Added a RV220W in front of my UC540

We switched internet provider to get a 120mbits/20mbits internet connection.  The UC540 is not able to handle more than 30mbits of data on the WAN port.  So I was told to add RV220W in front of the UC540.  I have disable the WAN port on te 540.  I am able to make outgoing calls but no incoming calls are comming in (getting a message that this number is not assigned).  In the RV220W I have added the SIP-TCP and SIP-UDP port forwarding to the UC540.

RV220W has the data dhcp server (

UC540 has the Voice dhcp server ( and has an IP of data lan (

There is a static route in the RV220W from to

In the RV220W I tried adding port forwarding for SIP-(TCP and UDP) to (does not work) and  (does not work)...

Also mught be a VLAN problem but I'm not that great with VLAN...

In the RV220W Wan port I have my internet

RV220W Lan Port1 goes to my DataSwitch

RV220W Lan Port2 goes to UC540 expension port

You can take debug ccsip message on the UC to see if it receives the SIP message.

If it doesn;t, post in "small business router" as the problem would not be with the UC500.
