OpenSER check setup and Interface Integration

I have installed OpenSER and need everything verified to be working. We would like a front end manager, we are looking at CDRTools, asipto, or OpenSERadmin. We need you to recommend what to use and why. Ideally we want a front end interface that users can login and view CDR, rates, add endpoints, make payments etc. If you have or know of what to use we can go with that suggestion. Previous jobs in this area will have you considered first. Thank you for viewing and bidding :)
