Software Features
When operating with a low-bit-rate codec, the Cisco ATA can support either two G.723.1 connections or
one G.729 connection. The selection of G.723.1 or G.729 must be statically configured. When G.723.1
is the low-bit-rate codec, each FXS port is allocated with one G.723.1 connection. When G.729 is used,
only one FXS port can use G.729. For more information, see the
"ConnectMode" section on page
