I have a few questions regarding CCM traces. I’ve read through my fair share of
trace files but I recently noticed something within CCM traces that doesn’t
quite make sense to me. Below is an excerpt of a CCM trace for an on-net call.
The calling device is SEP001C58A2B308 (DN 3500/Line1_RTP – IP 192.168.102.175)
and the called device is SEP001C58F075EA (DN 3037/Line1_RTP – IP 192.168.102.203).
I’ve omitted a large portion of the trace and only included relevant lines.
Questions listed below trace lines.<o:p></o:p></span></p>
