    Audio issue with Fanvil X3S

    You could also capture a call with wireshark and check whether the audio is coming from your provider with bad quality (in which case not much can be done from your side). Keep in mind that the pbx makes no changes to the level of the volume.

    Solved An IP has been blacklisted :(

    Glad to hear you managed to whitelist your ip. Have in mind that if logging from another ip is not possible, you can wait for the Blacklist Time Interval to be exceeded. If it has not been changed (Setings >> Security >> Blacklist Time Interval) the default value is 1800 seconds (30 minutes).
