Hello,
I am trying to configure a Cisco SPA8000 to function as a SIP ATA behind a RV220W router. I cannot seem to get port forwarding working or otherwise allow the SIP traffic to the SPA8000. When I replace the RV220W with another router / firewall everything works fine, but when I put in the RV220W I am not able to register etc. I have been over and over the manual and "yes" I have the SIP ALG enabled. Here is my setup:
Internet => RV220W (public) => SPA8000 (private)
Can anyone suggest anything please?
Thanks
Chris
P.S. on hold for nearly 3 hours waiting for Cisco support!!

Hi Chris, using the 1.0.4.17 firmware, try to make the port forwarding under the access rules instead of using the port forwarding page.

Tom,
Thanks for the response. I have done so. I have created custom services for the UDP SIP and the UDP RTP ports and added them to the access rules without success. I am in the process of downgrading to the 1.0.3.X firmware.

Chris,
have you managed to get it working?
i'm thinking about similar configuration RV220W and SPA8000.

Yes, I was able to get this working and it has been doing extremely well for about 4 months. The key in my case was to make sure the SIP AGL was ENABLED. The problem was that the service provider's SBC was seeing a non-routable IP address in the SIP header and was requiring a shorter registration interval than the endpoint. The result was that the SBC would eventually deny the connection when the registrations got out of synch.
I can recommend this configuration now and for high SIP traffic (in excess of 12000 minutes per month on 5 channels).

P.S. It was the service provider who insisted that the SIP AGL needed to be disabled in order for our configuration to work with their service!

Of course I mean "ALG" in both places above . . . . . sorry.
