Skype 2015 pstn hybrid voice with O365. voice problem since last maintenance (KB3061064 + reboot) RRS feed

  • Question

  • Hello,

    i have a strange error.

    since last update and reboot, i cannot complete call (mobile to O365 client only, the O365 to outside world work well)

    the infrastructure is onprem skype 2015 with hybrid voice. all worked before.

    when user are homed in O365 user can't hang on (establishing call), and the caller (the mobile) continue to ring (waiting for call)

    when user are homed in onprem server, all is working.

    all trace say the same think, there is a sip protocol problem.

    the sip provider said that this probleme is a Skype problem

    red trace is mobile to O365

    green trace is mobile to onprem

    could you help me to brainstorm with this case ? the cancel is a manualy cancel

  • Hi Olivier.be,

    Based on your description, I understand that the users homed on Office 365 can’t make PSTN calls to others, right?

    All users in Office 365 had the issue or specific user had the issue?

    The issue is appeared after you install the KB 3061064?

    Which product did you use for reverse proxy?

    For this, please make sure you have correct configure for Lync PSTN hybrid, for details, please refer to the link below
    https://docs.microsoft.com/en-us/skypeforbusiness/skype-for-business-hybrid-solutions/plan-your-phone-system-cloud-pbx-solution/plan-phone-system-with-on-premises-pstn-connectivity

    Moreover, you can collect logs on SFB edge server, check if there are any clues.


    Best Regards,

  • Hello,

    all o365 users cant receive pstn call. but can make pstn call.

    all my 3 tests users have this problem

    the issue is appaered just after the KB installation. before, calls were functionnal

    for reverse proxy, i use iis ARR.

    perhaps the configuration lost something when the maintenance was done. but before, it was working.

    then i fell the configuration is correct. (i followed the docs.miscrosoft as guide to do)

    i will gather more log

    thanks already

    Olivier.

  • Hi Olivier.be,

    I notice this issue seems occur after you did an update. I suggest you could first check the Skype for Business CMS replication status to see if all is True. You could run this command: “Get-CsManagementStoreReplicationStatus” on Management Shell.

    According your description, only incoming call to Online user has this issue, please check the Event Log on Edge and FE server side to see if there is any related information about the failed call.

    You could also refer to the sip flow according the following article:

  • (only if i call from mobile to O365 hybrid psnt, o365 homed user)

    I uninstalled the KB, and rolled back server before kb installation.

    and i still have the problem

    this is strange, if i check de client, i saw the 200 Ok of the hank on:

    in my mediation server, when i trace, i dont have this "200 ok" as this picture show it

    no ok after 183 session progress.


    if i call from my mobile to this o365 homed user, and when this user aren't loggued -> voice mail , and i receive 200 OK
