802.1p Support On The Network Interface Card (NIC)

Please note: this is legacy documentation. Please check out https://docs.miarec.com/all/ for the most up-to-date documentation and user guides. 


This article described how to enable 802.1p tagging support on Ethernet Network Interface Card (NIC) adapter. 802.1p is is a standard that enables Quality of Service (QoS). QoS gives higher priority to VoIP audio packets, thus improving call quality (less delays, less packet loss).

When 802.1p support is disabled on a computer, where MiaRec is running, then the following issue may occur:

  • one-way audio (when only one side of the conversation is recorded)
  • no audio is recorded at all (both sides of the conversation are not recorded).

When one of the above issues occurs, it is necessary to check if NIC supports 802.1p.

Open properties of your NIC.

And then click on the "Configure" button.


Check if you have there option "802.1p Support" and make sure it is "Enabled".

Note, if you do not have such an option, then do nothing (your NIC supports 802.1p by default).


If a problem with audio still exists, please, contact our technical support team.
