SIPTrmReason
SIP call termination reason (BYE, CANCEL, or SIP error codes, e.g., 404)
SipTermDesc
Description of SIP termination reason:
SIP Reason header, if exists, for example: SIP ;cause=200 ;text="Call
completed elsewhere".
If no SIP Reason header exists, the description is taken from the
reason text, if exists, of the SIP response code, for example: "417
Unknown Resource-Priority".
If no reason text exists in the SIP response code, the description is
taken from an internal SIP response mapping mechanism. For
example, if the device receives a SIP response "422", it sends in the
CDR "422 Session Interval Too Small method" as the description.
PstnTermReason
Q.850 protocol termination reason (0-127).
LatchedRtpIp

on to as a result of the RTP latching mechanism for NAT traversal.
LatchedRtpPort
