  /**
   * Some dial strings in GSM are defined to do non-call setup things, such as modify or query
   * supplementary service settings (eg, call forwarding). These are generally referred to as "MMI
   * codes". We look to see if the dial string contains a valid MMI code (potentially with a dial
   * string at the end as well) and return info here.
   *
   * <p>If the dial string contains no MMI code, we return an instance with only "dialingNumber" set
   *
   * <p>Please see flow chart in TS 22.030 6.5.3.2
