Voip with NAT

[marciourakawa]

I would like to set up a NAT for a VoIP phone to work on the LAN.

Interfaces
WAN 10.208.10.0/24
LAN 192.168.0.0/23
OPT1 10.208.1.0/24

The voip phones that i have work on the network 10.208.1.0/24 from the same network as the OPT1 interface.

But i have VOIP phone that in particular on the LAN 192.168.0.1/23, this equipment should use an OPT1 interface network to reach the gateway of this network 10.208.1.254.

Could someone tell me a solution?
