Francois,

I do not know of any impact directly. However, it will be necessary to verify what the impact might be, if any.

As an additional though, Q.931 supports two Calling Party IEs. Do we need two calling party structures in ASN.1 for equivalent support?

Bob,

Can you elaborate on why some changes in Q.931 might affect the ASN.1 description?

• If we do accept, by default, the changes to Q.931, do any

of these changes conflict with the ASN.1 coding that we use? If so, how is this resolved?
