Howto:Set Type of Service (ToS) DiffServ DSCP Values for innovaphone Windows Applications

2021-06-15T15:02:42Z

Zandweter: /* Problem Details */ End port should be bigger then Start port error

==Applies To==
This information applies to all innovaphone Windows Applications sending the RTP Data (this is currently the SoftwarePhone (audio), myPBX launcher (video) and myApps (audio, video))

==More Information==

===Problem Details===

In contrast to the innovaphone devices, that allows you to [[Reference9:IP4/General/Settings|specify the IP v4 TOS header field value]] used for voice and signalling IP packets, the MS Windows based applications like SoftwarePhone, myPBX or myApps do not have any possibility to set ToS Values on the RTP packets due to restriction of the Microsoft Windows operating system.

Instead to set the ToS Value in the Application the [http://technet.microsoft.com/en-us/library/dd919203%28WS.10%29.aspx Policy-based Quality of Service (QoS)] provided by the MS Windows operating system can be used to mark the IP packets.

Usually the configuration of the Policy-based Quality of Service is done by defining a [http://technet.microsoft.com/en-us/library/hh831689.aspx Group Policy Object (GPO) in the Group Policy Management Console (GPMC)]. This could be done for a single computer or distributed to a number of computers via the domain controller.

The DSCP Values in the above example are default DSCP values used by innovaphone devices, according to the Wiki article [[Howto:Calculate Values for Type of Service %28ToS%29 from DiffServ or DSCP Values]]. You may change this values to meet requirements on your traffic prioritisation and routing equipment.

In the Windows 8, Server 2012, Windows 10 and later it is possible to use [http://technet.microsoft.com/en-us/scriptcenter/powershell.aspx PowerShell] to configure the values with the [https://technet.microsoft.com/en-us/library/hh967471(v=wps.630).aspx NetQosPolicy] Cmdlet.

The above table can be added to the Group Policies by the following powershell commands (administrator account access right required):

<code>
New-NetQosPolicy -Name "innovaphone myPBX Video RTP" -DSCPAction 34 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\myPBX\myPBX.exe" -IPProtocolMatchCondition UDP -IPSrcPortStartMatchCondition 50000 -IPSrcPortEndMatchCondition 50100
New-NetQosPolicy -Name "innovaphone myApps Video RTP" -DSCPAction 34 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\myApps\myApps.exe" -IPProtocolMatchCondition UDP -IPSrcPortStartMatchCondition 50100 -IPSrcPortEndMatchCondition 50199

New-NetQosPolicy -Name "innovaphone SoftwarePhone Audio RTP" -DSCPAction 46 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\SoftwarePhone\softwarephone.exe" -IPProtocolMatchCondition UDP -IPSrcPortStartMatchCondition 2050 -IPSrcPortEndMatchCondition 16000

New-NetQosPolicy -Name "innovaphone SoftwarePhone Signalling H225" -DSCPAction 26 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\SoftwarePhone\softwarephone.exe" -IPProtocolMatchCondition TCP -IPSrcPortStartMatchCondition 2048 -IPSrcPortEndMatchCondition 59999
New-NetQosPolicy -Name "innovaphone SoftwarePhone Signalling H323 TCP" -DSCPAction 26 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\SoftwarePhone\softwarephone.exe" -IPProtocolMatchCondition TCP -IPDstPortMatchCondition 1720
New-NetQosPolicy -Name "innovaphone SoftwarePhone Signalling H323 TLS" -DSCPAction 26 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\SoftwarePhone\softwarephone.exe" -IPProtocolMatchCondition TCP -IPDstPortMatchCondition 1300
New-NetQosPolicy -Name "innovaphone SoftwarePhone Signalling SIP" -DSCPAction 26 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\SoftwarePhone\softwarephone.exe" -IPProtocolMatchCondition Both -IPDstPortMatchCondition 5060
New-NetQosPolicy -Name "innovaphone SoftwarePhone Signalling SIPS" -DSCPAction 26 -NetworkProfile All -AppPathNameMatchCondition "%programfiles(x86)%\innovaphone\SoftwarePhone\softwarephone.exe" -IPProtocolMatchCondition TCP -IPDstPortMatchCondition 5061
</code>

Please note, the QoS policies added via powershell NetQosPolicy cmdlet are not visible in the Group Policies Editor (gpedit.msc). To list the configured QoS policies use <code>Get-NetQosPolicy</code> cmdlet.

The GPO on the PCs will refresh from time to time automatically. To apply the changes to the GPO immediately following command can be used:
Gpupdate.exe /force

===Known Problems===
In some cases setting of the following registry key is required to ensure the DSCP values are applied:

HKEY_LOCAL_MACHINE /SYSTEM / CurrentControlSet / Tcpip / "Do not use NLA" = 1

Reboot of the PC is required afterwards.
