    Sounds like an intervening firewall or router is dropping RTP packets after timing out the port(s). Check the log files of the devices, better yet, get a packet trace.

    Have you forwarded the correct ports
    Check if SIP_ALG is disabled
    After installation have you run the firewall checker?
    Enable the option “Enable Keep Alives” in Settings > General > Global Options

    Hello
    Thanks for your responses.
    I did run the firewall checker and all test show that it is ok.
    May be I 'm wrong here but it works at first but stops working after a minute or 3.
    Then I can no longer hear the other party.
    It is always so that I lose the sound no matter who makes the call.
    To morrow I will try to make a Wireshark trace.
    Thanks so far

    Hello,

    I added a wireshark trace and the activity log.
    Maybe someone will look into this
    I'm not very good in reading traces
    Thanks in advance for you help
    Regards joost
