RouterOS - non-existent routes when changing the link, VOIP does not work, how to solve the problem?

Question

VoIP

Goodnight.
And again a question about the wonderful Mikrotik.
There are two links, reservation. There are several VoIP trunks.
The problem is the following - the router, when changing the link (automatically or manually, it does not matter), does not clear the route table, as a result, open trunk connections try to go through the gateway, which no longer exists.
More details here .
It helps to distort the interface (yes, the only one accessible remotely) or reboot.
They wrote that in 6.5 this was eliminated, I have 6.4 - there is a problem.
Who has an older version, how about this, please unsubscribe!
Thank you!

Answer 1

I unsubscribe. It's the 21st century in the yard and the Mikrtik OS version is already 6.10. I do not understand the desire of some people to engage in necrophilia.
