|Various implementations of prepaid "hotline" for phone-based service are possible on Elgato equipment and according software. One of the schemes: users of your system buy pin-codes for 5, 10 or more minutes of service, call to "hotline", input pin-code and use their servicing time.|
To organize such service you will need equipment and software similiar to listed below:
1. Multichannel VoIP-GSM-gateway Elgato - for accepting incoming GSM-calls.
2. IP-PBX platform - for implementation of voice menu (IVR), users outhentification and users commutation to operators. The system warn users when user minutes limit almost over and disconnects from paid service automatically.
3. Communication channels between operators in office, remote operators and administrators of system.
System cost and functionality depends on number of simulaneous calls necessary (how many users can use system at the same time) and your needs for special functions to be implemented (languages, custom IVR, algorythms or call switching between operators, call-back etc.).
