A STUN request to the STUN Server on IP A, but now expects an answer back from the STUN Server from IP B.In my screenshots you can clearly see this. In your screenshot, you see 3CX sending 3 request but none coming back.So, from what I can tell, Firewall Checker is correct.[EDIT]Ignore the fact that the STUN Server IPs might be different in your case, we have multiple around the world and different ones are used depending on location... #6 Hello, and thanks once again, I'm also suspecting the SIP ALG on our Sophos XG firewall. Firewall Checker keeps on failing with detecting SIP ALG!!!!!! even though we have disabled it following the steps below: Anyone with Sophos firewall, are these the only steps needed to disable SIP ALG on the Sophos firewall? #7 I think the issue here is not so much that there exists an enabled SIP ALG but that the 3CX PBX is not receiving any replies for the SIP ALG test, that is why the SIP ALG just says "failed" as opposed to "detected". You can also see this from the packet capture as a response to the SIP INVITE sent by the 3CX PBX is never received.Same goes for the SIP PORT 5060 test, the first test for PORT 5060 that does not require a port or ip change passes, however the second test that requires these to change fails as a response is never received by the PBX. That is the reason it reads "Full cone test failed" as opposed to just "failed".That said I think you should check the firewall in order to determine if this traffic is indeed reaching it, and if yes, figure out why it is dropping it or not forwarding it to the correct destination. #8 I think the issue here is not so much that there exists an enabled SIP ALG but that the 3CX PBX is not receiving any replies for the SIP ALG test, that is why the SIP ALG just says "failed" as opposed to "detected".

It tries to interpret packets as SIP and RTP. There is no UDP port filter. To monitor SIP calls

The IVR playback delays are saved to CDR in a custom field Test audio quality (PESQ MOS) in a conference server The conference server should be tested by 2 separate instances of SIP Tester. They can run on the same server on different SIP ports ("LocalSIPPort" setting). The first instance simulates call load of about 30 concurrent calls, it plays silence to the conference. The second instance generates pairs of calls, verifies audio signal and measures PESQ MOS. A pair of calls is generated if you set "number of calls to generate at a time" = "2" Here is a script to simulate the conference in SIP Tester: Test audio quality (PESQ MOS) in a conference server (long-duration calls) SIP Tester should be configured to make N calls in burst, and to limit number of concurrent calls to N. First call in burst plays audio to the conference, secondary calls listen to audio signal from the conference server and measure audio quality Here is a script to simulate the conference in SIP Tester: Test audio quality (PESQ MOS) and DTMF capability of a VoIP route (SIP trunk) in 2 directions The 2 scripts (incoming and outgoing) are used to make test calls via a SIP route to check its audio quality and DTMF passability in 2 ways (from A to B and from B to A) Test outbound dialer The script processes incoming calls which are generated by dialer. It makes random delays, accepts or rejects call. block probability="0.05" >
