Thank you Richard, this is very helpful context. The pointers to the FCC,
ATIS/SIP Forum and BT material are a valuable contribution to the broader
community input we are gathering on the current role and relevance of

implementation examples that you think are relevant, I would be keen to
receive them. Many thanks again for sharing this. Best regards,
Hisham
