Hi Andro.

 

Sure, according to the chapter 25 of RFC3261 - BNF, the address spec of
SIP URI (which is the integrated part of To header) can use a form of
sip:user:password at hostport, the relevant part of rfc:

 

SIP-URI          =  "sip:" [ userinfo ] hostport

                    uri-parameters [ headers ]

userinfo         =  ( user / telephone-subscriber ) [ ":" password ] "@"

user             =  1*( unreserved / escaped / user-unreserved )

user-unreserved  =  "&" / "=" / "+" / "$" / "," / ";" / "?" / "/"

password         =  *( unreserved / escaped /

                    "&" / "=" / "+" / "$" / "," )

hostport         =  host [ ":" port ]

host             =  hostname / IPv4address / IPv6reference

hostname         =  *( domainlabel "." ) toplabel [ "." ]

domainlabel      =  alphanum

                    / alphanum *( alphanum / "-" ) alphanum

 

Best regards,

Hello,  

are you sure that it is correct?
I have some doubt about the use of ":" like in "tester:password". Is it
legal to use a ":" in the To or From URI?

Hi Stephen.

 

Such a message is valid acc. to RFC 3261 BNF. 

Just to be sure I've tried it using our testing tools which are fully
RFC 3261 compatible and the call has been established with any parsing
errors.

 

Best regards.

Hi all,
    Please have a look, is following request valid?
There is a horizontal tab preceding each extra line in To header.

INVITE sip:tester at 192.168.3.104 <mailto:sip%3Atester at 192.168.3.104>

(SDP not shown)

According RFC 3261 section 7.3.1 Header Field Format description,
"Header fields can be extended over multiple lines by preceding each
extra line with at least one SP or horizontal tab (HT)", above request
is valid, right?
