Can't make video call and voice call between Skype Personal and Skype for Business ( On - prem ) RRS feed

  • Question

  • Hi,

    I have a problem with voice call and video call between Skype personal and SFB.

    The condition at my SFB Envirotment:

    1. I have SFB Enterprise Pool with 3 Frontend Server.

    2. One SFB Edge Pool with 1 Edge Server

    3. Already configure SFB Federate with Skype personal. I can search the Skype Personal User from SFB vice versa.

    4. Already open port communication based on https://support.skype.com/en/faq/FA148/which-ports-need-to-be-open-to-use-skype-for-windows-desktop


    Although the port mentioned in the above url opened are still unable to make video call and voice call between Skype personal and Skype for Business. Based on Network Monitoring Application there are some port that must be opened other than those mentioned that is 10000 up to 49000.

    1. Anyone here have a reference about this port ?

    2. Someone here can give me diagram flow comunication between Skype Personal and Skype for Business ?

    Thanks.

    Indra

  • Hi Ekenk,

     

    To further troubleshoot the issue, Please confirm the following information.

    1.Can external users make a A/V conferencing with internal users with SFB client ?

    2.When you join the meeting, do you have some error messages ?

     

    You can use remote connectivity analyze tool to make a test .

    https://testconnectivity.microsoft.com/

    please double confirm the port 5061 is open.

     

    1. Anyone here have a reference about this port ?

    A/V conferencing  must open the port 50,000-59,999(TCP) ,port 3478(UDP) in the edge pool.

    Skype Connectivity Configuration with On-Premise Skype for Business 2015 must open the following port.

    2.Someone here can give me diagram flow communication between Skype Personal and Skype for Business ?

    If you have some doubts about the Skype Connectivity Configuration with On-Premise Skype for Business 2015, the following document is for your reference.

  • Again, please confirm you also went to https://pic.lync.com to register, this may be the exact issue if you haven't signed up yet that will very likely be the issue.  This is the provisioning site for Skype to Skype connectivity, without it you'll have issues, it's more than on-premises configuration.

  • Hi Ekenk,

    Have you changed the A/V port,use the cmd to check the conference server port .

    Get-CsService -ConferencingServer | Select-Object Identity, AudioPortStart, AudioPortCount, VideoPortStart, VideoPortCount, AppSharingPortStart, AppSharingPortCount

    The default port values are configured like this.

    Property

  • Hey Ekenk,

    the call establishment between SfB and Skype should be the same as with a federated partner. The Clients will go through the normal ICE Connectivity process and discover their possible candidates, do the Connectivity Checks, etc.

    As the others mentioned Port 5061 is important for federation and will be used in case of signalling, IM, Presence, etc. between SfB and Skype.

    There are no additional ports for SfB to Skype A/V communication to configure. When external and federation is working ok, thats it. So we may have to take a deeper look into the call flow to investigate the error. Maybe there is s.th. missing.

    The Parameter "EnablePublicCloudAudioVideoAccess in the "ExternalAccessPolicy" is set to true, right? If not, the Audio/Video Call button should be greyed out.

    Could you tell me please what happens when you try to establish a call?
    Does the signaling is working fine and after accepting the call on the other site the call will fail?
    Could you try the following - Both Clients (SfB and Skype) are in the same network (Maybe two notebooks next to each other) and please establish a call between them.

    In this case the Clients should use the host candidates and talk directly to each other. So we have a simple AudioCall scenario and dont use the edge server for media traversal or the NAT Device. 

    Could you provide us some information about the error from SfB Client Log?

    thanks for the answer!

    Greets,
    Markus
