I recently networked 2 124ie's. Everything works fine except for the ringing at one location. Extensions only ring once, whether called locally or across the network. The call stays at the phone, flashing the Call key, and can be picked up, but rings once. Virtual extensions do the same thing. Calls do forward properly, even without the ringing. Have reset the phone system and reseated the CPU. Next step is defaulting the database and starting from scratch unless the problem can be found.
