利用路由器进行isdn拨号问题？

chaike309

我通过cisco2620上安装的isdn模块，连接上isdn NT1对远端的cisco 7200路由器拨号（同样有isdn模块，NT1），但是有的地区能够正常拨号，有的地区不能拨上（山东省，各市向青岛总公司拨号），不知道为什么？

这是下面一家分公司的配置，其他家均同

debug isdn q931
debug dialer的信息如下：

请帮忙看看那个地方有问题！！！谢谢！

sh dialer  显示连接成功了，但我觉得不是正常的连接，它一会就会断掉，也不能ping通对端

BRI0/0 - dialer type = ISDN

还有chap的两端匹配问题．

你的配置里怎么没有逻辑拨号接口，这样做我没有试过，还有你确定callref = 0x2B ；callref = 0xAB 是正确的吗？
