when testing - are participants local or remote?
You need access through EDGE server from remote, what are your settings for AV interface on Edge server in Topology builder?
is the DNS record valid
have you configured public IP-addresses on Edge og are they NAT'ed through firewall?
If you've used NAT'ed addresses, are correct public IP configured in Edge server for AV NAT?
Are firewall open to AV Interface address

Hi Jakob

right now i just want to test the features internally

i have no Edge server all i have SFB front server

the test i am doing right now just with our internal AD users within our internal network

and my point when i try to share application with one user it work when i invite another user i cant share application with him

so my point cloud be policy issue ?  or youthing i need seprate server to present application with multi users in the same session ?

just tell me how can i start my check to find out the root cause

as i told you i want first to test everything within our internal users then i will install external access

we are just test Skype for business

thanks a lot

no firewall just we have proxy

but my point why this feature work  with one to one  but dose not work  one to two or three

i main when i establish session with one user i can share application with him so when i invite other user and i try to share the application with him i got this error

so i thought about policy because it worked with one but not with two

what you think

using one to one is peer-to-peer. When accessing mulitple users the conference is moved to Front End server.
can you bypass proxy. need TCP 8057 to front end server
