Microsoft Lync replacement checklist¶
AG Projects was closely involved side 2005 with menthor-ship, authoring of specifications and developing of software in the public domain for the deliverables of SIP SIMPLE and STOX IETF working groups. The software implements SIP applications beyond VoIP that can complement existing SIP deployments so that they can compete with feature-rich commercial offerings, traditionally available only from closed vendors like Apple, Google and Microsoft.
These offerings typically provide a rich multimedia communication experience with audio, presence, chat, file transfer, screen sharing, video and multimedia conferencing for all media. An end-product based with these capabilities will compete at equal footing in terms of features but a lower cost with Skype and Google Hangouts for residential customers and Microsoft Lync for corporate customers.

Presence Agent (RLS) is provided by OpenSIPS, MSRP NAT traversal by MSRPRelay and Contact List by OpenXCAP. Ideally, these components should be integrated in SylkServer in case the solution should be deployed at customer premisses.
