[Freeswitch-users] Monitoring audio quality

[Michael Lutz]

Hi Guys,

I have a prety large system with a lot of traffic. Sometimes I get
complains from customers about 'loud noises', 'not hearing audio', or
just 'bad quality audio'.
I can see a lot of info on the CDR's, no I have tried to search the
wiki and groups for some explanaition about how to interpret them, but
there is not much to find..

Is there someone who can tell me what these mean, and how to interpret
them, could they help me in finding issues with audio?

    <rtp_audio_in_raw_bytes>573964</rtp_audio_in_raw_bytes>
    <rtp_audio_in_media_bytes>572932</rtp_audio_in_media_bytes>

    <rtp_audio_rtcp_packet_count>0</rtp_audio_rtcp_packet_count>
    <rtp_audio_rtcp_octet_count>0</rtp_audio_rtcp_octet_count>

Or are there other (better) methods of finding problems related to bad audio?
