Media Quality Summary Report - filters

I am looking at this summary report and playing with applying the filters. There are no calls identified as VPN calls. Does the data here rely on the clients using Microsoft VPN, or is there a way to get other product VPN's recognized?
Tom

Hi,Tom,
Per my knowledge it does not only identify MS VPN sessions,I doubt that you didn't include VPN subnet in your QoE Monitoring server,here are some information about
QoE monitoring server protocal specification the and the Lync QoE discovery knowledge for your reference.

Lync Monitoring - Media Quality Diagnostics Reports are empty?

Hi all
We have a working Lync Monitoring solution, which I've used for various troubleshooting. However now for the first time I wanted to view some media quality data and there doesn't seem to be any? I can view the user activity reports and everything just fine,
but any report related to QoE seems to have no data. We have enabled purging and gathering of QoE data and the retention period is 60 days.
I don't know where to go from here. Any ideas? I was thinking about looking in the sql database to see if there is any data, but unfortunately I'm unsure which database to check and what query command i should use on which table.
Thanks for any help you can provide.

Hello Casper
my first point of reference would be to take a look into the QOE database to see if there is any information of interest in their.
Also it might be work checking that the backend services are running for the instance to which the QOE database is associated with.

How to improve the video quality send by lync 2013?

we have one sip client make call with lync 2013 client, and each other support MS rtv video capabilities, after the sip session begin, then video rtp packet send on each directory, all the time our client send 720p video codec to lync 2013 client
, but we only receive the lower format video codec from lync 2013 , and the video format is changed all the time ,some times is 720p then 960*544, then 960*720, or 630*360,,etc. we wonder how can lync client send stable 720p video codec, and we have acheive
the funtion accord ms-rtp.pdf document, and our client can calculate bandwidth using rtcp step accord ms-rtcp , then we should do what else in order to get stable 720p from lync 2013...thank you.

thank you
now we realy have enoght network bandwidth, is heigher to 4-6Mbps, so I think which is in one right work enviroment.
Now I notice that the video format received from lync 2013 at the begining of the call is 720p, and some times change to 960*720, or 960*544, but for many time it may be change between these three formats, but in some times the video format would
change to 640*360, once which change to this mode then it would keep in this sitiunation for long long time, and would never chanege to the heigher ones so it is one incredible things.
how could we change this sitiuation to get one good video format for heigher video effect.

Nortel CS 1000 v7.5 with Lync 2013 using AudioCodes Mediant 1000 E-SBC

Hi,
I am trying to setup CS 1K to Mediant 1000 E-SBC using SIP trunks. The Mediant will connect to Lync 2013 again using SIP.
I am trying to add Mediant 1000 as a static SIP end point in NRS. Does anyone know of any specific setting that needs to be configured on both NRS as well as Mediant 1000 for it to be registered as an end point.
Also when I try to register the Mediant, SIP 403 forbidden error appears in the syslog of Mediant.
Any inputs will be much appreciated...

Lync 2013 Call Quality Reporting Time Intervals

Does anyone know the time interval used to report the metrics associated with the Lync 2013 call quality reports? If so, is there documentation that confirms that?
For example, Max Packet Loss Rate gives you a percentage. However, I haven't found any documentation that says how long a sample period is. Was that Max Packet Loss rate experienced for, at least, 1 second, 5 seconds, 30 seconds, 1 mintue etc?
I haven't found any conclusive information regarding how long of a period they may have experienced that max packet loss number, nor at what point during the call.
Thanks in advance for the help!

Lync 2013 and Audiocodes ESBC Mediant 1000 - poor audio quality

Bit of an odd issue that I've been looking into for the past few weeks - our part of our change from a pilot Lync install to production we have had an Audiocodes ESBC Mediant 1000 installed to serve as a Media Gateway between the Lync Mediation Server and
our Gamma Telecom provided SIP trunk.
However under certain situations my users are reporting exceptionally poor audio quality with the Lync server reporting website reporting a very high packet loss and our ESBC reporting a high 'Average voice delay' (often greater than 80ms).
I have established that by taking these steps the issue can be replicated with almost impunity-
Make incoming call from mobile phone (or landline) - pickup call on Lync Deskphone (CX300/CX500/CX600 and VVX410 all have the same).
Begin a consultative call transfer with an external (another mobile/landline) or internal number which places the incoming call on hold.
Complete the call transfer - at this point the audio quality is still as expected.
Begin a new call from a Lync phone to an external number - at this point the audio quality for the phone call that has been transferred and the new call instantly degrades.
My basic topology is-
Fibre Leased Line - Cat5e cable - Router - Cat5e cable - DMZ Switch - Cat5e cable - Audiocodes Mediant 1000 - Cat5e cable - Servers VLAN - Switch - Fibre - Core switch (layer 3) - Fibre - VMWare Host (ESXI v5) - Lync Server (VMNET 3 adapter)
I have been able to replicate the issue when using both TCP and TLS between the Lync Mediation Server and the Audiocodes gateway.
Over the next day or so I will be looking to get the SIP trunk connected directly to the Lync server to see if that makes any difference (ruling out the Mediant 1000 as a possible cause) but in the meantime does anyone have any ideas as to what could be
causing this most weird situation?

Hi,
Please disassociate the Edge Server from the Mediation and check the delay again.
Please check port 3478 to the internal interface of the Edge Server from all internal clients (including the Mediation Server).

Lync 2013 Monitoring Server - Database reporting

Hi there,
Im a business intelligence professional rather than a Lync professional so excuse me if my question may show niavete or a clear lack of experience, both would probably be correct.
The basic question is, how does Lync record the relationship between a call being received and the call that is transferred.
Effectively I am looking to see how the monitoring server applies a unique record to a call. This looks like the SessionIdTime field. I also deduce that the 'ReplacesDialogueId' field is used to record when a call effectively replaces another one, and I
have formed a self join on the SessionDetailsView to track a calls progress.
Im struggling though when this relationship is not there. So for example, when a call comes in and is answered by a receptionist, we have the initial call entering the queue, with the call being answered by Reception having a replacedialogId that replaces
the call coming into the queue. Lets say that the receptionist then calls a director to see if they are available, and then transfers the call. There is a relationship between the call being made to the director, and the caller speaking to the director with
the dialogId and replacedialogid fields, though there is no relationship between the receptionist taking the call, and the receptionist calling the director and putting the call through.
Again, please forgive my noobie questions. In summary, how does Lync record the relationship between a call being received and a transferred call.

They are sparse, many of us have written custom reports but I forget what I've done as soon as I've done it. The Lync 2013 CDR Database Schema is available here:
http://technet.microsoft.com/en-us/library/gg398570.aspx
Typically what I do is just dig in and make test case calls, export the query results to something easy to work with like Excel and reverse engineer what I need for my reports. Watch the CorrelationID and anything else you can line up.
I'm not aware of any great guides that walk you though this unfortunately.

Hi All,
I have utilized the DQS for my organization Data Cleansing project. And we have built Data Quality reports using DQ output.
We also use Profiler Summary report in the Activity Monitor, but this is manual process where Data owners need to manually enter into the Activity monitor and generet the porofiler report.
My question is, which DQS table store the this Profiler summary report where by I can automate the report through that source.
Here is the screenshot of the report we are looking at, we need to find out which DQS source table got this information.
Thanks for the help

Lync 2013, Diagnostic Report ID: 52161, What does it mean?

I am digging one report and found ID 52161, reason="Session was terminated as we are tearing down the conference due to failure on a different session". Can anyone explain it in more details? how it happens?
also does anyone know where I can found a list of all Lync diagnostic IDs explanations?

I am seeing this for some (many, but not all) Lync 2013 users when they try to use the "Call me at" feature for a meeting join. The other line/audio device joins the conference but the client that instructed it to do so drops off with that error
after 30 seconds.
The client sends a SIP 200 and then 30 seconds later it sends a BYE. We've tested with multiple platforms and it seems to be related to the user doing the inviting, not the IP or software.

Unable to configure monitor & report in Lync 2013

We have SQL Server 2012 in our environment. I want to enable monitor report in Lync 2013. i have separate Lync sql instance.
I am trying to configure new database in Reporting Service Configuration manager in report Server database Configuration wizard.
while testing connection getting below error.
could not connect to server:A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to
allow remote connections.(provider:Named Pipes provider,error:40-could not open a connection to SQL Server)
kindly help to resolve issue.

In my opinion, if you have problem with your firewall, try disabling it and connect. If it doesn't work, means it could be your SQL configuration / enabling of TCP/IP problem.
Check the below blog:

If you are able to connect to SQL Server by physically logging on to the server, but unable to connect from a client computer then execute the below to check the SPN.
-- run this command to see if SPN is not found
EXEC xp_readerrorlog 0,1,"could not register the Service Principal Name",Null
If the SPN is not found setup and register an SPN. (https://msdn.microsoft.com/en-us/library/ms191153(v=sql.110).aspx#Manual)

Lync 2013 custom SSRS reports from CDR

Trying to replicate canned Lync 2013 User Activity Report, but with more filtering capability, using SSRS. Necessary to do this way because we're adding details like user names, departments and locations from our Active directory.
Have been unable to ever find support on WHAT the query or stored proc IS behind the UA report. If I have that code I can incorporate that with our data.
Any help appreciated!
Jim Nelson
James Nelson

The CDR schema can be found here, which will be helpful for creating your reports:
http://technet.microsoft.com/en-us/library/gg398570.aspx
Most queries start from the SessionDetails Table:
http://technet.microsoft.com/en-us/library/gg398589.aspx
For hacking up existing SSRS reports to see what procedure or view they call, you'll have better luck asking in the SQL forums.

Lync 2013 commands shell to get the report which user is connecting to which pool in coexistence with Legacy version

HI,
We have LYNC 2013 in coexistence with OCS 2007 R2 and setup is like that user can connect to any pool either sip is exist on OCS 2007 or on LYNC 2013
Do we have any command shell to get the details about which user is connecting to which pool?
lync 2013 commands to get the report which user is connecting to legacy pool in coexistence with ocs 2007
Thanks
jitender

HI Holger,
Thanks for reply!!
But the above link will not work as per scenrio.
The SIP addresses has been migrated to LYNC server. ther is no user host on OCS server. However in communicator client the manual entry is done and OCS pool name is given. OCS pool just redirect the query to LYNC pool.
And we need to idenfy the SIP user request on OCS which are redirecting by ocs pool to lync pool
In other word we can say this question like: How to collect the number of SIP users connections coming on OCS Direct server?
Thanks
jitender
As all users are migrated to Lync Server, all users will be redirected to their home pool.
You want to collect the number of SIP connections coming from OCS server that means you want to count the number of Lync client with manual configuration pointing to OCS server.
This information is stored in SIP session. There is no Lync command to get this kind of information natively.

Call Reliability Alerts
Database queries for Call Detail Records (CDR). These records are written by Front End Servers to reflect whether end users were able to connect to a call or why a call was terminated. These queries result in alerts that indicate when a wide range of end
users are experiencing connectivity issues for peer-to-peer calls or basic conferencing functionality.
Media Quality Alerts
Database queries that look at Quality of Experience (QoE) reports published by clients at the end of each call. These queries result in alerts that pinpoint scenarios where users are likely to be experiencing poor media quality during calls and conferences.
The data is built upon key metrics such as packet latency and loss, metrics that are known to directly contribute to call quality.
Component Health
Individual server components raise alerts by using event logs and performance counters. These alerts indicate failure conditions that can severely impact one or more end user scenarios. These alerts can also indicate a variety of other failure conditions,
including services not running, high failure rates, high message latency, or connectivity issues.
Dependency Health
Failures can occur for a variety of external reasons. The management packs now monitor and collect data for some of the critical external dependencies that might indicate severe issues, including IIS availability, CPU and memory usage of servers and processes,
and disk metrics.

Lync 2013 Cloud Service Limitations

Can anyone point me to some references on the limitations with Lync 2013 in the
cloud? What are some pros and cons about cloud services with voice and video?

How much of this list is still true to the limitations of Lync Online?
The features not available are:
