I did an OPS-DIR review of draft-ietf-siprec-protocol-16.

This document describes a mechanism for recording SIP 
sessions, ostensibly, only with the knowledge of the SIP endpoints.

The document is clear and mature (which I would hope was
the case for a -16 working group ID).  In particular, the security 
considerations section seems quite well written to me.

I find no additional operational concerns beyond those 
present in running any secure SIP infrastructure.

I do observe that the stage upon which this standards
track ID is dancing on is rather close to the forbidden 
zone as described by RFC 2804. But the stage was 
selected when the working group was formed and it
 is too late to revisit if that was a stage that an IETF 
working group should be dancing on.
