How to build an auto-dialing system?

Question

Asterisk

It is required to create a reliable predictive dialer based on Asterisk. We currently use a system that includes Wombat and Asterisk, but we do not consider it convenient - Wombat has a bad API and cannot be used without routine manual operations through its panel.
Need a system that:
- Can be used exclusively via API or direct database queries (adding listings to a campaign, updating listings, starting and stopping campaigns, etc.) so that it can be fully integrated into an existing product
- Free, or paid regardless of the number of calls and operators
- Considered reliable
- Capable of processing tens of thousands of calls per day

Answer 1

Good afternoon
There is experience in implementing a similar project for the power grid through asterisk call files.
The logic is approximately the following: there is a list of debtors who need to be called and reminded of the debt and the need to pay, the list is loaded into the database and "dial-up" is launched, the phone number, the amount of the debt and the date of the debt are taken from the database, we enter the data into the call file and send it to asterisk for processing , using the agi script, we tell the necessary information to clients, simultaneously collecting and processing the statistics of those who answered, so as not to call the same client several times or not to constantly call the switched off phone.
Implemented in php (web interface script for generating call files) + perl (asterisk agi), the load is not large, about 3-4 thousand calls per day (apparently not many debtors).

Answer 2

if the question is still relevant
There is an application built on asterisk.net. (works via AMI) Data is stored in mysql\postgres\ of your choice. the system takes into account the number of operators on the line and the number of free ones. volumes of 300,000 outgoing calls per month are maintained for 5 months.
