To be more accurate, PER may not work fine through a NAT function. If your firewall doesn't do NAT, then PER should have no problems.

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.
