 > The first I did was tricky, but it works since it before sets the codec
 to GSM to place the request using the command AT+CUSD="<string-number-
 coded-using-current-codec>",<code-for-codec> with the <string-number-
 coded-using-current-codec> in plain ascii text and the <code-for-codec>
 set to the "known" 15 value; then decodes the answer using the current
 codec.

 (that according to GSM 03.38 should be 01001000 and so 72 in decimal).

 I'm still using my implementation, but I figure that I've already given
 all that I know about this.

 My issue:
   - People can not test this in Taiwan as supplementary services are not
 used there.
   - I'm working on something not GTA0X/phone related and didn't have a
 spare cycle to work on this since leaving Taipei...

 The issue with your implementation:
   - Temporarily switching the codec will open a can of worms. It opens a
 race with phonebook and SMS handling. and as an expert in racing I can
 assure you, you will not win this.


 How to proceed:
    - I think the approach taken by the implementation in git (using CUSD,
 specifying a codec, touching the set of files) is the right thing to do.
    - The implementation, e.g. the codec value might be wrong...


 How to continue:
     - Some one with time and a neo might just issue AT+CUSD and change the
 15 to 72 (as from the bug)...
     - Extra points for testing this within a network with supplementary
 services..
