I had also some thoughts about it lately and it will be interesting to see SMS on a2billing and certainly not too hard!
In the same way, we do Voip routing we will need a LCR/LCD system that will find the best rates through the providers defined in the system!
It will be fairly as the rate engine we have for Voip in a much more simpler approach of course! Destination, prefix, selling rate, buy rate...
Important, we will need an new API so that you can resell your SMS system to some other users without the need of connecting through the Customer interface and the Customer interface itself will have to use in back end this API to push the SMS.
SmsDR (SMS detail report), I just made it up
will need to be added with status of each sending SMS, well VoiceTrading SMS report always send me failure even if in most cases the SMS is sent correctly.
That was for the quick thoughts!
Who will get the labor done and add this to the trunk ???
Cheers,
