I recently installed the new V3 and have got the system working very well... Only I haven't been able to use it for a while because every external inbound call was dropped routinely after 30 seconds, now this was also happening with my phones connected directly my to voip provider, and others with the provider were experiencing the same problem. So i was satisfied it was a problem with the voip provider, and laid a complaint with their helpdesk. I today received an email from them saying the issue had been resolved, so i dialled in from pstn and the call was dropped after 30 seconds... so I wrote back saying that is was still a problem for me. But since then, I have check my phones again connected directly to the voip provider bypassing the 3cx pbx software and the problem is not occuring... but still occuring with the 3cx software. I have run this test multiple times... internal inbound calls are OK. I'm confused, based on the tests I have explained above, it must be 3cx, mustn't it?
