Aseem,
This may be true for Q.931, but H.225.0 modifies the related tables found in Q.931. H.225.0 suggests in section 7.2.2 that the encoding shall follow rules in Q.931, but H.225.0 specifies the ordering.
I see no problem with putting those fields at the end, especially considering that inserting new IEs in the middle may be more difficult to handle.
It might be interesting to see what assumptions people have made. Do implementation expect an ordering? Would they expect new elements to be ordered numerically or at the end?
Best Regards, Paul

Hi All
There is a problem in the additions made to Q.931 part of Connect message in H.2250V3. Two new IEs have been added AFTER User-to-User IE.
The IE codes for the new IEs added are: Connected Number : 0x4c Connected Subaddress: 0x4d
The IE code for User-to-User is 0x7e
According to Q.931 coding Rules [section: 4.5.1], the IEs in a message should be in ascending order of their respective code values. These two IEs should be added after Date/Time IE.
