As Gordon said, the Nokia's E series (also some N series) are fare the 
best for this. I use an E65 as main phone; if I'm connected to a WLAN it 
connect automatically to my Asterisk and all calls are then VOIP. If I'm 
not near a WLAN, it switched to GSM _without_ any setup modification.

For incoming calls -terminated to our Asterisk- if the Nokia is "online" 
I receive the calls in VoIP. If he's not in the range, calls are 
forwarded to E65 via GSM number of SIM card. Advantage: you give one 
number -your landline number- to customers, your mobile phone number is 
keeped secret.

We even push the setup further: our GSM subscription include free calls 
between our GSM mobile and a landline number. The number we gave is 
terminated to our Asterisk. On an incoming call, Asterisk is checking if 
caller is one of our employees. If yes, we then have voicemenu allow us 
to call any number from our dialplan in VoIP.

Before using E65 we had O2 hardware with Windows CE5 (didn't test the 
CE6, on the todo list). Two problems:

. SIP softwares were not integrated, so if the phone is in suspend mode, 
a SIP incoming call don't wake up the phone
. none of the tested softwares could use the speakers from the GSM 
device, they all used the externals one which has as consequence that it 
could be used only with a headset.
