I was trying to get a soft voip phone to work under these credentials of BSNL IP phone ....Like if we throw in the exact configuration on a Soft dialing app ..we might be able to make and receive calls...Can someone help me out on this
suppose you are referring to this :-
Install sipproxd on the Pi and just bridge the WAN of VOIP and LAN of my local device
apt install siproxd
/etc/siproxd.conf
