This is a multi-part blog series. This is Part 2.For other blog posts in this series please click the relevant links – Part 1, Part 2.
In my last blog post I introduced you to Lync Insights module and some of the CQM queries and file transfers cmdlets. In this post I will cover some powerful cmdlets which will provide you deep insight into the usage of Voice within your Lync environment.
I would highly recommend you to read Part1 of the article as that lists the pre-requisites required for these cmdlets to run.
All Lync to Lync Calls
Get-LsP2PLyncToLyncAudio is the cmdlet you need for this. This cmdlet will show you all the calls between Lync users and whole lot of other information like the Edge server used, time of the call, Disconnect time etc. 
All Lync/PSTN to/
from PSTN/Lync
Calls
Get-LsP2PPSTNAudioOnly will show all the calls in which PSTN connectivity was involved 
All Peer to Peer Lync Usage
Get-LsP2PSession will show you all the peer to peer sessions in your Lync environment- Audio, Video, desktop sharing, etc. You can then filter by whole lot of different properties to narrow down what you need. 
Get Top Called Number From Lync To PSTN
Get-LsTopCalledNumberFromLyncToPSTN will show you the most common numbers dialled to PSTN from Lync. Really useful to audit and detect any misuse. 
Get Top Called Number From PSTN To Lync
Get-LsTopCalledNumberFromPSTNToLync will show you the Lync users who receive the most number of calls from PSTN. 
Get Top Calling Number From Lync To PSTN
Get-LsTopCallingNumberFromLyncToPSTN will display the Lync users who makes the most number of outbound calls to PSTN 
Get Top Calling Number From PSTN To Lync
Get-LsTopCallingNumberFromPSTNToLync will display the PSTN users who make the most number of inbound calls to your Lync environment
Top Used Gateway
How do you quickly determine how many calls each of your Gateway is processing? Is you gateway being used to full capacity? Or is just doing nothing?
Get-LsTopUsedGateway will tell you all this information breaking down how many streams it handled
Top Used Mediation Server
How do you quickly determine how many calls each of your Meditation server is processing?
Get-LsTopUsedMediation will tell you all this information
Who is on the phone for longest?
Get-LsTopVoiceCallsByMinutes will show you how long each of the call lasted. 
Top voice users by calls
Get-LsTopVoiceUsersByCalls will show you how many calls each users have made/received. 
How many users dialin into dial in conferencing from PSTN
Well, there is no cmdlet which gives you exactly that information as this information is included in Get-LsP2PPSTNAudioOnly cmdlet. All you have to do is filter by you dial in conferencing number. Assuming your dialin conferencing number is +441234567890 you can do:
Get-LsP2PPSTNAudioOnly | where-object {$_.tophone –like “*+441234567890*’}
Usage Scenarios
Below are some of the usage scenarios I can think where the above cmdlets can be useful:
- Schedule alerts when a certain phone number is dialled. So if someone dials are premium rate number you are alerted.
- You can get alerted when calls exceed certain number of minutes from/to certain user
- Get alerted when one of your Gateway/Mediation server is handling very low number of calls compared to another.
- Report on your dial in conferencing usage
- Detect misuse of telephony environment e.g. if too many calls are made to certain numbers.
- Proactive fault finding. You can find the calls which are really short e.g <10 seconds.
- Call trending over period of time to understand voice usage.

The key aim of this blog post was to demonstrate cmdlets using which you can gather information on voice usage within your environment. The next blog posts will show how you can gather some really useful information on Conferencing usage, client login statistics like location and time, Client logging history and lot more.
Enjoy!
