[SR-Users] probles with listen advertise address trying to be resolved

I have a problem when trying to add an advertised address in Kamailio 5.4.2 we have a checf config that is populating various variable. some of these are for the Listeners we have this working and Im getting all protocols for the listeners based on the non _TLS Vars but the TLS config is trying to resolve ADVERTISE_NAT_ADDRESS_TLS. If I try and quote the variable "ADVERTISE_NAT_ADDRESS_TLS" id get an error saying 1.2.3.4:5061 is not resolvable therefroe I have udp,tcp and tls listeners all on the default ports where i need the tls on port 5061 ans not 5060 listen LISTEN_EXTERNAL_SOCKET advertise ADVERTISE_NAT_ADDRESS name = "ext" listen LISTEN_INTERNAL_SOCKET  name = "int" listen LISTEN_EXTERNAL_SOCKET_TLS advertise  name = "ext-tls" listen LISTEN_INTERNAL_SOCKET_TLS  name = "int-tls" the Vars are defined as #!define TOPO_NAT #!substdef "!LISTEN_EXTERNAL_SOCKET!10.10.10.10:5060!g" #!substdef "!LISTEN_INTERNAL_SOCKET!10.10.10.10:5080!g" #!substdef "!ADVERTISE_NAT_ADDRESS!1.2.3.4:5060!g" #!define ENABLE_TLS #!define TLS_CONFIG_FILE "chef-managed/tls.cfg" #!substdef "!LISTEN_EXTERNAL_SOCKET_TLS!tls:10.225.73.16:5061!g" #!substdef "!LISTEN_INTERNAL_SOCKET_TLS!tls:10.225.73.16:5061!g" #!substdef "!ADVERTISE_NAT_ADDRESS_TLS!1.2.3.4:5061!g" REgards, Richard
