Ideally the user=phone should be part of the SIP URL. So it should be
within the bracket of from and to header
To: <sip:192.168.0.247:5060;user=phone>
Look in the grammar and syntax section of rfc3261
------------------------------------------------------------------------
-----------
uri-parameters = *( ";" uri-parameter)
uri-parameter = transport-param / user-param / method-param
/ ttl-param / maddr-param / lr-param / other-param
....
user-param = "user=" ( "phone" / "ip" / other-user)
------------------------------------------------------------------------
-------
name-addr = [ display-name ] LAQUOT addr-spec RAQUOT
addr-spec = SIP-URI / SIPS-URI / absoluteURI
-------------------------------------------------------------
To = ( "To" / "t" ) HCOLON ( name-addr
/ addr-spec ) *( SEMI to-param )
to-param = tag-param / generic-param
------------------------------------------------------------------------
----------
So the above form is correct

Subject: [Sip-implementors] "To: <sip:192.168.0.247:5060;user=phone>"
field is valid ?
Hello,
When I make a call from a Siemens handset to SJPhone (softphone), I
notice something strange in the "To:" field in the INVITE request.
This field looks like this:
To: <sip:192.168.0.247:5060;user=phone>
Is this really a valid notation?? I am writing a parser that reads these
headers but I am unsure how to interpret this...
I would expect the To field to look like this:
To: <sip:192.168.0.247:5060>;user=phone
Cheers,
Alex
