When we do a blind call transfer, the phone rings but if the customer doesn’t answer the phone it cuts the caller off instead of sending the call to the voice mail box If I call the customer’s extension directly and the no answers calls go straight into her voice mail box. Are we hitting a software bug ? Thanks ---

Any voicemail redirection is done by the dialplan you provide (it might also be supplied by a GUI, but you didn’t mention a GUI, and you should ask Asterisk GUI questions on an appropriate forum). A CLI trace would help to show where the dialplan is going wrong. The dialplan would have to go outj of its way to behave differently for a blind transfer. The only relevant state would be a channel variable and possibly the use of a different context. The details of transfer handling differ between real SIP transfers and Asterisk features transfers. Some SIP phones implement blind transfers as attended transfers, under the hood.
