通过计算机接听和路由电话

Question

我自愿为一个政治运动工作。我们想制作一个统一的号码（多行）作为联系我们的号码。

我们希望它像客户支持号码一样工作，您拨打一个固定号码（很可能是短号码）会收到一条预先录制的消息，并且这个呼叫被路由到许多其他电话中的一个。

我们向电信公司询问了这个解决方案。他们为它提供飞涨的价格。

我想一些简单的事情。我想获得多线号码，并将其直接连接到计算机，该计算机将呼叫转发到任何免费的在线聊天服务（Skype、msn、gtalk，...）

是否有任何计算机软件（开源/便宜）可以做到这一点？或做类似的事情？即使它为单条电话线执行此操作。

Answer 1

是的，有一种软件/硬件可以实现这一点，而且相对便宜。Asterisk是一款开源（免费）PBX 软件，它可以满足您的需求等等。尽管有预打包的虚拟机设备可用，但 Asterisk 通常用于 linux。还有很多 Asterisk 衍生物，如PbxInAFlash、TrixBox等，它们与各种附加组件打包在一起。

In addition, you need a hardware to connect your phones to a computer. Like LinkSys PAP2 (really old, but can be bought second-hand cheaply), which can connect two phones. There are bigger devices that can connect more phones, or you can buy a dozen PAP2s (they are network-connected, and scale ok).

However, judging your expertise from your question, putting everything together does require a certain level of technical expertise that you probably don't have. So getting outside help is probably a good idea. But you certainly don't need to pay your telco's prices.

What you will pay for

1. Cost of the hardware: Computer + VoIP adapters to connect phones to the PBX. Depends on the number of phones, but generally $20 per phone is a fair price if you need 2-10. Any generic computer made in the last 5 years will handle the 5-10 simultaneous calls ok.

2. Cost of network traffic. Depends of number of simultaneous calls and call quality. Your basic home-level broadband internet connection can probably handle 5 simultaneous calls ok.

3. Cost of DID (incoming phone number). Generally very cheap ($5/mo), but if you need vanity number (1-800-CALL-ME), then the sky is the limit.

4. Cost of incoming calls (per minute, depends on country, generally way cheaper than what your telco quotes).

5. Cost of the technician setting things up.
