Chapter 9 Troubleshooting Local Tone Playout Reporting • The tag value is 16, which corresponds to RTP statistics messages. This is derived from Table 5-9 on page 5-62. • The ch (active line of the Cisco ATA) is line 0, which is the Phone 1 port of the Cisco ATA. • The transmission statistics include the duration, packet count and byte count. The receiving statistics include the duration, packet count, byte count, last packet count, lost packet count and average jitter. 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 generates 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 to generate a DTMF tone and to play the tone locally to the Cisco ATA phone. Table 9-1 lists the tone type identifier and its description for local tone reporting.
