many-to-many relationship in H.248

Hi

In H.248 single MGC normally works with several MGs. However a particular MG works with a single MGC in any given moment of time.

In a particular setup with which we are working it is necessary that an MGC instructs an MG to give notifications to a different MGC.

Does somebody know a way to achieve this in current H.248?

Do you think such way should be defined?

Thanks, Sasha
