FYI - SIP-H.323 Interworking BOF

Dear Colleagues,

It is not a bad idea that people should discuss this item as a small group
depending on their interest.

However, if people have a general interest to discuss it in the SG16
reflector, it is their choice. No one individual or a company should
restrict it. Let us understand the norm of using the SG16 reflector first.

Best regards,
Radhika R. Roy
