To call the Phone 2 port on Cisco ATA Y, you would dial 5558888**192*168*2*112#. Related Configuration Parameters • IPDialPlan, page 5-60 • DialPlan, page 5-52 Setting the Audio Codecs You can configure the following codec-related settings: • Low-bit-rate codec-When operating with a low-bit-rate codec, the Cisco ATA can support either two G.723.1 connections or one G.729 connection. You must statically configure the selection of G.723.1 or G.729 by using the LBRCodec parameter. When G.723.1 is the low-bit-rate codec, each FXS port is allocated one G.723.1 connection. When G.729 is used, only one FXS port can use G.729. The G.729 resource is allocated in a dynamic manner. When a call begins, the FXS port requests and takes an available G.729 resource. The Cisco ATA releases this resource when the call is completed. Use Bit 1 of the AudioMode parameter to disable and enable the use of the low-bit-rate codec. Related Configuration Parameters - LBRCodec, page 5-23 - AudioMode, page 5-24 • Voice codec-You can configure the preferred voice codec for transmitting and receiving voice data by using the TxCodec and RxCodec parameters, respectively. Cisco recommends that you configure the same voice codec for TxCodec and RxCodec.

Setting the Audio Codecs
You can configure the following codec-related settings:
Low-bit-rate codec—When operating with a low-bit-rate codec, the Cisco ATA can support either
two G.723.1 connections or one G.729 connection. You must statically configure the selection of
G.723.1 or G.729 by using the LBRCodec parameter.
When G.723.1 is the low-bit-rate codec, each FXS port is allocated one G.723.1 connection. When
G.729 is used, only one FXS port can use G.729. The G.729 resource is allocated in a dynamic
manner. When a call begins, the FXS port requests and takes an available G.729 resource. The
Cisco ATA releases this resource when the call is completed.
Use Bit 1 of the AudioMode parameter to disable and enable the use of the low-bit-rate codec.

Voice codec—You can configure the preferred voice codec for transmitting and receiving voice data
by using the TxCodec and RxCodec parameters, respectively. Cisco recommends that you configure
the same voice codec for TxCodec and RxCodec.
Related Configuration Parameters

Silence suppression—You can configure silence suppression for G.711/G.723.1/G.729 by using the
ConnectMode parameter (Bit 0 for the
Phone 1
port and Bit 16 for the
Phone 2
port).
