Are you talking CAP (Computer Attendant Console) or FlexAttendant?
Either way, the answer is no. There is no 3rd party software that I know of for the Coral, nor any other PABX, for this.
How do you mean "crapped out"? If it's merely the software that has become corrupt, uninstalled, or otherwise faulty then just get it back working again. CAP has a dongle based licence - is the dongle plugged in to the PC and also has the PC connected to the APA on the phone?
Likewise with FlexAttendant, it's merely a reinstall of it to get it working if it's stopped.
If you're looking for something a bit more up to date then you could look at Navigator. But most things that have "crapped out" in software terms can be restored. It's not like a physical device has stopoped working.
