I have a customer that has set up for their auto attendant to answer up front. The caller hear's "you have reached abc company, please hold while your call is being transferred, thank you". There are no options built in the CS just that message and then it transfers on the NO DTMF output to Group 601 which rings everywhere. Recently they've had callers tell them that after listening to the message and telling them to hold while their call is transferred, they are put into voicemail to leave a message. No one is on the phone and none of the phones ring. I cannot replicate this as it works every single time I call in. Any ideas?
