Hi,
According to RFC 3261 19.1.1
"The set of valid telephone-subscriber strings is a subset of valid
user strings."
Since the 'user' info part of SIP URL does not cover "#" symbol
according rfc 3261 syntax for 'user'.
According to RFC 2806, the syntax for telephone-subscriber is
telephone-subscriber= 1*dtmf-digit
dtmf-digit = "*" / "#" / "A" / "B" / "C" / "D"
How can telephone-subscriber string is a subset of valid user string?
Can you please help to resolve the above statement?
Thanks & Regards,
Anil
