Kamailio (SER) SIP Server v4.2.0 Released!

#Kamailio (#SER) #SIP_Server

It is hard to believe that it was 14 years ago that we got to play with SER 0.8.x but certainly the server has come a long long way. Looking at the release notes, this is a major release of Kamailio SIP server, as the development team mentions. OpenHub has attributed 250 man years of development by a massive development team. The commits to main branch alone accounted for 20,000.
