WebEx Room Kit with WebRTC allow Microsoft Meettings ≠ Domains

[dsobrinho]

Hi team

Does anybody knows if WebEx Room kit configured to use OBTP with WebRTC allow receive invitation from external domains and including the email address of the WebEx Room Kit (via Calendar integration)?

Or

The OBTP with WebRTC works only for internal domains of the company?

Best regards,

[dsobrinho]

UPDATE

During my test when someone from different company (different domain Microsoft meetings/teams) sent a invitation and included the email address of WebEx Room Kit via Hybrid Calendar integration, the scheduled does not appear in the agenda.

However, when start a scheduled from internal domain (same domain as email of WebEx Room Kit) the OBTP and works and appear in the touch to join.

It can work but requires a non-default setting on the Exchange room resource mailbox.

Set-CalendarProcessing -Identity "room name" -ProcessExternalMeetingMessages $true
