I don't know if anyone has come across the following problem:
I am trying to send to a customer the sip2sip call in the format
6300#30xxxxx and the call fails.
I am reading the rfc 2396 paragrapth 2.4.3:
The control characters in the US-ASCII coded character set are not
used within a URI, both because they are non-printable and because
they are likely to be misinterpreted by some control mechanisms.
control = <US-ASCII coded characters 00-1F and 7F hexadecimal>
The space character is excluded because significant spaces may
disappear and insignificant spaces may be introduced when URI are
transcribed or typeset or subjected to the treatment of word-
processing programs. Whitespace is also used to delimit URI in many
contexts.
space = <US-ASCII coded character 20 hexadecimal>
The angle-bracket "<" and ">" and double-quote (") characters are
excluded because they are often used as the delimiters around URI in
text documents and protocol fields. The character "#" is excluded
because it is used to delimit a URI from a fragment identifier in URI
references (Section 4). The percent character "%" is excluded because
it is used for the encoding of escaped characters.
delims = "<" | ">" | "#" | "%" | <">
Other characters are excluded because gateways and other transport
agents are known to sometimes modify such characters, or they are
used as delimiters.
unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`"
Data corresponding to excluded characters must be escaped in order to
be properly represented within a URI.
Can it be the case that vendors are not obliged to meet the above requirement?
If yes the # key should never be used on the prefix use.
