I am not 100% sure if its a bug or feature request. And, I have already asked this question in mailing list. ### Description I was trying to pass environment variables to Kamailio that are definitely there in the container. Also, I am trying to use the environment variables to specify ports for Kamailio to listen on. I have already tried passing variables through -A option but to no avail. ### Expected behavior Please note that these values are known at start time so should work. #### Actual observed behavior Errors #### Debugging Data I have tried: ``` #!define TLS_TO_LISTEN tls:TLS_IP:$env(TLS_PORT) ``` I have also tried using in EVAPI `bind_addr` modparam but that throws errors: ``` #!define EVAPI_LISTEN "0.0.0.0:EVAPI_PORT" .. modparam("evapi", "bind_addr", EVAPI_LISTEN ) // IP and port to listen on for incoming TCP connections. ``` Error: ``` ERROR: evapi [evapi_mod.c:156]: mod_init(): invalid port: 0 ``` ### Additional Information ``` version: kamailio 5.4.2 (x86_64/linux) f8885c ``` * **Operating System**: Docker Container: ``` Linux fe1933ee6208 4.15.0-124-generic #127-Ubuntu SMP Fri Nov 6 10:54:43 UTC 2020 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
