right now I have free 3cx installed in my laptop and still not working though. By the way, thanks for your quick response.How far into the call do calls get dropped. There is some data gathering you'll need to do to find out if its the itsp thats terminating the call or your pbx. This is done by capturing sip traces. See: https://www.3cx.com/3cxacademy/videos/advanced/basic-troubleshooting/
Its not a simple diagnosis. Who did you buy your 3CX license from. Have you checked with them?
I did not open my 3cx since last week because i need some information on how to make it work. Thank you for your response leejor. I will try to use other soft and let's see if my details will work.You first need to determine why the call is dropped (which end is causing it to happen), and, if for the same reason each time. The 3CX Activity log should show this, right after an occurrence.
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
