FW: 47th IETF: SIP323 BOF

Hi, Dave and All:

Yes, discussions are going on in many groups including the group that you
have mentioned. I guess that most intense in-depth technical discussions are
going on in those groups. However, some discussions also overflow in the
SG16 reflector.

It is up to the people to decide how they participate in those groups
including the SG16 reflector.

Best regards,
Radhika R. Roy
