I got banned!
May not be shared explicitly, but it would be configured on the device.
Sorry for mistake. I meant Rj11 (landline port jack) not Rj45(it's a ethernet port).@Ameen In starting I was thinking that for using landline we have to connect it to only bsnl's ONT modem (ont's landline port). But then I realised that most of the personal routers also have adsl's Rj45 port (landline port).
So we can use the landline through router's landline port (Rj45 port) along with the internet by LAN by using bridge mode technique and also need to properly configured the VoIP and internet WAN settings in router.
