播放歌曲时，我把呼叫保持 [英] Playing a song when I put a caller on hold

问题描述

我完全是一个小白这方面，有没有可能打一个自定义的音乐主叫方时，我把他搁置在Android中？如果'是'，怎么样？如果不，为什么？我觉得网络运营商有这样的作用，但不是很确定。请指教。

I am totally a noob to this area, is it possible to play a custom music to a caller when I put him on hold in Android? If 'yes', how? If 'no', why? I feel the network operator has a role in this but not very sure. Please enlighten.

推荐答案

是的，你很可能直接从您的手机做到这一点，通过伪造，你把他们搁置，事实上但是这将可能陷入困境的任何电话等待，任第二行，并使用大量的额外的能量，从您的手机电池不必要。

Yes, you could probably do it directly from your phone, by faking the fact that you're putting them on hold, but that would probably mess up any call waiting, any second line, and use lots of extra energy from your phone's battery needlessly.

有一个更好的解决办法是从VoIP服务器播放音乐，并设置线的无条件转移要经过服务器 - 之前，甚至会到您的手机。并不是所有的电话网络将允许你这样做，比如Verizon公司这样做是为了我一次我切换到后付费账户（由prepaid之一）。和Sprint确实对我来说。要看看是否你这样做，看看你的手机网络允许您设置通过谷歌语音无条件转发（看看谷歌语音设置/帮助页）。如果是这样，你设置。只要知道添加一个服务作为一去之间可能会增加一些延迟得到一个电话呼叫的第一环，而这取决于如何好，服务是，它可能会降低一些的声音质量以及（或者不是，它实际上取决于）。

A better solution would be to play the music from a VOIP server, and set up unconditional forwarding of your line to go through that server -- before it even gets to your phone. Not all phone networks will allow you to do that, for instance Verizon did it for me once I switched to a postpaid account (from a prepaid one). And Sprint does it for me. To see if yours does that, see if your phone network allows you to set up unconditional forwarding through Google Voice (take a look at the Google Voice settings/help pages). If it does, you're set. Just realize that adding a service as a go between may add some delay in getting the first rings of a phone call, and depending on how good that service is, it may degrade some of the sound quality as well (or not, it really depends).

和没有，你可能并不需要购买自己的VoIP服务器。你也许可以使用类似 http://tropo.com 或的 http://www.twilio.com ，特别是如果你只是在原型的东西。

And no, you probably don't need to buy your own VOIP server. You could probably use something like http://tropo.com or http://www.twilio.com, especially if you're just prototyping something.
