pjsip blog

Follow Medhavi Bhatia as he went through “a 6-month ordeal” reviewing sipX vs reSIProcate vs pjsip. The main reservations he had was our default free software license (GPLv2) which he found “restrictive” and the fact that we are not widely known or deployed. Also we have a smaller community.

Those are fair points to raise:

• If you don’t want to use pjsip under GPL, please contact us.
• Usage and deployment: at the moment we probably have around 20 or so applications that we know about. Being free software, not all GPL users notify us.
• On community size, I can’t say whether we are small or not as we don’t have data on sipX and reSIProcate. Here are our stats:
  • Over the last 6 months, we had on average of 950 downloads per month.
  • Mailing list membership fluctuates of course, as users come and go. A conservative estimates would be around 300 members at any one time. We also have stats for mailing list posting rates.

In the end, it was the fact that pjsip was more “malleable” and suitable for their team’s long term goal that made them decide on pjsip. And the fact it was his gut feeling from the very start anyway…

Thanks for sharing your evaluation process, Medhavi. Making technology choices are never easy, especially the decision to use other people’s framework (programmers always like to DIY; I know because I use to hate being forced to use other peoples code!)

Have you ever evaluated pjsip or any other free and open source SIP and media stacks for Windows, Mac OS X, or other platforms? We’d love to hear them!
