VON Europe Autumn will be held in Rome on the 26th and 27th of September, industry leaders from all over the world will talk about where IP communications is going in Europe. SIP, IMS, IPTV and Voice are all being covered at this event, along Open Source Telephony issues and perspectives.
It’s good to know the open source VoIP ecosystem is being discussed at a high profile enterprise conference such as VON. Asterisk and OpenSER are frequently used with pjsip, so anything that increases their profile we hope will increase the adoption of open source SIP implementations.

I really enjoyed to see so many open source projects within an event like VON. I believe it’s a clear sign that also in this area open source is getting ready-for-prime-time. Good news!
