" or "leaving traces" about that.<br class="">

Yes, I agree. These kind of questions are really hard to answer. During the last ten years, acceptance of Open Source in production use for</div>
<div>commercial companies have changed worldwide. Open Source proxys like OpenSIPS and the relatives (SER, Kamailio) and other code bases</div>
<div>like resiprocate are taking the market together with media servers like Janus, Asterisk and FreeSwitch.</div>

This is also for OpenSIPS project - it is hard to say who is using and how the popularity is fluctuating and mainly because there is no much of a feedback (as it is free to use).<br class="">

The interesting part would be Open Source platforms vs commercial and non-Open platforms. But no, I am not either aware of such data.<br class="">

If you widen the scope to “Open Source proxys” I would say that SIP as a protocol is making headway in interesting</div>
<div>areas. SIP is part of a European standard for live radio broadcast. It’s also part of a standard for air traffic communication, </div>
<div>connecting radio masts to a flight control tower.</div>
<div><br class="">
</div>
<div>I’ve built solutions for both of this standards with Open Source SIP software.</div>
<div><br class="">
</div>
<div>So it’s no longer just about “telecommunications” - SIP and the open source software is starting to deliver on</div>
<div>the original SIP vision - a realtime communication platform for Internet users.</div>
<div><br class="">
</div>
<div>To stay in telecommunications there are many presentations from our various conferences that will</div>
<div>give you ideas on where and how it is used. The new black is of course Open Source mobile network</div>
<div>platforms - after ISDN and SS7 this is the new interesting area to cover with Open solutions.</div>
