We recently inherited a 3cx phone system with our client. The partner that setup and maintained the system went out of business. The client is a multi location retail store, and has all their store main numbers go to a store specific queue. The queues are setup to ring all agents and max timeout for each caller is 30 seconds. if call is unanswered it goes to a ring group with those same extensions with a ring-all strategy. If it is still unanswered, it goes to their warehouse ring group with ring all strategy. Is there some thing that stands out? Is there a better strategy we can implement to reduce the lost calls?
