Hi, Edwin!

In this case I think you are right, because the ;user=phone should be an 
URI parameter, not a header parameter. Although the syntax is fine, the 
semantics change - not sure if that bothers you though.

Please open a bug report to keep track of this issue and point it to 
this discussion :).

Best regards,
