Hi, since last year in july my voip provider didn't work with 3cx. The voip lines could not be registered. In october, windows made some updates (windowsupdates) - since then 3cx didn't work. Before october there were no problems. But now, after the latest windows updates it is working again - i never changed anything on the settings of 3cx and the server!!! So how could that be? does anyone have an idea??? My voip provider says, that they didn't have changed anything at the configuration. Not in july and not now. AND: X-Lite freeware had during all the time no problems - also not after updates. I don't understand the connection of windows update and 3cx... So i fear that it won't work in a few days/weeks/months after the next update?!? Cause of this problem, we didn't update to version 7. We are using still the latest Version 6. Any ideas???
