Thanks Dave. I'm essentially trying to build a service in one country where there is no DID provider. If DIDs were available for such countries, that would have done the job. <br><br>Using the two-numbers-per-SIM approach would help significantly, if I could only figure out, how to detect the Called Number using AT commands or Unsolicited Result codes. I was hoping the CLIP code could give me this information, but I'm still struggling to if it does or not. Any idea?<br>

Hi Max,<br>
<br>
Some operators (e.g. Orange in the UK) will allow you to have two<br>
numbers attached to one SIM, which might get you 4/10ths of the way to<br>
your goal.<br>
<br>
I'm struggling to see why purchasing DIDs won't help, unless your FS box<br>
has no internet connectivity. A bit more background on the problem<br>
might help with finding a solution?<br>
