I'm đang check log according to your instructions and found log : Thanks Akampa.i'll reply for you to later To each one no problem.when created gorup voice or video warning "You have left the call".web meeting sameness.Virtual machines DC, SQL serve, Skype for business (Enterprise) - not Edge server - opened ports for SFB,from internal DCĪnd External Internet everything is OK,problem is Group call and Group Video and Conference.so crazy 4 days I can not find the cause of this problem .Thanks you so much Akampa.Thank you so much to everyone who has supported me. If from external internet chat,voice,video Machine.sign in Skype for business and create meeting conference with 3 participants ,but cannot voice or video cause' need an setup audio device so i can't know voice,video,conference activity with many people. I tried it, but Skype was still using random ports.I'm glad you answered,virtual machine tax in Amazon cloud.i've a static IP and created DNS record pointer IP address SFB,open port,user could auto signin,get address book,send file.v.v.in DC or external internet.And now i'm only remote desktop to virtual Third option, but it didn't work for me: you can specify a custom port in Skype connection options, then eventually authorize it in your policies. If you don't want to allow those categories in the webfilter, skype will be blocked on standard ports and will use a RANDOM port to connect, so you must open ALL ports in your policy (since it's impossible to guess which one will be used) in order for the Skype to work. If I block "Security Risk" category -> not working ! Even worse than that: putting the categories on "monitor" also seems to block skype calls ! You must select AUTHORIZE.Ĭonclusion: Skype calls are blocked by the webfilter.Īllow skype to connect on standard ports by authorizing all websites in the webfilter, since it looks like skype is blocked in multiple web categories.
Then apply, wait a few seconds, boom: Skype calls are working ! If I block pornography websites -> Skype is not working. My only option if I don't want to open all ports on my LAN policy in order for random Skype ports to work is to AUTHORIZE ALL WEBSITES IN THE WEBFILTER. All ports being open in my GUEST policy: CALLS ARE WORKING ! And the random port not being allowed in my LAN policy -> Skype calls are not working.įor the users under the GUEST policy, Skype is also blocked by the webfilter, then use another random port. After reading Skype documentation, i know that if Skype is blocked on standard ports (80 or 443), it will use a random port to connect.įor the users under my LAN policy, Skype is blocked by the webfilter, then use another random port. Logs are telling me that on BOTH policies, Skype is blocked by the webfilter. The only difference is: LAN policy only has a few ports open, while GUEST policy has ALL ports open. Both policies are using the SAME webfilter. I have 2 IPV4 policies for 2 types of users (let's call them LAN and GUEST). I investigated a bit and I found the culprit: webfilter. I had the same problem on a Fortigate 90D: Skype chat works, but not calls.
