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.
