Local Tone Playout Reporting
Local Tone Playout Reporting
Local tones are tones that the Cisco ATA plays to its FXS port. Each of these tones corresponds to an
identifier, and these tone type identifiers are placed into the prserv debug log. These identifiers supply
information that administrators can use to help analyze call flows for debugging purposes.
Local tones are different from other tones because local tones are not carried within the inband audio.
Instead, the Cisco
ATA is prompted by a network event to play the tone, and the Cisco ATA g e nerates
the tone for the exclusive purpose of playing it to the attached telephone handset. For example, during
a call between the Cisco
ATA and a far-end phone, the far-end user might press a digit on the dial pad,
thus sending an AVT Named Signaling Event to the Cisco
ATA. This event prompts the Cisco ATA t o
generate a DTMF tone and to play the tone locally to the Cisco
ATA phone.
Table 8-1 lists the tone type identifier and its description for local tone reporting.
