By transcoding I meant that specific information fields which contain
identical information but are encoded differently need to be translated
from one format to another.

There's another problem - the use of PER combined with protocol-
embedded addresses greatly complicates operation through firewalls.
Not that I'm a fan of text-based protocols - I absolutely am not.
But PER-encoded signaling streams could force the use of firewall
proxies, which has unfortunate performance implications.
I'm not certain that I understand the point about transcoding -
it's going to have to take place, anyway, whether the megaco protocol
is text-based or not.
