how to connected two subnets with sonicwall router?

I am introducing a new VoIP system into an existing LAN.
Customer requirements were to keep voice and data separate. We have two data drops for each location, separate POE switches for phones and everything.
Now they want to use some of the desktop features for phones, etc...

The computer subnet is 192.168.1.0 and phone subnet is 192.168.2.0 both with 255.255.255.0

The 1.0 and 2.0 networks are two ports on a SonicWall firewall/router

What do I need on the router to allow the 1.0 pc network to access the phones 2.0 network?

Thanks in advance.
