Software Features

This section contains topics that cover the protocols and services that the Cisco ATA supports:

•

SCCP Version

The Cisco ATA supports the Skinny Client Control Protocol (SCCP) Rev. 3.0 and 3.1.

Voice Codecs Supported

The Cisco ATA supports the following voice codecs (check your other network devices for the codecs

they support):

•

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

OL-4652-01

If the function button blinks slowly, the Cisco ATA cannot find the DHCP server. Check your

Ethernet connections and make sure the DHCP server is available.

Pressing the function button allows you to access to the voice configuration menu. For additional

information about the voice configuration menu, see the
