As you all know, we are fans of pjsip, either directly from pjsip developers or through other developers who used pjsip, we have been using it for a long time and we are certain, we will use it much more in the future.
So we were very glad when they reached the version 1.0 but as the title reveal, they have not stopped at that. The continue to build upon and improve pjsip. To reach the pjsip 1.0 status, they worked for more that three years and gone through 250,000+ lines of code. There is also a growing community gathering around pjsip as well.
With the version 1.0, the team promise us that they will work with the mibile side of the development deligently. So look forward to mobile support starting with Symbian S60 and Windows Mobile.
Also a visit to Teluu, as the company behind pjsip, would be a nice geture. Teluu provides lternative licensing, direct developer-to-developer support, and customization work.
Here is pjsip's own announcement; "We Made It: Release 1.0.1 Available"
