我正在尝试连接到Unify OpenScape Business并监控来电。从我目前的发现来看，最好的方法似乎是使用CSTA协议。
在下一页http://wiki.unify.com/wiki/Developer_Program_-_OpenScape_Voice我找到了openscape-sta-sdk-1.5.2zip：http://wiki.unify.com/images/4/47/openscape-csta-sdk-1.5.2.zip
现在我正在尝试基于SDK中的示例来建立连接。我的OpenScape在8800端口上侦听。然而，当我在该端口上telnet或在大约20秒后通过附带的示例应用程序连接时，我会收到一些垃圾。
当基于SDK的监控代码启动时，它会在日志中显示类似的内容：

我收到的垃圾是（十六进制转储的）
61 44 cb 87 07 06 05 2b 0c 20 c3 9a 01 cb 98 03 02 01 02 c5 81 05 cb 98 03 02 01 20 ef bf bd 02 06 e2 82 ac c5 9e 1c cb 98 1a c2 a0 18 cb 87 16 04 09 4d 2d 4f 4d 31 30 2e 30 30 04 09 33 2e 30 2e 30 2e 30 35 37 c4 be 0b 28 09 c2 a0 07 c2 a0 05 03 03 20 10 20
这让我得出结论，我不一定要寻找8800端口上的连接，但我找不到其他连接。
我收到的"垃圾"可能是ASN.1编码的消息，但我无法正确解码。
要监控的代码附在下面，

我还在sourceforge上找到了CSTA客户端，但它也无法监控设备。
我也试着在Unify论坛上发布一个问题，但遗憾的是，这是我见过的程序最糟糕的论坛，简而言之，我不能在那里发布我的问题，这就是我试图在这里寻求帮助的方式。
我正在寻找一些关于通过CSTA访问OpenScape业务V5的提示。如果有人已经为我指明了正确的方向，我将不胜感激，谢谢。
进度，步骤1
也许有人和我一样有类似的问题。。。我会先发布最新消息。
我取得了一些进展，还没有完全成功，但有一点曙光：-）我通过SDK解决这个问题的主要方法是错误的。没有SDK。我终于在这里找到了一些文档http://wiki.unify.com/wiki/Developer_Program_-_OpenScape_4000.正确对话的描述在该页面上的CSTA3_ADG1.pdf中给出，http://wiki.unify.com/images/1/11/Application_Guide_%28part_I%29.zip
此外，我设法获得了CSTA浏览器工具，这对理解asn.1与PBX的通信非常有帮助。我认为值得注意的是，通信应该是什么样子的，下面是在Unify（西门子）的工具CSTA浏览器中进行的"对话模拟"的转储

在模拟之后，我可以向CSTA PBX发送和aCSE.aarq消息。现在我把它存储在一个简单的数组中，比如：
int[] aCSEaarq = {0x60, 0x31, 0xA1, 0x07, 0x06, 0x05, 0x2B, 0x0C, 0x00, 0x81, 0x5A, 0x8A, 0x02, 0x06, 0x80, 0xAC, 0x15, 0xA2, 0x13, 0xA0, 0x11, 0xA0, 0x0F, 0x04, 0x06, 0x41, 0x4D, 0x48, 0x4F, 0x53, 0x54, 0x04, 0x05, 0x37, 0x37, 0x37, 0x37, 0x37, 0xBE, 0x0B, 0x28, 0x09, 0xA0, 0x07, 0xA0, 0x05, 0x03, 0x03, 0x00, 0x10, 0x00};
当用PBX发送数据时，重要的是计算其长度并将其作为前两个字节传递。
如果我这样做，我会立即得到答案。因此，来自我的简单java的对话转储看起来是这样的：
doWrite [aCSE.aarq]

这与CSTA浏览器模拟非常相似。
现在我正在尝试了解如何对消息进行编码/解码。我想我必须使用asn.1编译器来实现这一点，但我还不知道如何正确地执行它，以及从哪里获取asn1源文件。当谈到编译器时，我更喜欢使用免费的解决方案。
您说您正试图与Unify OpenScape Business PBX设备进行通信。OpenScape Business系列PBX设备不是用BER消息而不是XML消息通信吗？
我认为您使用的Java API只是用于OpenScape Voice系列，这是一个使用XML消息的不同PBX系列。
因此，您可能正在向不知道如何处理XML消息的PBX设备发送XML消息。
简单的答案是，你需要知道asn.1协议是如何工作的（ITU-T X.680、X.690和X.890等），之后你需要ECMA-285 csta第3阶段文档、ACSE协议文档（用于pbx登录-ITU Rec.X.227（ISO 8650）、X.217（ISO 8649）），然后你就可以对asn.1进行编码/解码了。Unify csta文档将告诉您，pbx实际支持什么。但我想你现在已经知道这一切了。对于Hipath系统，csta端口为7001（至少需要LIM卡），对于OSB，端口为8800（需要增强卡/服务器）
