Hello. getting used to my new Mics 7.1 & Call pilot..From my 824 DR5 & My old copper nam. Have a question. Ive always wanted the record call feature but on the NAM i was told i would have to Change the class of service which was a pain in the rear.. how do i do it on the Call pilot? is it easy? or do i need to purchase a Key code from a vendor. Under configuration page on IP it just says 10 mailboxes?
