The 1.2 version of SIPSorcery is suitable for running on a standard PC on an average broadband connection. Since the previous 1.1 release the main feature added has been the GoogleVoiceCall application. Under the hood there have been a number of improvements and Microsoft SQL has been added as a storage layer option. The use of the DbLinq library has been removed which makes a big difference to performance. A range of other updates to the core SIP stack amongst other things are also included in this release.
