moving/relocating the telephone network interface box (a.k.a. NID)

We switched to Cox phone service for 10+ years now. The Cox technician whom installed the Cox phone modem disconnected the

Verizon wire from the NID and wired in the Cox phone modem. We have to get some electrical work done and the electrician wants to move the NID 12-24 inches; can the electrician move the NID or does some else need to perform the work?
