Hi everyone

Mexican carriers have certain "benefits" for their clients like having the possibility to call 4 friends using the same carrier as much as we want for in 5 minute intervals. After 5 min you need to end the call and dial again. The problem is after 5:01 they will start chargin you per minute instead of deducting those minutes from your plan. It will be great if we could have an app that ends a call after a certain duration lets say 4 minutes. If ending only certain calls is not possible then an app that ends All calls after 4 minutes would be appreciated.

I guess there are other carriers that have similar "benefits" and other people can also benefit from this app.
