Intentional or not, the sip-uri (excluding IPv6reference) appears to not violate extending rfc2396's absoluteURI because the definition was a structured subset of opaque_part. However the introduction of brackets to enclose an IPv6 address causes the sip-uri to no longer be a valid absoluteURI (rfc2396) or absolute-URI (rfc3986).
I'm currently not sure if a fix is really needed or how best to correct it. Escaping the brackets might work; however that might cause more headaches. > -----Original Message----- > From: Vijay K.
