Delay (in one direction) introduced by IP gateways

In G711: Average delay of 100 ms for GD/GD2/GA/GA2/INTIP/INTIP2
Average delay of 71 ms for GD3/GA3/INTIP3
(60 ms for an IP Phone (e-Reflexes/ series 8))
In G729: Average delay of 120 ms for GD/GD2/GA/GA2/INTIP/INTIP2
Average delay of 72 ms for GD3/GA3/INTIP3
(70 ms for an IP Phone (e-Reflexes/ series 8))
In G723: Average delay of 150 ms for GD/GD2/GA/GA2/INTIP/INTIP2
Average delay of 95 ms for GD3/GA3/INTIP3
(90 ms for an IP Phone (e-Reflexes/ series 8))
In addition to the here above mentioned full NGP and full "GD/INTIP" configurations, the mixed case
between a GD3/GA3/INTIP3 board and a GD/GD2/GA/GA2/INTIP/INTIP2 board will introduce the
following one way average delay:
In G711
85 ms
Transit: approx. 20 ms (there is no transit in G711)
Note: All the figures given for the delay have been measured in a case without background noise
and IP disturbance.
