我不相信有天使，没有。但我有个停车小天使它在我的仪表盘上，你给它上发条。翅膀扇动，它就会给你一个停车位。到目前为止，它还挺管用的
比利-康诺利
本章将讨论商务电话环境中常见的几种外围功能。我们将简要介绍features.conf文件，然后花几节讨论寻呼和停车，最后使用 Asterisk 的会议引擎confbridge 做一些工作。
首先，让我们从安装目录中复制 features.conf文件并查看一下：
$ sudo cp ~/src/asterisk-16.<TAB>/configs/samples/features.conf.sample \ /etc/asterisk/features.conf $ sudo chown asterisk:asterisk /etc/asterisk/features.conf
features.conf
Asterisk 提供了与大多数 PBX 通用的若干功能，其中许多功能都有可选参数。您可以在features.conf文件中调整或定义 Asterisk 的各种功能参数。
一般]科
在features.conf 的[general] 部分 中，可以定义选项来微调 Asterisk 转接功能的行为。这些选项与 SIP 电话处理呼叫转移的方式无关。你可以在通话时使用 DTMF 数字来访问这些功能（通话必须是桥接的，因此正在振铃或进行中的通话将无法访问这些功能）。
~/asterisk/文件夹中的features.conf.sample文件包含各种选项的详细信息，以及如何设置这些选项的示例。
这些功能已不像过去那样常用，主要是因为许多这些功能都可以用比从电话机发射 DTMF 更先进的方法来处理（例如，通过某种外部集成，或使用电话本身的内部转接功能）。
特征图]部分
[featuremap] 部分（如表 11-1 所示）允许您定义特定的 DTMF 序列，这些序列将触发通过 或 应用程序中的选项桥接的信道上的功能。您最有可能使用的两个选项是 和 。Dial() Queue() parkcall automixmon
| 选项 | 价值/示例 | 说明 | Dial()/Queue() 标志 |
