Re: [Sigtran] Sigtran interworking issue between multivendor node

Hi Gitam,

I am assuming that the open MGW and AOIP BSC are connection over the IPSP communication type. Correct if I am wrong?

IPSP is point to point communication so DAUD is not expected message on IPSP communication mode.

So the receiving end point must drop the DAUD message and also this end point can optionally send back Management Error  message with error as "Unexpected Message".

Same can be inferred from section "3.8.1" from rfc4666 as below:

Off course the more experienced experts can comment and put more light on this topic and correct me if needed.


+++++++++++++++++++++++++++++++++++
The "Unexpected Message" error MAY be sent if a defined and
   recognized message is received that is not expected in the current
   state (in some cases, the ASP may optionally silently discard the
   message and not send an Error message).
+++++++++++++++++++++++++++++++++++++++++++

Best Regards,
Pradeep Kumar
