Hello, I think the A query you see is done by the part related to doing OPTIONS keepalive -- I haven't developed that part, but if I remember correctly I saw something like that in the code. Maybe you can disable keepalive via the mod param and see if the query is still done.
For routing, dispatcher is not doing any DNS query, just sets the R-URI or D-URI and then tm is in charge of resolving the destination address, and there should be from NAPTR down, if no transport or port is specified.
