I'm evaluating 3cx v7.1 RC2 and whenever voicemail picks up an un-answered call the call can remain connected for exactly 31:27mins. I've found this happens when an incoming caller listens to the message, does nothing for a short period then hangs up. If the caller hangs up quickly or correctly presses the # and 0 the the call terminates correctly. I've read in this forum that a workaround of a 120secs timeout existsts in RC3 but mentions an FXO gateway which I'm not using (I use SIP trunk only), will my problem be fixed by RC3 or is there another solution. Many thanks, Ads.
