Lync with Cisco VCS Integration/HD Integration

Most of the organisation wil be having High defnition conference feature available.So the users who are using Lync they can utilise that feature using Lync client easily with below steps.The document is svailable on Cisco sites but still below one will be an easy refernce for you.

First you need to add VCS domain as truted application in Lync topology then only Lync will accept request from VCS.

Here is command to make VCS as trusted application:
1- Add application pool
New-CsTrustedApplicationPool -Identity <vcsdomainfqdn> -Registrar LyncFEPool -site <Sitenumber you want to integrate> -RequiresReplication $false -ThrottleAsServer $true -TreatAsAuthenticated $true

2- Add application
New-CsTrustedApplication -ApplicationID VCSApplication1 -TrustedApplicationPoolFqdn <vcsdomainfqdn> -Port 5061
3- Set The encryption Level.
set-CsMediaConfiguration -EncryptionLevel supportencryption
4- Create static route to route the request towards VCS.
$Route1=New-CsStaticRoute -TLSRoute -Destination "vcsdomainfqdn" -MatchUri "domainname" –Port 5061 -UseDefaultCertificate $true
Set-CsStaticRoutingConfiguration -Identity global -Route @{Add=$Route1}

Above part is from Lync side.Same way need to configure Cisco VCS to accept lync request.
Once both side configured you can dial conference number from Lync and enjoy the conference from your Desk.
 

Port Requirements for Lync 2010 Application sharing with external user

For Small buisness network this topic may not be that much usefull,but for a Large enterprise with restricted network setup this will be very usefull.Below requirements i captured using lot of testing and network tracing.When i recieved this requirement there was no articles clearly mentioned about how we can achieve this,all was mentioned some specific ports for application wise.

Scenario:Users are sitting in a restricted network.User only have text IM access with othere users as well as federation/external users.Requirement here is to application sharing with external/federated users.After the study i concluded with below ports for application sharing with external users.

Public to edgeserver:

TCP/443

UDP/3478

TCP/8057

TCP/50,000-59,999 (Outbound only)

From the internal Client to the internal Edge:

TCP - 443
UDP – 3478

Above ports for only to conference and Media traffic from internal user to External user.

If you wanted to have internal conference between 2 restricted netwok users below is the port requirements.

Client to Front End Pool

UDP		49152 to 57500
TCP		8057
TCP		443
TCP		49152 to 65535
TCP		448

Client to AV Pool

UDP		49152 to 57500
UDP		57501 to 65535

 

Set Media Port Ranges in Lync

Here i am explaining this mainly for Enabing QoS for Lync services.If your organization is with large network this is necessary to limit lync Media traffic into a defined port ranges.SO this QoS can be enabled inall network appliances and assign the bandwidth from the network level.
Below is the commands to set the mediaports in Lync 2010

Client Ranges

Set-CsConferencingConfiguration -ClientMediaPortRangeEnabled 1 Set-CsConferencingConfiguration -ClientAudioPort 20000 -ClientAudioPortRange 40 -ClientVideoPort 20040 -ClientVideoPortRange 40 -ClientAppSharingPort 20080 -ClientAppSharingPortRange 40 -ClientFileTransferPort 20120 -ClientFileTransferPortRange 40 -ClientMediaPort 20160 -ClientMediaPortRange 40

Lync Pools

Set-CsConferenceServer -Identity <PoolFQDN> -AppSharingPortStart 40803 -AppSharingPortCount 8348

Set-CsApplicationServer -Identity <PoolFQDN> -AppSharingPortStart 40803 -AppSharingPortCount 8348

 

 

Force to use Lync Web App for conferences

If you have lync 2010 instaled on your system ,when you click on join conference URL it will launch your Lync 2010 client.What will happen some other organisation send you the link to join conference?you will not be able to join the meeting.
If you dont have Lync 2010 in your system you wil get below screen

 

So this will give you the option to join the meeting.But for such above case it is difficult because Lync default behaviour is like that.So if you want to force the use of Lync web app follow the below steps

simply add ?sl= to the meeting URL

Eg:https://meet.sipdomain.com/test/abcdefg34?sl=

The Lync Client will not launch and you can choose to run Lync Web App
