I opted for bsnl ftth connection and took modem on rent.Bsnl gave me Huawei echolife hg850a modem and it does not have bridge mode option.So I am running it in pppoe mode and connected TP-Link wr840n router in dynamic mode.Can you please guide me how to configure voip in modem and router so that I can make calls using zoiper or some sort of sip apps.Voip status is still connecting.
