While you can send both the tuples in the same RRQ (both callSignalAddress
and supportedPrefixes are of type SEQUENCE OF), I am not aware of
a standard way of associating the values in callSignallingAddress with those
in supportedPrefixes.

Two RRQs should work if the alias address specified in both requests are
the same.
