I have an E71 that I got recently with the intent of getting a 3G only service and using a VoIP provider for calls. Got gizmo set up online and got the beta going on my phone.
It works great most of the time but one thing I keep noticing is that my net phone connection will be randomly dropped. It's using the SIP profile (with auto registration on) that Gizmo sets up automatically for VoIP.
So far I've been unable to find what's triggering the loss of connection other than it potentially trying to switch over to a WLAN connection despite the SIP's default being my 3G connection. Anyone else having issues like this? I usually have to restart the phone just to get it to reconnect via 3G.
