SMS Payment Provider for Bulgaria

Hello, Negotiate with two suppliers of SMS payments in Bulgaria - VoiceCom and SMSzona. I'm still not decided with who are working. To choose one of two I want to be sure there will be no problem to make mе module to work with the system of chosen provider. So far, the scales are tipped in favor of SMSzona. but I want to know can you make a module to work with their system? They haven't technical documentation in English. but they gave me the following explanation of how their system works. --------------------- The principle of operation is as follows: Upon receipt of an incoming SMS by some operators, it record in the _smsout table and is called through the Web (via HTTP protocol) script for notification. Script not receives any parameters, the system just turns to him to start it. His work is as follows - must connect to the database with user/pass and to check are there new SMSes in the _smsout table. This can be done in the following example query: SELECT * FROM <_smsout table name> WHERE rem = ''; Then the script performs the processing of text according to the logic of the site and sends (optional) SMS reverse the instructions above. Then it should be noted that the current SMS is processed. For this purpose use field 'rem' as follows: UPDATE <_smsout table name> SET rem = 'ok' WHERE id = ; System is unlikely can not to call the script for notification (because of any failure on the Internet). It is therefore desirable to run in cron (through 5 minutes) to verify the meantime whether it has reached a new SMS. It is good to protect against co-launch 2 or more times. Field 'respc' in the _smsout table is decreasing counter - how many SMSes could be sent to phone number to the user. Sample script for processing SMSes can be found at: http://smszona.com/demo/smszonapro.php.txt Programmers can prepare your scripts based on the information above.
