Hi,

After migrating to Lync 2013 from Lync 2010 we are Unable to Chat/Call with more than 1 person at same time over Lync. Please let me know if any other info is required. In Lync 2010 environment it was working fine.

Hi

Please check your conferencing policies in Lync 2013 to make sure the maximum participants allowed is not set to 2. You can raise this value to 250 in a supported way.

thanks

Hey Mark,

The current policy is set to 10 users but still not able to do a chat/call more than 1 user.

Hi,

Did you see any Lync error message on SFB FE Server Event Viewer?

Did the issue also happen for users who initially enabled on SFB Server but not user who migrated from Lync Server 2013?

If the issue only happen for the migrated users, please make sure CMS replication update to the latest version.

Please also delete SFB user profile and information on registry and then test again:

%UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync
HKCU\Software\Microsoft\Office\15.0\Lync\sip@domain.com

Hi Eason,

I tried that but no success still the issue persists. Yes the issue happens for both migrated and users enabled on SFB server.

Check the topology builder and locate the pool, is conferencing enabled on the new pool?  Are all services on the new pool's server's started?

Checked conferencing is enabled on the new pool. Also all the services are started.

What is the error you see?  What is the user experience when they try?

no error comes up. But when someone add three people in a conversation no ones get the messages. And in conference call error comes up call has not been ended or not completed.

Have you restarted the server/pool? 

If that doesn't make a difference, I'd run the OCSLogger and watch sipstack, see what happens when the users attempt to send messages to each other in a conference.

Is OCSlogger available for SKB server?

Yeah kindof/sortof if you don't want to go full CLS: http://www.ucguys.com/2015/05/skype-for-business-server-debugging-tools.html

ok thanks will try that.

Hi, if you run the following cmdlet from Lync Server 2013 PowerShell:

Get-CsConferenceDirectory | FT Identity,ServiceID

is it pointing the ConferenceDirectory to your Lync Server 2013 Pool?

Also, please make sure that your Certificate assigned for Lync Server 2013 from Deployment Wizard (Step 3 ) has been "Enable for all purposes".

Hi,

Yes I have checked both and they seems to be in place. When I am adding third person to IM chat after few seconds that person automatically vanishes. I don't why this is happening.

Please if someone can help. This issue is killing me!!!!

Hi,

Please check if the issue happen both with the Lync conference and a normal Lync IM/Call (initial two users, then add another user).

Make sure Lync Server 2013 update to the latest version.
