推荐答案

抛开法律问题与不要叫列表确定的唯一方式，如果一个电话是否有效是侦听特定信息音（SIT）承运人推出时，电话被禁用。要自动执行此您使用一种叫做呼叫进行检测或呼叫进程分析（CPA）。你可以用一些IVR系统和开放标准称为呼叫控制XML（CCXML）做到这一点。 Voxeo的有有很大的CPA的IVR平台，你可以尝试一下的在其托管环境免费。看看他们的文档上的外拨呼叫，它会使用CCXML使出站步行通过电话和检测SIT音。在SIT音一个需要注意的是，有些人把反拉客设备在他们的手机，基本上拿出一个SIT音愚弄自动化系统。

Putting aside the legal issues with the "Do Not Call List", the only way to determine if a phone is valid or not is to listen for a Special Information Tones (SIT) that the carrier puts out when the phone is disabled. To automate this you use something called call progress detection or call progress analysis (CPA). You can do this with some IVR systems and the open standard called Call Control XML (CCXML). Voxeo has an IVR platform that has great CPA and you can try it out for free in their hosted environment. Check out their documentation on outbound calling and it will walk you through using CCXML to make outbound calls and detect the SIT tones. One caveat on SIT tones is that some people put anti-soliciting devices on their phones that basically puts out a SIT tone to fool automated systems.
