We are a VoIP reseller looking to expand our service offering.
We are looking for someone with strong experience in deploying VoIP solution (preferably Asterisk). This will run on a server hosted in a data center. Features like IVR and DTMF will need to be active. The service should be able to accommodate multiple concurrent calls.
The VoIP server will be integrated to a calling card solution (preferably A2Billing) which need to be designed and setup.
When a user calls an access number, IVR should ask the user to enter calling card pin. AAA process should be completed. Both the USER TELEPHONE NUMBER and PIN should be stored into database for the next phase of this project.
There is bit more to this project. This will be discussed after shortlisting.
Although we specified preferred software, feel free to suggest software you think might be more suitable. This needs to be open source.
Please feel free to let me know if you require further clarification.
