Hello all those using google voice. If you do the option of the one phone number do have to get a new phone number? Or can you use your existing mobile number as your main number and have that also ring your home number, office number, etc.?
If you just want to utilize the voicemail features, then you don't have to use a new number, but if you want all of your phones to ring simultaneously then callers will need to be dialing your GV number.
Number porting will be supported eventually, and you could then take your existing cell number and use that as your GV number, thus ringing all selected phones.
