skype for business desktop sharing not working

When the call is placed the window opens and it just hangs in there saying 'calling' but nothing happens. Problem is that cannot make or receive 'skype (for business) calls' to/from other Skype for Business users, either internal or external. I've also tried this using my Voda phone handset as a hotspot and I get the same problem.Īny ideas?. Text chat is working just fine, including sending and receiving images and desktop/screen sharing. My neighbour let me test it on his wifi, which is copper based broadband, 2km from the exchange (max 6meg) and it works there every time.ĭo you know why this is? It's like there's a port blocked at the mast or something. I've been trying again later for 3 months now! Very occasionally it works (<1% of the attempts). I get the message: 'We couldn't connect to the presentation because of network issues.

across multiple computers.īut the one thing I can't do is present desktop / see colleagues' desktops over Skype for Business. The Skype meeting works fine and audio is no problem.

I have a rule setup to allow all traffic from our Workstation subnet to the Internet. This started when we migrated to our Sophos XG 210. This usually happens when S4B has been running continuously for a long period of time (think many days or even weeks) and/or when Skype. I have an issue with Skype for Business screen sharing when connecting as a guest to another organization's meeting. IT works fine for everything, including Zoom, Skype, Skype for Business etc. We’ve seen a large number of cases come through recently where application sharing with 32-bit Skype for Business 2015 and 32-bit Skype for Business 2016 clients (collectively, S4B) is failing intermittently.

I get decent speeds out of this most of the time: above 10meg. My home network runs uses a Voda 4g data sim in an industrial 4g router, attached to two 1.5m directional 4g aerials pointing at the local Voda mast 2km away.
