Summary: ERROR:parse_from_header
Initial Comment:
The following NOTIFY is rejected because of the format
of the From header:
NOTIFY sip:[EMAIL PROTECTED] SIP/2.0
Via: SIP/2.0/UDP
213.56.166.211:5060;branch=z9hG4bK4475f9dc-7959-8444
Call-Id: [EMAIL PROTECTED]
From: sip:[EMAIL PROTECTED];xxx
To: sip:[EMAIL PROTECTED]
Max-Forwards: 70
CSeq: 6 NOTIFY
Contact: <sip:[EMAIL PROTECTED]:5060>
Subscription-State: active
Content-Length: 0
The From header in this format is not parsed:
From: sip:[EMAIL PROTECTED];xxx
ERROR: parse_to: invalid To - unexpected end of header
in state 22
ERROR:parse_from_header: bad from header
xl_get_from_attr: ERROR cannot parse FROM header
The From header in this format is parsed:
From: sip:[EMAIL PROTECTED];xxx=yy
>From the rfc3261:
>From = ( "From" / "f" ) HCOLON from-spec
from-spec = ( name-addr / addr-spec )
*( SEMI from-param )
addr-spec = SIP-URI / SIPS-URI / absoluteURI
SIP-URI = "sip:" [ userinfo ] hostport
uri-parameters [ headers ]
uri-parameters = *( ";" uri-parameter)
uri-parameter = transport-param / user-param
/ method-param / ttl-param
/ maddr-param / lr-param
/ other-param
other-param = pname [ "=" pvalue ]
The "=" pvalue is optional and therefore both xxx and
xxx=yy params shall be accepted.

Actually xxxx is not an URI param, but a header param.
According to 20.20 (FROM hdr definition), if brackets are
missing, the parameter are considered hdr params and not URI.
For the FROM hdr params:
from-param = tag-param / generic-param
tag-param = "tag" EQUAL token
generic-param = token [ EQUAL gen-value ]
Even if it's a different story, the bug is still valid.
