Multiple alerts for Rebound

[jbraun]

We had an old nbx pbx before switching to 3cx. We have employees that work emergency on call and use the rebound feature to send out to a cell phone and if no answer allows the system to take the voice mail. The issue we are having is only getting the one alert, and would like to find a way to be able to have multiple alerts. the old nbx system had a feature to call every 5-10 minutes until you retrieved the message. I know currently there is no feature like this and plan to submit a feature request, but does any one have a work around for this? Any suggestions will be greatly appreciated
