Basic ASA question

So I'm a storage guy trying to help out while we're between IT guys. Currently, we have an ASA 5506 that has our LAN network 192.168.2.0/24 and our voip network 192.168.40.5/24 directly connected. I'm trying to get it so our local work stations can reach 192.168.40.5 the PBX so they can reach their voicemail GUI. I have them both set up as security level 100 and same-security-traffic permit inter-interface same-security-traffic permit intra-interface both set up. I'm still not able to ping 192.168.40.5 from the 192.168.2.0 network. I can ping it from the ASA. What else do I need to set up? Would I need NAT? Thanks ahead of time.
