We have a voice mail pro having licenses for 4 channels.We noticed that this solution can only support four concurrent incoming calls at a time and the fifth caller gets disconnected.I need callers to be able to listen to announcement and press DTMF digits from their mobile phone to be routed to seated agents.Can i route this calls to hunt group directly if i am not ready to buy any additional licenses for now ?. I am searching for an easy way out and will appreciate your suggestions.
