多了一个C 出来。还是要改代码。

太感谢了，能帮我修改一下吗？或者告诉我怎么修改？怎么去掉那个c?

hello, 来电显示的问题已经解决了

这是 debug 信息，我从我们公司到过去的。来电显示可以正常工作了。你的 zaptel-1.4.10 asterisk-1.4.20. 如果要改动的千万把 chan_zap.c 和 wctdm.c 先做备份。

非常感谢！！！！！
无以言表~~~

刚才确实看到电话号码过来了，可是我reboot了一下机器
又不行了，怎么回事呢？

hello,
你每次加载驱动时要加 modprobe wctdm cidbeforering=1 cidbuflen=1
