Is it possible to connect a provider?

Question

Computer networks

Scheme It is tedious to connect another MTS provider, he gave connection data: Subnet 10.60.104.32/29 IP 10.60.104.34..38 Gate 10.60.104.33 Mask 255.255.255.248 Login and password are not required, this is a normal sip trunk. Without authorization. We cannot refuse two phone numbers from MTS, so we have to work with them. MTS has a dedicated channel and a separate port not connected to our network. Now the situation is as follows, if you make the address 10.0.0.200 and the gateway 10.0.0.1 on Agata, then everything works except for the MTS, if you make the address 10.60.104.34 and the gateway 10.60.104.33, and connect the MTS port and the PBX with a cable, or plug into the internal switch network, then only MTS works.

We have a specific division of duties, I am responsible for the PBX and I don’t know much about networks, but there is an IT department, it is responsible for networks and the Internet, they are trying to set up WAN 2 for MTS on Mikrotik, with a gateway 10.0.0.1, WAN 1 is configured for Internet but unfortunately they can't. It seems that everything goes through WAN 1.
SIP MTS is traced along any of the routes.
Now calling through the PBX (10.0.0.200), I apparently get the SIP MTS, through WAN 1, there are two long beeps, then the IP authorization is probably going on and they send me. Call from the city as if the phone is not connected.
The question is closed here settings Microtik + SIP and SIP trunk setup, voice does not go through?
