I have a Cisco RV180w router that I am having problems with the SIP ALG. I have the SIP ALG enable to do NAT but when making calls on VoIP phones in the same network I get no audio. This is telling me that SIP ALG is not working properly and the router is getting confused with a call origniating inside the LAN and calling another phone within the LAN.
I am able to make inbound and outbound calls just not agent to agent when in the same LAN. What other configuration can I go to make this work?
