I have a 3G21WZ router (3G) which I've got an IPECS phone on 2talk plugged into. The issue is that after a certain period of time, less than 24 hours, the connection seems to time out somehow, I can make outgoing calls but not receive incoming, they go straight to voicemail. I've searched and it seems to be a fairly common problem, but I'm having trouble fixing it! Is it port triggering that I need, and if so how do I set it up, the below is my attempt so far. Otherwise is it port forwarding, and if so what settings do I need for that? Thanks for any light you can shed.
