@shashankb please forgive me if this question was already answered, but I tried to follow this entire thread but wasn't able to get zoiper5 working. I I have the same modem as you and I have disabled wifi and dhcp in LAN, the routing is done by a D-Link DIR-882, by connecting an ethernet cable from AONT 1143 to dlink.The BSNL router has a section called the VOIP for the Landline section
Its in the router Admin page (192.168.1.1)
