Can Skype for Business/Lync 2013 act as a relay for Voicemail to the O365 UM? RRS feed

  • Question

  • Good Day Experts,

    We are facing an issue where one of out client is facing the following:

    https://techcommunity.microsoft.com/t5/Exchange-Team-Blog/New-date-for-discontinuation-of-support-for-Session-Border/ba-p/607853

    We have the following call flow currently:

    3rd party PBX  - 3rd party SBC - TLS - O365

    We are trying to validate if this is possible at all:

    3rd party PBX - SFB 19 (acting as a relay) - O365 UM

    Can someone from the esteemed panel confirm if this is possible?

  • Hi Himank Pande,

    It is supported, you could integrate SFB/Lync Server with Exchange online UM.

    The steps about the integration, you could refer to Integrate Skype for Business Server with Exchange Online Unified Messaging

  • Thanks Evan for the response.

    You could integrate SFB/Lync Server with Exchange online UM. - That integration already exists but what I am asking is as under:

    If a Phone extension exists on a 3rd party PBX and there is a corresponding User Profile on SFB/Lync, would this work.

    More specifically, if there is a 3rd party aka Cisco Call Manager has an extension on a phone say 9999871234 with a Remote Destination Profile associated to a Remote Destination which in essence sends the call to a SIP URI (say john.doe@contoso.com) on SFB and SFB is configured for John Doe with SIP address- sip:john.doe@contoso.com and has Line URI as tel:+19999871234;ext=9871234;ms-skip-rnl. The user is UM online enabled.

    Will there still be a configuration that SFB can have to accept calls from the Cisco Call Manager and pass it to the UM Online?

  • Hi Himank Pande,

    For the Cisco Call Manager integrate with SFB and Exchange Online UM, I suggest you could confirm with Cisco provider. 

    Thanks for your understanding.
