Hello Jenny, you mean, only for this particular module? This can be done with the debugger module: loadmodule "debugger.so" modparam("debugger", "mod_level_mode", 1) modparam("debugger", "mod_hash_size", 5) modparam("debugger", "mod_level", "ims_icscf=3") Cheers, Henning Am 29.05.19 um 17:31 schrieb Trinh, Jenny: Hi, How do I turn on DEBUG level debugging for ICSCF module?
