External callers don't hear ring tone when calling our Skype users.

    Question

  • We use Skype for Business 2015 with a sbc that sends calls to Interactive Intelligence and to Skype for Business.

    External callers don't hear a ring tone when calling any of our Skype users numbers.

    Internal calls are fine and you can hear the ringing tone before a user picks up.

    What could be the issue?

    Thanks

  • Link user graded out,

    Could you post a log from your SBC for an active call? This will help us determine what the issue is with ringback. Also what SBC are you using?

  • Hi link,

    Did this issue happen to all users in your environment?

    If the issue only appeared on the specific user, please try to compare user attributes in AD between the affected user and other normal users. If the issue appeared on all users in your environment, please try to check the configuration of the enterprise voice, the following document is for your reference:

    Make sure your mediation server with the latest update. If the issue persists, please try to use SFB debugging tool collect more information for us.
