This seems to be your combination of call supplier. I use sipgate and have no issuse whatsoever in this situation. I can have calls coming in with either SIP or Cell then another at same time ringing with the other and all handled as expected.
I just tried sipgate with google voice, I added it to my forwarding phone successfully, but same thing happened like using Gizmo. So i don't think this is the supplier's problem. It must be something to do with phone.

I am having this same issue. SIPgate and T-Mobile. When my wife calls me at work with my GV number, my SIP rings, but as soon as I hit ACCEPT, both calls disconnect. Actually, 50-50 chance whether I get 1 missed call or 2.
I seem to remember hearing there's some way to change the number of rings before voicemail picks up on t-mobile. I also seem to remember hearing that it's different for prepaid than for regular t-mobile. I wonder if a couple of extra rings would help?
This is exactly what I was planning on doing when I received my phone (forward all calls to my tmobile prepaid, and sipgate account, and then answer depending on if I had wifi or not.
Is there some way to ignore regular phone calls when on wifi?
I don't know how to code for the n900, but a simple switch on the desktop to change which devices calls are forwarded to would be awesome. I could write something to change which devices are active in google voice, but I have no clue how to make a button on the desktop run these scripts...
I've been performing more experiments with this today, looking at more configurations in GV and on the phone, switching between CallCentric and SipGate, etc. I called my GV number with my wife's phone. I noticed that the disconnect happens right at the moment when my T-Mobile voicemail kicks in.
Anybody else notice this? I'm hoping that if we all experience this it could be a clue.

The disconnect is definitely happening right after my t-mobile voicemail picks up.
I am using a t-mobile and sipgate account. One starts ringing, and then when the other call comes in, they both disconnect, and the caller is redirected to my t-mobile voicemail.
I have a workaround where I disable my cell phone radio whenever I am on my home network. This is accomplished through a script in /etc/network/if-up.d/ and /etc/network/if-down.d/ I can post them if anyone is interested.
This makes it so only my sip phone rings when I am at home, and my cell phone rings elsewhere (and has the added bonus of saving power when I am at home). Does anyone know how to disable an account using a command?
