JoinConference with the Lync 2013 client SDK in UI suppression mode

Question

I'm working on a project that uses the Lync 2013 client SDK in UI suppression mode to show a custom UI for Skype. I am able to call the ConversationManager.AddConversation() method and connect to IM, audio and video just fine for 1 on 1 calls.

Now, I would like to call the ConversationManager.JoinConference(conferenceUri) to join an online meeting. I am using the uri for a scheduled meeting and I format it like this:

conf:sip:aweston@meet.dev.domain.com;gruu;opaque=app:conf:focus:id:6OHB2XXX?required-media=audiovideo

The call seems to connect but after going through some state changes it just goes to Disconnected.

If I join the same meeting using the standard S4B client, the meeting connects just fine so I think the meeting and the connectivity is all setup and working ok.

I have looked for samples on how to do this here …

https://msdn.microsoft.com/en-us/library/office/jj933140.aspx

And also in the SDK here … C:\Program Files (x86)\Microsoft Office 2013\LyncSDK\samples

I'm starting to look at the S4B logs here … .\AppData\Local\Microsoft\Office\15.0\Lync\Tracing

But I'm not really sure what I 'm looking at there.

Here is a log of the calls that I'm making. Any suggestions or samples you have that are doing a similar thing would be most appreciated.

Thanks

Your conference link suggests that audio/video is required but your log is showing that there is no Audio or video devices connected. Try the following conference link remember to include the ? at the end conf:sip:aweston@meet.dev.domain.com;gruu;opaque=app:conf:focus:id:6OHB2XXX?

Thanks Paul, I tried your idea, same result. After JoinConference, in the Conversation_Added() event, I'm not sure what to call, I've tried AddParticipant and BeginConnect but I keep getting Connecting ... disconnected. – Andy Weston Sep 21 '15 at 17:15
You shouldn't need to do anything, calling conversationManage,JoinConference(conferenceuri) should be sufficient. Are you handling any of the events of the resulting conversation and if you are how so? – Paul Hodgson Sep 22 '15 at 07:18
I'm seeing the ParticipantAdded event for myself but that is all. The modalities are all disconnected. If I join the conference in the S4B client with a second user, it seems like I have 2 separate conversations. – Andy Weston Sep 23 '15 at 13:01
It's a long shot but recently I have seen anti virus software affecting conference joins (Norton in particular) is there a chance you can disable your anit virus briefly just to rule it out? – Paul Hodgson Sep 23 '15 at 13:26

I turned on Windows Event Logging and I got a good error message from my request: **ms-diagnostics: 1065;reason="Federation is disabled"**. I'm looking at server side configuration now but I'm wondering why the S4B client works fine but my API call fails. – Andy Weston Sep 29 '15 at 13:28
Did that message also include source and domain values? It seems odd that you are getting federation issues here and not in the normal client. – Paul Hodgson Sep 29 '15 at 13:55
Added error details ... this is a dev environment that was recently setup for us. – Andy Weston Sep 30 '15 at 17:23
Success! The keys to making this work were 1) adding that lone ? to the end of the link, 2) stripping "meet." out of the domain name when calling the API, and 3) enabling Federation in the S4B control panel on the server, thanks! – Andy Weston Oct 07 '15 at 02:22
