Operating Parameters
LBRCodec
Description
This parameter allows you to specifiy which low-bit-rate codecs are available. The Cisco ATA is capable
of supporting two G.723.1 connections or one G.729 connection. When G.723.1 is selected as the low-bit-rate
codec, each FXS port is allocated with one G.723.1 connection. When G.729 is selected, only one FXS port
is capable of operating with the G.729 codec. The allocation of the G.729 resource to the FXS port is dynamic.
The G.729 resource, if available, is allocated to an FXS port when a call is initiated or received; the resource
is released when a call is completed.
The following values are valid:
• 0—Select G.723.1 as the low-bit-rate codec.
• 3—Select either G.729 as the low-bit-rate codec.
