D110P 无法打出电话（中国一号信令）

你好，我用楼上的文件替换过后也试着编译了一下，运行到readme的第五步时出错了，仔细查看发现是mfcr2.c中包含的一个头文件#include<zaptel/zaptel.h>
没有出现在当前文件夹下，解决办法：在当前文件夹下新建zaptel文件夹，然后把zaptel-1.4.9下的zaptel.h拷贝到刚才建好的文件夹中，重新编译就可以了，
不知道楼主有没有遇到这样的问题？

谢谢2位的热心帮助。按照你们的指点，问题已解决。谢谢！！

不好意思，又碰到新的问题了。
按照本帖中的方法安装配置完毕后，testcall打电话正常。但是在asterisk下，用unicall拨打电话时出现问题，表现为拨打某些号码（如空号）时，通话正常（可听到语音提示），如果由主叫端挂断，则线路可以正常释放；但如果被叫端先挂断，则中继线路无法释放，造成后续呼叫失败。

主叫端先挂断：

请问这种问题该如何解决？（所有的补丁文件都是在本论坛下载且全部安装）

不是很清楚你说的意思。 主叫一个空号，应该不会建立连接，没有连接，不存在被叫挂机的情况。你能进一步描述清楚你的问题吗？ 另外，用teatcall再重复一下呼叫，连接，挂线具体过程，将信息贴上来

当拨打一个空号或受限制的号码时，远端会播放一个提示音，当提示音结束之前由主叫方挂断，线路可正常释放；当提示音结束之后通话会自动结束，但是中继线路并没有被asterisk释放，用 uc show channels 看时，会发现刚才那条线路的状态为 3XXXX，而不是 idle。

用testcall重复拨打这类号码都很正常，而在asterisk里通过unicall来拨打则会出现线路无法释放的问题。我已经反复安装多次，并更换不同的asterisk版本（包括 astunicall 压缩包里自带的 asterisk-1.4.18），问题依旧。

如果用testcall 测试没有问题，那可能问题出现在asterisk配置。 我们会找时间重现一下。

1。 另外， 从被叫的后向信令上看，并没有向主叫发 空号 代码5，发的是线路空闲 代码 1 。 你能否问一下机房端是什么原因？
