    I'm trying the free version of V11, and we've set up our extensions to forward to our mobile phones. When we dial into the system, our mobiles ring briefly (< 1/2sec), then stop before we can answer the call. A couple of seconds later it does the same thing, and then the incoming call is dropped. The Server Activity Log shows the following:

    Any idea why the system is behaving this way. It's not very useful at the moment!

    Many Thanks,
    Russell

    Is that IP (203.161.160.71) your VoIP provider? The log shows that it is causing the calls to drop. It could be that one or more ports are not open/forwarded on your router/firewall. Did you run the 3Cx firewall check with success? It may also have something to do with the caller ID you are attempting to send out on the trunk (one from the calling party?)

    I'm assuming that any regular call out on the same provider is working?

    You may want to speak to your provider, they may be able to give you a quick explanation about what is happening (if it is in fact them dropping the call). That would save you a lot of time speculating on the cause, and give you more time to try to correct it.

    Thanks for the suggestion. I found that dns.exe was using several of the ports, and once I told it not to, 3CX seems to work fine.

    Thank you for the follow up.. Reminds me I will need to continue training Windows DNS to behave. Sounds like it allocated ports 3CX needed.. like DNS did in Exchange 2003 on an SBS box.. good times.
