Hello, I managed to register to my local number on a fritzbox and to my asterisk line by writing USECALLMANAGER in proxy node under the sipLine and the ip of fritzbox / asterisk in processNodeName . The problem is that I can not register the two lines simultaneously as I can just write one ip on processNodeName and the fritzbox and asterisk have different local Ips, anyone know a workaround to connect two SIP lines simultaneously which host has different ip?
