Re: Re: SUA::Address Parameter in CLDT

Hi Stu,

Not for connection-oriented.  Also, for connectionless there is never
a need to perform translation in the reverse direction as you describe,
regardless of the size of the point code numbering space, since the
BEGIN always contains either the originating point code in the calling
party address field or in the MTP routing label and this, coupled with
the originating SSN, is always sufficient for routing the response.
