Reply To: Ethernet overhead on VoIP


There is, but the free calculators on this site don’t take it into account. Remember that Ethernet is a layer 2 (datalink) protocol, whereas IP/UDP/RTP are layer 3 and above.

We have a product called VoIP Select which also takes into account layer 2 overheads for Ethernet, Frame Relay, PPP and ATM.
