In chan_sip.c I find the following: if (!peer && autocreatepeer) { /* Create peer if we have autocreate mode enabled */ And } else if (!strcasecmp(v->name, "autocreatepeer")) { autocreatepeer = ast_true(v->value); --------- Could someone please explain this, since there's no documentation on this option. Any examples on usage? Regards, /Olle
