    I recently replaced my Cisco router because of Errors I was receiving. I selected a RV 340 because I have successfully used this series of a cisco router with errors on other 3CX deployments.

    I have confirmed that SIP ALG is disabled on the firewall configuration screen and configured all of the appropriate ports. However, here are the results I get.

    • resolving 'stun-us.3cx.com'... done
    • resolving 'stun2.3cx.com'... done
    • resolving 'stun3.3cx.com'... done
    • resolving 'sip-alg-detector.3cx.com'... done
    • testing 3CX SIP Server... done
      • stopping service... done
      • detecting SIP ALG... detected (received 7c0c52e1 ≠ 9af17011) (How to resolve?)
      • testing port 5060... done
      • starting service... done
    • testing 3CX Tunneling Proxy... done
      • stopping service... done
      • testing port 5090... done
      • starting service... done
    • testing 3CX Media Server... done
      • stopping service... done
      • testing ports [9000..9255]... done
        • testing port 9000... done

    Everything passes except the ALG test.

    As I explained earlier, SIP ALG has been disabled on the router and I am not sure where I go from here.

    Ironically SIP ALG passed with my old router but I had intermittent failures under the media server.

    Any thoughts? I have a SG300 Series Switch and a SF300 Series switch in the mix too.
