VoIP Per Call Bandwidth

The following calculation table explains the default voice payload sizes in CUCM or H.323 gateways. For additional calculations with customized values goto: TAC Voice Bandwidth Codec Calculator



Bandwidth MP or FRF.12 (Kbps) = Frame Relay
Bandwidth w/cRTP MP or FRF.12 (Kbps) = Frame Relay with compression
Bandwidth Ethernet (Kbps) = Ethernet

A standard G.729 call uses 26.8 Kbps of bandwidth for a call on Frame Relay.
A standard G.711 call uses 82.8 Kbps of bandwidth for a call on Frame Relay.
