0x0101 RTP Payload Size (VDAC-ONE)

By changing the multiple of the payload size, you can configure how much encoded PCM data a packet contains.

Example: For G.711, a 160-byte payload of encoded PCM data is sent at the G.711 Basic Packet Rate of every 20 milliseconds. But if you change the multiple for G.711 to 2x, then a 320-byte payload is sent every 40 milliseconds.

In effect, changing the multiple also changes the throughput available over an Ethernet network. Larger packets create greater network delay overall, but they use the Ethernet bandwidth more efficiently. Smaller packets may use the Ethernet bandwidth less efficiently, but they may provide better voice quality.
