[Freeswitch-users] Explanation of rtp_audio_in / out fields in XML CDR's?

[Michael Collins]

Mick,

This data is definitely not on the wiki - or anywhere else that I can see.
I think we can crowdsource this to get the info collected and then add it
to the mod_xml_curl wiki page <http://wiki.freeswitch.org/wiki/Mod_xml_cdr>.
For the record, here's a quick dump of the fields that I took from an XML
CDR:

    <rtp_audio_in_raw_bytes>10664</rtp_audio_in_raw_bytes>
    <rtp_audio_in_media_bytes>8772</rtp_audio_in_media_bytes>
    <rtp_audio_in_packet_count>62</rtp_audio_in_packet_count>
    <rtp_audio_in_media_packet_count>51</rtp_audio_in_media_packet_count>
    <rtp_audio_in_skip_packet_count>18</rtp_audio_in_skip_packet_count>
    <rtp_audio_in_jb_packet_count>0</rtp_audio_in_jb_packet_count>
    <rtp_audio_in_dtmf_packet_count>0</rtp_audio_in_dtmf_packet_count>
    <rtp_audio_in_cng_packet_count>0</rtp_audio_in_cng_packet_count>
    <rtp_audio_in_flush_packet_count>11</rtp_audio_in_flush_packet_count>
    <rtp_audio_in_largest_jb_size>0</rtp_audio_in_largest_jb_size>
    <rtp_audio_out_raw_bytes>11524</rtp_audio_out_raw_bytes>
    <rtp_audio_out_media_bytes>11524</rtp_audio_out_media_bytes>
    <rtp_audio_out_packet_count>67</rtp_audio_out_packet_count>
    <rtp_audio_out_media_packet_count>67</rtp_audio_out_media_packet_count>
    <rtp_audio_out_skip_packet_count>0</rtp_audio_out_skip_packet_count>
    <rtp_audio_out_dtmf_packet_count>0</rtp_audio_out_dtmf_packet_count>
    <rtp_audio_out_cng_packet_count>0</rtp_audio_out_cng_packet_count>

I think raw_bytes, media_bytes, packet_count, and media_packet_count are
self-explanatory. I think cng_packet_count is probably self-explanatory
too. My question on dtmf_packet_count would be whether it's only for
RFC2833 packets (I suspect yes, but would like confirmation).

If anyone knows these please reply to this email and Mick and I will get
them documented on the wiki (right Mick? ;)

rtp_audio_in_skip_packet_count
rtp_audio_out_skip_packet_count
rtp_audio_in_jb_packet_count
rtp_audio_in_flush_packet_count
rtp_audio_in_largest_jb_size

Thanks all!
