Q.1     My phone bills have been erratic for last several months even though I have STD locked .
           How do I get my problems redressed ?

 Ans. In Calcutta Telephones we now also provide Dynamic Locking facility to STD barred phone
          lines.

          In case you are a NET surfer, please check your Internet usage. Make it a habit that after you
          close your Browser, check to disconnect the Internet dial-up connection.

          Having provided Dynamic Locking facility, it is the responsibility of the subscriber to apply
          dynamic locking vigorously and guard properly the secrecy of his dynamic locking password.
          For this purpose certain safeguards are suggested.

     (a)  avoid sharing of dynamic locking password with anyone even near and  dear ones in the
             family.

     (b)  avoid unlocking / locking of dynamic locking password in presence of any other onlooker.

     (c)  Change the password at fairly regular intervals.

     (d)  If the subscriber is using a feature phone with LCD display, after each locking / unlocking
            operation he / she should lift the receiver again and dial some other casual digit say the
            digit “1”, and replace the handset. This would prevent display of the locking / unlocking
            password by pressing the last number re-dial key available on such phone instruments.

    (e)  Do not select a  very easy to re-number password ( e.g. 1234, or your birth date, marriage
           date etc.) which can be rather easily guessed by your near and dear ones.

 A good approach is to select two numbers that are easy to remember for you .  Add them or subtract them and use the resulting 4-digit number as the password.

    (f)  Do not keep your password unlocked for long periods of time and be very  careful if you are
          using a cordless phone. While locking lock either by dialing the last digit as “2” ( Trunk call
          & Internet access barred ) or the last digit  as “4” ( all o/g calls barred ).

   (g)  If the line goes faulty with the dynamic locking password in unlocked condition, immediately
          get in touch with DE/Internal of your exchange.

   (h)  A very good alternative to be saved from hassles of probable STD misuse is to have the line
          STD barred and use VCC or ACC for making STD calls. A VCC is a pre-paid calling card and
          ACC is a pre-paid phome call account .

Q.2    Is it possible to get local call details ?

Ans.  No. Due to technical reasons it is not possible to store all local call details although it is done           so for STD / ISD calls.
