Re: DUNA/DAVA/DAUD support for IPSP mode

Hegde,,

RFC 3332 Page 4:

   IP Server Process (IPSP) - A process instance of an IP-based
   application.  An IPSP is essentially the same as an ASP, except that
   it uses M3UA in a point-to-point fashion.  Conceptually, an IPSP does
   not use the services of a Signalling Gateway node.

RFC 3332 Section 3.4.1:

   The DUNA message is sent from an SGP in an SG ...

RFC 3332 Section 3.4.2:

   The DAVA message is sent from an SGP ...

RFC 3332 Section 3.4.3:

   The DAUD message MAY be sent from the ASP to the SGP ...

Because an IPSP does not use the services of an SG, and DUNA/DAVA/DAUD
messages are only exchanged with an SGP in an SG, these messages are
not supported/required in IPSP mode under M3UA.
