Federation Tester

Federation is one of the key aspects to Microsoft’s Lync Server products, it enables users to connect to organisations outside of their own, using the internet, rather than breaking out over PSTN or ISDN lines to make calls. Lync federation allows for end to end user communications using IM, Voice, Video and Conferencing.

Setting up Lync federation is reasonably simple once an Edge Server is installed – for information on setting up Lync federation in your organisation, please refer to the Microsoft documentation.

Once you have Lync federation setup you can use the Event Zero Federation Tester to check if your federation is working correctly. Just click the “Test Now” tab above and follow the instructions. The Event Zero Lync Federation Tester can help you test both incoming and outgoing federation in both Voice and IM modalities.

Lync Federation Tester is a free tool provided by Event Zero. Feel free to use it as many times and as often as you like. Please also take the time to check out our other Lync Apps.
