How to link 2 asterisks?

Question

Asterisk

hello everyone, Help with the following question:
I have 2 floors, one provider, made vlan now 2 floors in the same network (192.168.10.X). Raised asterisk, they gave me an internal (gray ip) from the provider 100.xxx.xxx.xxx, I registered the second address on astrisk and set the gateway 100.xxx.xxx.1 in the settings, registered with the provider for telephony, and then I wanted to connect with asterisk in Volgograd, there is a 10.xxx network, now I can’t ping the Moscow aster, since vpn is tied to the address 192.168.10.x and 10.xxx, And there is no gateway on the asterisk network card in the address settings , the gateway is registered at the second address 100.xxx It turns out that the traffic comes from the second address 100.х.х.х and is unavailable 10.xxx, the second one does not ping from one asteriska.

Answer 1

Having drawn a diagram and thought a little, it turned out that it was necessary to register a static route.

you need to add routes to the required IPs through this hop, and not all
