Hi, I'm unable to make pjsua_acc_modify() change the lock_codec setting. Example: pjsua_acc_config account_cfg = { 0 }; ... account_cfg.lock_codec = 0; printf("account_cfg.lock_codec: %d\n", account_cfg.lock_codec); pj_status_t status = pjsua_acc_modify(account_id, &account_cfg); printf("status: %s, account_cfg.lock_codec: %d\n", status == PJ_SUCCESS ? "success" : "error", account_cfg.lock_codec); status = pjsua_acc_get_config(account_id, tmp_pool, &account_cfg); printf("status: %s, account_cfg.lock_codec: %d\n", status == PJ_SUCCESS ? "success" : "error", account_cfg.lock_codec); Console output: account_cfg.lock_codec: 0 10:54:00.739 pjsua_acc.c !Modifying account 0 status: success, account_cfg.lock_codec: 0 status: success, account_cfg.lock_codec: 1 Is this a bug?
