[Spce-user] Contact header Replace - MOdify

[Leopoldo Iglesia]

I know, but there is no propperly implemented endopoint, cause all are 
the same way, endpoints are provided by the ftth operator and all 
behaves the same way. This is why I need to do this, and, i tried with 
Contact=........ but no modification at all.

If a put a middleware instance I´ll have the same problem, the how-to do 
it ;)
