Hi Jimmy, Not being an expert in this but depending on the standards used Kamailio should also be able to be useful for implementing 5G Voice over new Radio (VoNR) infrastructures. There is of course no ready configuration or implementation available as open source. On our business directory there are a few companies also do work in the IMS space https://www.kamailio.org/w/business-directory/ You could contact e.g. them if they have already something planned here.
