It seems like audio video uses ports 50000-59999. Are these the same OCS 2007 uses? Is there a way to force Lync Attendee to use a smaller range of ports from this set? I cannot access the link above.

Solution worked. Also, A possibility of using their Edge Servers to establish communication instead of their A/V and FE servers.

We currently have OCS 2007 working with a federated partner and have no issues. They are migrating to Lync and we are installing Lync Attendee to continue meeting with them. There is a problem within Lync Attendee where the audio does not work. With OCS we have 50010 thru 50100 allowed. Are there different ports needed to get audio working in Lync Attendee? Not sure if it matters but we can get audio in Lync meetings by using OCS. Thanks!<br />

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).

Chat / IM

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Web conferencing describes various types of online collaborative services including web seminars ("webinars"), webcasts, and peer-level web meetings. In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers. Popular titles include GoToMeeting, Cisco WebEx, Microsoft Lync, TeamViewer and Skype.
