I'm wondering.. It looks like I have to also get a SipGate account to make this work with another ATA link the Linksys. When I dial-out via the ATA, do I get charged Sipgate rate, or Google Voice rates? In this case, to get the 2nd line working, would it be best to just get another Obi100 device? I'd like to keep it all in 1 device with the SPA2102 (with 2 phone ports), but I can't seem to find specifics to set this unit up and use google voice for calling out from an analog phone plugged into it, as well as receive calls (to/from my 2 google voice numbers).
In addition to this, Sipgate no longer has any numbers available, so I'm not sure where to go from here..
