Cannot enable incoming ring tone on Auto Answer

[StellarTX]

I am using PBXtra Version 1.5.14 build 39595 running on Vista and when I have the auto answer function activated - I do not get any inbound call notification or warning.

I have tried to go into options / Alerts and Sounds / and imported some standard windows.wav files that do play when tested on that screen but after selecting "Set as Active Ringtone" .....nothing

You response is most appreciated.
