Proper Pleading Procedures

Civil Practice Law and Rules section 2101(d) states that the attorney issuing papers must sign the papers and include an address and telephone number. If a party is not represented by counsel, the party is to include this information. Improprieties are presumed waived unless the receiving party returns the papers in two days or less with a "statement of particular objections." (CPLR 2101(f)). Defects are to be disregarded if a substantial right of a party is not prejudiced.

Now...how do I return papers to complain about the lack of an address or telephone number if the papers don't include an address or telephone number? How do I serve responsive pleadings, which I think a fairly substantial right of the respondent, without an address or telephone number? There's some circular logic at work here.
