I have the 110 set up with Google Voice. The physical phone is working fine.], both makes and receives calls as it should I have both xlite and 3cx installed on my computer They both register/connect to OBITALK and enable themselves. But neither will make a phone call. I always get a busy signal and a message FAILED TO ESTABLISH CALL. I have checked and double checked the settings, opened ports, tried variations on the settings and nothing works. Anybody have any ideas?
