[N1/CM6] 3CX disconnects after a rather short period of time (maybe 45 mins?). I have to bring it to the front. I haven't examined in any amount of detail, but I think that the mere fact of bringing 3CX in the foreground is enough to re-register. Unfortunately there is no way to tell that the communication is broken as the icon remains green (not red, nor yellow). I end up with a call routed thru GSM... This was not an issue with the previous release. Sipdroid stays alive. -- A GREAT feature of 3CX is that incoming GSM calls appear to be routed to GSM voicemail. Using sipdroid I often had a GSM call coming in. If 3CX could keep the data link alive, I would make the switch.
