I successfully integrated GV with my ObiTalk110 and ported my landline to GV. It has been working well for a couple weeks, until I accidentally deleted Google Chat under the list of Phones on the Setup, Phones tab of Google Voice. As a consequence I can't dial out or receive calls (though I still get VM). For the life of me, I can't figure out how to Add Google Chat back onto the list of phones. Can anyone tell me how?
