Link PTP suggestions

Hello everyone ! … I should make a point-to-point wireless link with two Mikrotik disc lite 5 but I’m a beginner. This Link will be connected to two devices with
Ethernet interface to manage a single electronic device split up as “Control unit” and “Remote unit”. These two devices will be
placed one at home and the other in remote location. They have the default configuration in wired ADSL line, but with the possibility of making some settings such
as IP, DHCP, NETMASK, GATEWAY, SIP contact, SIP PORT and etc.

What do you recommend to do, and what better configuration to load on the Mikrotik Router-board, knowing that the station positioned in home will
assume the ID Master and the remote Slave ?.

In attaching a rough draft.
