Summary: ERROR:parse_from_header

Initial Comment:
The following NOTIFY is rejected because of the format
of the From header:

NOTIFY sip:1000801004 at 10.10.10.10 SIP/2.0

The From header in this format is not parsed:

ERROR: parse_to: invalid To -  unexpected end of header
in state 22

The From header in this format is parsed:
From: sip:1000801004 at 10.10.10.10;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.
