Users could login using a mobile from our external network without any issues. However, while the users are connected to Wifi in our internal network, mobile devices are unable to login.

Skype For Business Server Mobile Client issue

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

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.

Conferencing Software
