docs: This method is the equivalent to the other createSipPhone() method, but using the default
  transport (UDP/IP) and the default SIP port number (5060).
  
  @param host host name or address of the SIP proxy to use. The proxy is used for registering and
  outbound calling on a per-call basis. If this parameter is a null value, any
  registration requests will be sent to the "host" part of the "me" parameter (see below)
  and any attempt to make an outbound call via proxy will fail. If a host name is given
  here, it must resolve to a valid, reachable DNS address.
  @param me "Address of Record" URI of the phone user. Each SipPhone is associated with one user.
  This parameter is used in the "from" header field.
  
  @return A new SipPhone object.
  @throws InvalidArgumentException
