We are no longer going to carry the Merlin 410 Phone System, due to their high failure rate.  We are carrying the Merlin Plus system which will allow you to keep your existing Merlin phones and wiring.  This system will allow you the same four lines and up to ten Merlin phones.  You do not need a Feature Package as it has a built in Feature Module.
