[Users] Troubles parsing headers

[Daniel-Constantin Mierla]

This trace helped to spot the problem, in the first, the line broke on 
the wrong character.

The empty space ' ' is not allowed after 'sip:'. If there is a space, it 
must be escaped. sip: must be followed by username or domain (see ruri).

Maybe in the configuration of the phone one space is present at 
beginning of username.

Cheers,
Daniel
