The last field in the VoIP packet structure is the payload field which carries the encoded voice data. The number of bytes constituting the entire packet comes from the pre-defined packet size. Typically VoIP packets are 10ms, 20ms or 40ms packets (where the size in milliseconds corresponds to the payload only).

Each audio frame is a data record that contains the samples for all of the channels available in an audio signal. The size of an audio frame is calculated by multiplying the sample size in bytes by the number of channels, so a single frame of stereo 16-bit audio is 4 bytes long and a single frame of 5.1 floating-point audio is 24 (4 bytes per ...

Opus provides a very performant 26.5 ms latency using its default settings (20 ms frame size), making it highly suitable for Voice over IP (VoIP) communications. Narrowband to Fullband One unique feature of Opus is that it works for both sampling human voices and music.
What is Frame Size? - JamKazam

I assume this is because it is audio in and audio out (the frame size number is for one way, so it must get doubled for a round trip). Here are a few examples: 1) If you were on the default setting of 2.5ms and change to 2.0ms the difference is 0.5ms. 0.5 x 2 = 1.0. So you should see you interface latency decrease by 1ms.
