I am new to Kamailio so may be doing something wrong. I looked at https://www.kamailio.org/wiki/cookbooks/5.4.x/core.

I tried the following combinations but getting errors in all cases:

#!subst "/EVAPI_PORT/$env(EVAPI_PORT)/"
#!substdef "/EVAPI_PORT/$env(EVAPI_PORT)/"
#!substdefs "/EVAPI_PORT/$env(EVAPI_PORT)/"

Errors:

 0(6) ERROR: <core> [core/pvapi.c:924]: pv_parse_spec2(): error searching pvar "env"
 0(6) ERROR: <core> [core/pvapi.c:1127]: pv_parse_spec2(): wrong char [E/69] in [$env(EVAPI_PORT)/] at [5 (5)]
 0(6) ERROR: <core> [core/re.c:170]: parse_repl(): bad specifier in replace part /$env(EVAPI_PORT)/
 0(6) ERROR: <core> [core/ppcfg.c:69]: pp_subst_add(): bad subst expression: /EVAPI_PORT/$env(EVAPI_PORT)/

At a later step, I would like to do:

#!define EVAPI_LISTEN "0.0.0.0:EVAPI_PORT"

And use EVAP_LISTEN in mod_param for the evapi module.

And something similar to above for TLS settings.

Hello,

as written on the tracker, look at using #!subst or #!substdef (see core cookbook), they should be able to get the substitution value from environment using $env(NAME).

The master branch introduced #!defenv as a (simpler) alternative.

Cheers,
Daniel

I tried many combinations of the following but I keep getting syntax errors:

listen=tls:TLS_IP:$env(TLS_PORT) advertise PUBLIC_IP:$env(TLS_PORT)

TLS_IP and PUBLIC_IP are constants defined at the top using #!define. And, TLS_PORT is supposed to be the env variable.
