Hi Carlos
is there any different issue with kamailio 4.2.1, because i have the same
error, you solved above, i got the same error with float value
/usr/sbin/kamailio[13336]: WARNING: <core> [rvalue.c:1016]: rval_get_int():
automatic string to int conversion for "0.0005" failed
and with the basic value, it doesn't close the call after 4 seconds
$var(credit) = "4"; # 30$ of credit
$var(cost_per_sec) = "1"; # 1$ per sec
$var(i_pulse) = "1"; # 1$ to establish the call
$var(f_pulse) = "1"; # 1$ per second
