ASA 5510 - Routing issues between sub-intefaces

Last Modified: 2015-12-29
Used to have Cisco 1811 as my router and gateway, but had some issue with VPN tunnels, decided to use ASA 5510, 9.1(6), Security Plus lic instead.
Have a network with eth0/0 (internet), eth 0/1 (data) and eth 0/2 (voice).

Issue: I can ping both internal networks from ASA, but not between networks.

interface Ethernet0/0
 nameif outside
 security-level 0
 ip address xxx.xxx.xxx.xxx
interface Ethernet0/1
 nameif inside
 security-level 100
 ip address
interface Ethernet0/2
 nameif voice
 security-level 100
 ip address

Attached is my full config. I'm new to ASA (ok with IOS) and most help I find to resolve is for pre-8.3 ASA.
Thank you!
