[SIPForum-discussion] SIP Header Validity

[usman chaudhry]

Hello All,

Is it possible to have a "From" header without a User Part. i.e. is the 
following "From" header format valid as per EBNF defined in Section 25 of RFC 
3261.

<sip:74.123.123.201>;tag=3482659391-3XXXXXXXX

P.S
Are there any online tools (i.e. parsers) available, using which SIP header 
validity can be checked.

regards
Usman.
