Microsoft Lync replacement checklist¶
AG Projects was closely involved with menthor-ship, authoring and developing of software in the public domain for the specifications emerging of SIP SIMPLE and STOX IETF working groups. AG Projects has implemented all applications beyond VoIP that complete a SIP deployment to compete with commercial offering traditionally available from closed vendors like Apple, Google and Microsoft. The software building blocks can be used to implement a complete multimedia rich communications with audio, presence, chat, file transfer, screen sharing and video based on SIP protocol. An end-product based with these capabilities will compete with Skype and Google Hangouts for residential customers and Microsoft Lync for corporate customers, the later being the current focus.
