Your understanding is correct. "As noted earlier, all phone numbers MUST use the global form unless they cannot be represented as such. If the local-number format is used, it MUST be qualified by the 'phone-context' parameter. Effectively, the combination of local number and phone context makes the "tel" URI globally unique." > But the section 7.4 is a bit confusing to the ABNF syntax > of global number. >Does it mean that, if the user dials “00” prefix as an > example (“00919840012345”) and it reaches the server > without a phone-context, do we still need to consider > it as a global number in the server side..? No. It means that is malformed from an RFC 3966 perspective. Thus the receiver can basically handle however it wants. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
