If that itself isn’t working it for sure will cause problems with UM online and VM. The Call flow of FE/Edge sending the call to exchange Um is similar to the call flow of a LYNC call between internal and external or internal and federated users. Make sure internal users can Successfully make and receive LYNC calls to federated users and remotely connected users. If you do not have Open federation you have to add someone’s Domain to your allowed list and then try and see if you can establish IM sessions with this domain. Have a Internal user establish an IM session with a federated user (If you have Open federation then they should be able to add users from other organizations who have open federation. Have a User sign into LYNC remotely through the edge In order to confirm that your edge server is configured correctly make sure you can do the following: Make sure you have a working LYNC Edge server. The Procedure to Configure this is Described Below:Ī Working Edge server is a Requirement for LYNC on Premise to work successfully with Exchange UM Online. The exchange Online UM server verifies the tenant, checks Dial Plan, Then Checks the "Callee" Info from the Invite and validates if the "Callee" user has been enabled for VM in O365 and if he is then it accepts the VM Once Edge sends the INVITE it reaches the Microsoft access edge proxies which relay this to the Exchange online UM servers in O365 The CShostingProvider points to exap.um. and hence edge creates an INVITE and sends it out to exap.um. The Job of FE server is done at this pointĮdge server checks the CSHostingProvider to see if a Hosting Provider has been created for "Exap.um." to find out if it should send the call out to O365 Once it finds that the call needs to go to Exchange Um Online (Exap.um.) then it generates a new Invite and sends the call to the Edge server. The Hosted VM Policy should point to the customers Tenant in O365 and exap.um.
If it is, then it checks the Hosted Voice Mail policy that is applied to the user and finds where to send the call. The FE server Checks User B’s Hosted Voicemail Attribute to see if HostedVoicemail is set to $TRUE LYNC FE server Now has to decide what to do with the call How Does it Work - Call Flow for a Voice mail callĬall then goes back to the LYNC FE server Integrate LYNC/SFB Server on premise with O365 Exchange UM onlineīefore we get into this, we need to have a basic understanding of what's happening with voicemail. Below is a Brief Description of what happens in the background when a call is being routed to Exchange UM online for voicemail. First published on TECHNET on Mar 29, 2016
