I was using traditional landline with the BSNL Fiber connection for almost 3 months with no issues at all. I was able to make and recieve calls without issues at all. But since the past 2 weeks my landphone is not working , no dial tone nothing just simply dead.. I tried switching the instrument with 2 other landphones, to know whether my landphone is at fault but the result is same.If this is due to some misconfiguration with VOIP settings in the modem settings can anyone please help me?.. If possible can anyone share screenshots of the VOIP settings whoo have their landphones working with BSNL Fibre. Anyone suggestions are deeply welcome since i am using the landphone wihin the home greatly due to low coverage in my area.. Please help me??
