In fact the global scenario is as follows:
- Someone calls the general number of the office, and arrives on an auto attendant
- Dependant on the time of call, the AA redirects the call to a message stating that the office is closed, or make the call ring a group of phones.
- If the call is reveived during open hours, the caller should be hearing a message telling him that the call will be treated shortly. At the same time, the phones should be ringing.
The scenario i managed to configure is the same as above, only with one exception. The "Your call will be treated shortly" message is played, then the phones start to ring. So this actually increases the waiting time of the caller (the message is approximately 25 seconds long).
This is why i thought of having a custom ringback tone on the corresponding hunt group.
