After trying to connect to conference call/accept multiple call from other, call ended with error message:
Unable to establish a call
488 Not Acceptable Here
Error parsing SDP

Seems, that problem is in case, that meeting is already in progres, OR I accept invitation from other two persons in call who add me later on.
interesting, I used to participate in conference calls regularly and everything worked fine in the scenarios you've mentioned.
Error parsing SDP
Looks like we are sending some malformed requests to the conference server. Please send me your logs; use the same email like last time.
I tried to join to conference call of a Lync Meeting that resulted this same problem. Accounts -> Lync account -> Test Call reproduces the same error. Here is the related ms-diagnostics line from Pidgin log:

Hello, I have the same issue... When I try to join a conference call of the scheduled conference, it ends with this error:
"Unable to establish a call
488 Not Acceptable Here
Error parsing SDP"
There is a workaround or any patch to solve this issue?
I'm on Lync Server 2013 now and have also encountered the very same error while connecting to a conference. It should be fixed by this commit in mob so please try out the latest git version.
Wow, now seesm, that I'm able to join at least... I will test it more deeply and will let know. Great work! :)
Now just enable presentation and it would be absolutely great!
Hi, I tested it, but it doesn't work yet. There is some lines of the debug log (I changed the IPs and the users for dummy values):

unfortunately your log snippet doesn't provide any clues as to what's going wrong in your case. Please try attaching complete Pidgin log (obfuscate any confidential strings as you wish).
What version of Lync server is this?
I guess log from original Lync client doing the same action would be most helpful here, though. Please see how to create it.
@reporters: please compile git HEAD and confirm that the problem is fixed or not. If there is no response I'll assume the problem is fixed by commit 21ea077 and close this report after the next release.
Thanks in advance.
Hi, I compile it but the conference call isn't working... I added all the pidgin log, I will try to send you the log of the communicator application.
In the log I don't see any reliable way to recognize which ICE dialect to use to communicate with the conferencing server (perhaps it's hard-coded in Lync/OCS client corresponding to the server release?).
The best we can do for now is to retry the call with the other ICE version when the first attempt fails. Please check current git HEAD whether it helps.
@reporters: PING. Your missing feedback is blocking the next release.
Sorry for the delay. It didn't work... I will upload the pidgin log and the communicator log so you can check what is happening. I will try to do that today.
Ping? The logs are still missing.
Sorry for the delay. Tomorrow I will upload the communicator logs. Today I attached the Pidgin logs.
Pidgin log doesn't show any new information. Communicator logs would be more helpful in order to see how original client connects to a conference in this environment.
I tried to enable the logs of Communicator 2007 but I couldn't do that. The link in the Pidgin FAQ that should show us how to do it doesn't work.
Could you tellme how I can obtain the logs that you need?
Jakub: should the latest changes to git HEAD fix this bug?
If yes, then DemonCcC: please retest.
No, they're unrelated. The updates are for TCP transport support we're working on in libnice.
I am seeing the same problem with pidgin-sipe 1.18.1 (Fedora 19, pidgin-2.10.9-1.fc19).
Perhaps this is helpful:
Just curious: does that mean that in your installation you have automatic recording of all Lync Voice Calls? I.e. when I call you with Lync, there are two clients on your side: your client and the "compliance service" (my guess what this is) that makes a mandatory record of the call.
No, AFAIK there is no compliance service that records every call. At least I am not seeing it in the participants list.
Please try latest git HEAD; this change possibly fixes the issue.
