Description
Use the drop-down list to select the preferred codec
for the system's VoIP configuration, either G.723.1
or G.729.
Note: AltiWare always uses the same code on both
transmit and receive directions. If a third
party H.323 device is used which supports
both G.732.1 and G.729, this device's
preferred codec setting must be configured to
use the same as AltiServ's.
