SylkServer Lync Gateway¶

Goal¶

The goal of this project is to develop a software gateway that makes possible end-to-end interoperability between Microsoft Lync, a proprietary solution based on modified IETF SIP standards and foreign domains using XMPP foundation standards. The solution would then be used for federating real time communication services using multiple media like audio, chat, presence, screen-sharing, video and file transfer between these Lync, SIP and XMPP protocols. This would allow parts of an organisation to migrate away from using a proprietary solution while maintaining interoperability with other parts of the organisation that still make use of it.

Features¶

The gateway will provide translations for the following media:

• Audio calls
• Chat conversations
• Presence notifications
• Screen Sharing (using Remote Desktop Protocol)

End-points¶

The gateway will be inserted between two foreign domains, allowing each domain to use its own client to interoperate with the client in the remote domain. A Lync based domain will use a Lync client and an XMPP domain will use a modified XMPP client that is able to support audio calls using Jingle and screen sharing using RDP protocol. It is the responsibility of the customer to develop its client to support these standards.

Testbed¶

The customer will provide a functional Microsoft Lync implementation both clients and servers and support for troubleshooting issues related to native Microsoft implementation.

Delivery schedule¶

The delivery of the above mentioned features will be done over a twelve month period. After six month, a functional skeleton of the application will be available and two media types will be implemented. Other media types will be subsequently added.

h3 Costs

Costs consists of one time development fees and subsequent recurrent support fees. 1st year support period is mandatory, support may be cancelled after 12 months.

• The development costs are 7000 Euro/month. The total costs of the project amounts to 84000 Euro.
• Support fees covers software upgrades and troubleshooting for problems reported by customer. The support fees amount to 18% of project value for the first year and 12% for subsequent years.
