Just set the system hold recall timer to 000 and it will not recall any place. It's located in the system timer section of the manny. Keep in mind there is still nothing that can be done when all the phones in a department are busy, phones have to ring some place.
With that said TS is correct you are about to enter into an area that could affect the system in a negative way.
I know how it is when money is tight but imagine what the cost will be if it really gets out of hand.
Keep in mind that if all phones in a group are busy you should have them roll to voicemail and not another group otherwise you will never be able to stop the ringing. Phone systems are designed as a fail safe to keep a caller in the system until you or they release the call.
Maybe you should talk to the bakery about there hold habits. Customers dont like it for more than a minute or two and I would hate to lose customers over lack communication. Just a thought
by the way
