I would like an API to communicate with a GSM modem. The reason for this is that, I would like to send talk time from my bulk sim airtime to other numbers. I would like this operation to be triggered automatically by a POST or GET request. The API should be able to log every transaction to log! The transaction on the modem side will by issuing a USSD command. I have read and have been able to connect to modems via SSH through the COM port. At least that is a starting point. I would like the application to be developed in PHP for easy integration with my other apps. Unless you can show me the advantages of developing it in another language. Please view the attachment for how I would like the APP to work. Please also advise if I can do multiple concurrent transactions with this approach, if not, them there will have to be use of multiple modems and this consideration has to be done in the development of the APP. Multi modem handling where it will be able to choose the modem which is not busy for the transaction and also a method of queuing the transactions if all modems are busy. All transactions have to be logged to the database.
