Greetings Fred et al, I had a couple of inquiries concerning use of the Beh=
ave WG NAT-PT algorithms:


1)      I was wondering what vendors currently are implementing the Behave =
WG's NAT-PT algorithms?

2)      Has anyone had any experience testing or implementing the stateless=
 algorithm for use cases involving IMS SIPv4 VoIP clients calling SIPv6 cli=
ents and vice versa.  Such use cases assume an architecture where there is =
a co-existence period in the network consisting of both "legacy" SIPv4 clie=
nts and "newer" SIPv6 (dual-stack and/or v6-only) clients.

3)      I'm curious about RTP performance under moderate to heavy call load=
s as well as NAT-PT interaction with IMS-ALG.  If anyone can share at a hig=
h-level that would be great.

Tks,

Len Mosley
