Hi all, 

These are our conclusions on issue #4: different kinds of payloads...

After double-checking this issue, I want to change my view and align it with Brian's and Kurt's one:

The best option seems to be the implementation of payload 3, avoiding the other two. Reasons for that are:

	- Managing different kinds of payload types is more complicated that only one.

	- When an SS7 message comes from the SS7 network, at the SG, the parameters can be passed in an unpacked way. Therefore the SG doesn't have to unpack before re-formatting them into the payload 3. It can be a straightforward process.

	- It is implementation dependant which format the SS7 application is expecting from MTP3, so that this criteria is no valid for the election.

	- There would be no need to define new payload types to conform to new national variants, since the payload 3 is general enough.

There is no need to keep payload 1 or 2, since the use of them has no benefit regarding to payload 3. Using any other payload than 3, would result in an extra load for the implementation since it should cover all the possibilities. Therefore, payload 3 should replace payload 1 and 2.
