Re: Draft "Sigtran Interworking in ISDN Access Gateways"

Javi,

Here is the last time it appeared on a megaco aggenda:

And then it was no longer discussed.

As I recall, this was in the middle of development of IUA.  The
naming conventions were never adopted (MEGACO avoids such things)
and the rest of the document was too implementation oriented: that
is, it discussed which functions must be inside the box and how they
are to be arranged inside the box.  Also, as I recall, it was
considered undesirable to have MEGACO deal with signalling
particularly when, as in the ISDN D channel case, it is out of band.
That is, IUA instead of MEGACO should be controlling layer 1
termination of D-channels and MEGACO should only be concerned with
the B-channels.  But check through the list of ITU-T packages.

The only thing to come out of it from a SIGTRAN perspective was I
believe the provision of a text interface identifier in IUA.
