The Request-URI must be sip:[EMAIL PROTECTED]:11400.
You cannot drop the port part.
RFC3261 Section 16.6:
2. Request-URI
The Request-URI in the copy's start line MUST be replaced with
the URI for this target. If the URI contains any parameters
not allowed in a Request-URI, they MUST be removed.
The 'URI for this target' is the one retrieved from the registrar, i.e.
it is the one originally registered against the AOR. Note that an
explicit port is not a parameter!
