    Hi,

    Running Skype for Business 2015.

    We have an issue where external skype clients can no longer connect, no idea when this broke, external skype is not heavily used.  No issues with smartphones or the web app.  Running a few powershell commands I have come across the following:

    AccessEdgeInternalSipPort     : 5061

    AccessEdgeExternalSipPort     :

    AccessEdgeClientSipPort       : 443

    DataPsomServerPort            : 8057

    DataPsomClientPort            : 443

    MediaRelayAuthEdgePort        : 5062

    MediaRelayInternalTurnTcpPort : 443

    MediaRelayExternalTurnTcpPort : 443

    MediaRelayInternalTurnUdpPort : 3478

    MediaRelayExternalTurnUdpPort : 3478

    MediaCommunicationPortStart   : 50000

    MediaCommunicationPortCount   : 10000

    Since AccessEdgeExternalSipPort doesn’t have a port associated with it, could that be the problem?  If so how do I go about adding the port?

    I also noticed in the S4B control panel, under topology, the edge and application server, the status is not available. Is this supposed to be like this?

    TIA

    Thanks Sharon,

    That's it!  Funny how it doesn't say anything about edge on the command line but federation in the gui.

    Thanks.

    Hi Email Relay,

    In Skype for Business Control Panel, the normal status of Edge server is N/A.

    In our environment, AccessEdgeExternalSipPort has an associated port as the following image.

    

    You can execute the following command to set port for AccessEdgeExternalPort:

    Set-CsEdgeServer -Identity "EdgeServer:edge.domain.com"  -AccessEdgeExternalSipPort 5061

    Best Regards,

    Hi Sharon,

    Thanks for your reply.

    When I try to use that command I get the following error:

    Set-CsEdgeServer : Cannot add ports in this manner. To add ports, you must use Topology Builder.

    So I will try topology builder and see how it goes.

    Hi Sharon,

    Sorry for the tardy reply.

    So I looked around the topology builder and I don't see anywhere to adjust the AccessEdgeExternalSipPort setting.  Where can this be adjusted?

    Thanks.

    Hi Email Relay,

    In my research, AccessEdgeExternalSipPort is related to federation. After I enable the federation option as below, the port will be set as 5061 in the command.
