I have been able to configure the OBi110 to make and receive GV calls. I added a Callcentric number for 911, but I also want to be able to call the OBi on that number. It seems like the Netgear WNR2000 is blocking only the Callcentric number and not the GV number, and I cannot get any port forwarding to ring the OBi properly. I tried disabling and enabling basically every option on the router but have had no luck. I don't have the problems of calls dropping that others have had with this router. Any suggestions would be much appreciated.
