Below are my comments (I appologise that they are a few days late). Most are editorial, but there are also a few questions.

Section      Comment

3                "CC indicator: a iniction" -> "CC indicator: an indication"
3                CC queue, is definition correct? Sounds like all failed calls.
4.1             "or be provided by a centralized application server" seems to suggest one (for both agent and monitor). Wouldn't "or be provided by centralized application servers" be more general?
4.1             Usage of the word "agent" is more general than in the definition where it is caller's agent. Example (3rd para): "Though it is expected that a UA that "implements call completion" will have both types of agents..."
4.1             Last para: I think the words "that have been" shall be removed from the following sentence " The monitor maintains information about the set of INVITEs that have been received by the UA(s) 
                  that may not have been considered successful by the calling user." otherwise I think the "considered succesful" refers to the UAs, not the INVITEs.
5                3rd para: "the the monitor"->"the monitor"
5                Para describing algorithm: Although there is no normative text, it suggests a FIFO queue since it is the entry that "has resided in the queue the longest" that is selected. Is this not a subject of local policy? Para 7.3 also describes this as a policy.
5                3rd para from the end: "an CC INVITE"->"a CC INVITE"
7.2             2nd para first sentence: "The callee's monitor(s) that receive the SUBSCRIBE establish subscriptions." Something is missing. to establish??
7.2             Last para. What do the underscores mean? 
7.3             2nd para. An extra ' in "'cc-service-retention".
7.3             Last para: "also contain also"->"contain also".
8                2nd para below figure: "is the where the"->"is where the"
9.11           "to to avoid"->"to avoid"
11              What does ">" mean in 3rd line?
12.1           There is a missing reference at second line.
