Client has a MICS 5.1 with a digital set in a warehouse area. He wanted to swap out the T7208 for a cordless phone. I installed an ATA and put in a cordless phone. It works well, but now he would like to have both. My dilemma is this: How can I give him one extension to call, ring both the 7208 and the cordless phone, but have an unanswered call end up in the mailbox of the 7208?
