asterisk-1.4.18 and zaptel-1.4.9 and A1200p

遇到一点麻烦````各位帮个忙```先谢
配置如下:
asterisk -1.4.18
zaptel-1.4.9
centOS 4.5
kernel-2.6.9-34.0.2.ELsmp

问题:

当电话打进时，接听到的ivr的声音特别刺耳，杂音比较多.

试过的办法:
1) 配置了zaptel.conf 的参数
2) 把zaptel卡的驱动重新编译了一次

ps:换上4口的卡，没有出现上述问题

zapata.conf 参数修改过的，只能说效果好一点点，没有很大的提搞
比起4口的卡效果差很远

你的电脑硬件是什么配置的？换一个pci插槽会不会还有问题？
16 years 1 month ago #777 by sky
电脑配置
主板:华硕p5gc
cpu: intel 双核1.6G
内存1g
长城电源350w

换了一个pci是一样的，因为我们这边有12口，8口的卡，换卡了都不行
对了，我这里还一个问题：

用一台intel主板的服务器安装12口的卡，只要加载了opvxa1200驱动``系统立马就死掉。asterisk相应的配置跟上面是一样的.
