    I get these as well, with regularity.

    Only thing I have done to fix it is:

    Turn off Windows Firewall
    Re-install SBC software and don't use encryption
    Change FQDN to Public IP in the configuration file.
    uncomment the localSipAddr


    That seems to help keep that issue from happening.

    I should add that all of those tricks worked in v12 and v14 for that error. The irony being that about 10 minutes after I posted my reply- my audio cut out with this exact issue!

    I"m running v15 on linux and i'm getting pretty consistent issues with my physical phones with one-way audio or no audio.

    The 3CX for Windows clients that are on the same LAN work fine- but the physical phones keep getting this issue, so it is definitely something with the SBC.

    So I got connected with Support and they sent me an internal build of SBC v15 that resolves this problem.

    Apparently, it's a known issue on the current production build of SBC v15.


    Once I installed the build they sent me - all the RTP problems went away.
