Hello,
Today, i’ve put a voip server on the network here (IP 10.0.0.10) but it seems that he can’t connect to my VoIP provider (SIP).
At IP >> Firewall >> Connections i see as Src Address the IP and before that IP there is a “U”, so i suppose that this is a part of the solution?
Can somebody take a look at this file and tell me what i’m doing wrong?

I just set up a VoIP server with Mikrotik.
Offhand, I’d say you need to drop the SIP helper. It generally does more harm than good:
/ip firewall service-port disable sip
You will need to configure your VoIP server/phone to play well with NAT. There should be tech docs with your device to describe settings. The general consensus is that NAT and VoIP don’t work well together, but there are workarounds based on individual hardware.
You might also want to use the Torch tool to look at the live traffic to see what is/isn’t flowing out of your interface.
Also. . .
I am a newbie to Mikrotik, but I couldn’t see any forwarding rules in your config that would allow traffic to flow in after your DSTNAT rules.
Something like this:
add chain=forward comment="default configuration" connection-state=established
add chain=forward comment="default configuration" connection-state=related
