Just because some implementations don't do what the spec says it doesn't mean it's vague: it means people don't read things and implement them properly :-) > The Tel: Uri allows other characters, especially the "+". it allows those defined by telephone-subscriber in rfc2806, with the exception called out in 19.1.2: The telephone-subscriber subset of the user component has special escaping considerations. The set of characters not reserved in the RFC 2806 [9] description of telephone-subscriber contains a number of characters in various syntax elements that need to be escaped when used in SIP URIs. Any characters occurring in a telephone-subscriber that do not appear in an expansion of the BNF for the user rule MUST be escaped. ~ Theo _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
