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
<a href="http://wiki.freeswitch.org/wiki/Mod_xml_cdr" target="_blank">mod_xml_curl wiki page</a>. For the record, here's a quick dump of the fields that I took from an XML CDR:<br>
<br>
<rtp_audio_in_raw_bytes>10664</rtp_audio_in_raw_bytes><br>
<rtp_audio_in_media_bytes>8772</rtp_audio_in_media_bytes><br>
<rtp_audio_in_packet_count>62</rtp_audio_in_packet_count><br>
<rtp_audio_in_media_packet_count>51</rtp_audio_in_media_packet_count><br>
<rtp_audio_in_skip_packet_count>18</rtp_audio_in_skip_packet_count><br>
<rtp_audio_in_jb_packet_count>0</rtp_audio_in_jb_packet_count><br>
<rtp_audio_in_dtmf_packet_count>0</rtp_audio_in_dtmf_packet_count><br>
<rtp_audio_in_cng_packet_count>0</rtp_audio_in_cng_packet_count><br>
<rtp_audio_in_flush_packet_count>11</rtp_audio_in_flush_packet_count><br>
<rtp_audio_in_largest_jb_size>0</rtp_audio_in_largest_jb_size><br>
<rtp_audio_out_raw_bytes>11524</rtp_audio_out_raw_bytes><br>
<rtp_audio_out_media_bytes>11524</rtp_audio_out_media_bytes><br>
<rtp_audio_out_packet_count>67</rtp_audio_out_packet_count><br>
<rtp_audio_out_media_packet_count>67</rtp_audio_out_media_packet_count><br>
<rtp_audio_out_skip_packet_count>0</rtp_audio_out_skip_packet_count><br>
<rtp_audio_out_dtmf_packet_count>0</rtp_audio_out_dtmf_packet_count><br>
<rtp_audio_out_cng_packet_count>0</rtp_audio_out_cng_packet_count><br>
<br>
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). <br>
<br>
If anyone knows these please reply to this email and Mick and I will get them documented on the wiki (right Mick? ;)<br>
