How to set up the following scheme on Mikrotik?

Question

linux

1. Wired provider issues real ip via dhcp
2. Backup channel (USB whistle).
3. Sip phone
4. VPN tunnel
5. Local network 192.168.1.0/24
VPN tunnel must go up through a wired provider, and all traffic from the local network and sip phone must go through it. If the wired link is not available, then the VPN tunnel must go up through the backup link. If it is impossible to raise the tunnel, then direct the traffic through a wired provider or a backup channel.

Answer 1

mikrotik failover

Answer 2

Mikrotik knows how to script, so write one that checks all this and run it every 30 seconds through the scheduler
