sip:1234@192.168.1.1/2 calls to sip uri via account 2).

the SIP Proxy or Registrar address.
Test Call – display a dialog box enabling you to make a test call to a selected phone number, see below.

will not be applied.

periodically sent registration requests. The SIP Registrar can alter the value without letting you know.
