如何接收电话按键？(300分)

我用ASYNC 3.0接收电话按键。用它附的例程ExVoice时，选择TAPI设备时，显示“The Selected device does not support Voice Extensions.”我用的是MODEM，试了多个品牌，均一样何故？

电信协议有MTP1-3，SS7、TCAP、TUP、ISUP等。
中国现在一般用SS7（7号信令）。
先搞清楚你用的是什么协议。

设置成语音模式
当然你的MODEM 必须支持VOICE

listen

你去更新modem的 driver試試

电话按键时，串口的缓冲区会收到所按的键的ASCII码，好象前面还有一个导引符，
记不大清楚了

设置成“语音模式”后，用超级终端都能看见

实现起来可能很难，因为中国电信接受电话输入信息是通过声讯平台

我的MODEM在接收到电话后，发出的好像是传真信号。什么样的MODEM支持VOICE?
我的MODEM上写着支持语音、传真，可不行！为什么？

First 你的Modem必须有VOICE功能
然后你的MODEM的语音驱动程序必须安装（如果使用TAPI）编程的话
如果直接操纵串口，可先设置成语音应答模式（不同的MODEM）的命令
不一样可查找注册表
HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Class/Modem/001/voiceanswer
如果没有这条命令，说明你的MODEM的驱动程序没有安装正确

用语音卡，很容易实现。

有没有在程序中接受按键号码的方法？

cmldy的回答应该是符合这个问题的，另补充一句，ASYNC 3.0 是用TAPI和MAPI来写
的，因此你的win必须支持TAPI,TAPI 目前只能够在windows98和w2k上实现，win95
需要到http://www.microsoft.com/hwdev/上去下载相应的语音modem驱动程序才
能支持,在 NT 上就不要想了 。

在 NT 上就不要想了 ????
在 NT 上Open Com口按我给出的部序使Modem进入Voice mode完全可以完成此功能。

请问如何在程序中实现?

我在nt上还没试出来，kill-k能给我一个例程吗？谢谢（glrmjcy@sina.com）
