Well, the old MAC address is definitely gone. It was stripped off on ingress. T1 PPP and dial-up don't use MAC addresses, so there won't be a new one as the packet traversse that link. But the packet will end up on a router or access server at the other end probably, which will output the packet to Ethernet or some other LAN probably and put in new MAC addresses.
