Two VLANS to another place. Voip + Data

Thank you my friend for your answer.
In the example is only with ONE bridge.
I need to bridges, coming from different ETH… JOIN in a single ETH (I think 2 VLANS) and after in the another equipment, SEPARATE it.

I will disable RSTP… but, I don;t understand something from the example..
/interface bridge
add name=bridge1 vlan-filtering=yes
/interface bridge port
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=ether2
/interface bridge vlan
add bridge=bridge1 tagged=ether1,ether2 vlan-ids=10

How can I put in one side, for example ETH3 to bridge2? and after put together for example in eth5?

Is this?

/interface bridge
add name=bridge2 vlan-filtering=yes
/interface bridge port
add bridge=bridge2 interface=ether3
/interface bridge vlan
add bridge=bridge2 tagged=ether3 vlan-ids=20

And if is correct… how can I join both vlan in the eth5?

And remember, the traffic from eth1, 2 and 3 is without any tag!

Thank you a lot.
