如何将 2821 ISR 配置为 PRI 线路上的星号 PBX?

如何将 2821 ISR 配置为 PRI 线路上的星号 PBX?

我正在尝试将我公司的电话系统从 Cisco 的 CUCM 转移到星号解决方案。

我已经设置了 PBXinaflash 服务器,并在 www.vitelity.com 上设置了一个帐户。我能够让它工作。我可以拨打/接听电话,并且它连接到 IVR。

接下来,我购买了带有 PRI 卡的 Cisco 2821 ISR,作为我们当前 VOIP 网关的备份。我能够在其上加载我们当前的配置,并且在插入 PRI 线路后,它就可以与我们的 Cisco CUCM 配合使用。

之后,我用谷歌搜索了如何重新配置​​ 2821。我下载了思科的文档,并在谷歌上找到了一些示例。第一次尝试后,我能够拨打电话。我能够呼叫 IVR 并让它识别我拨打的数字。其他电话的来电 ID 显示了正确的来电者 ID。问题是无法接通来电。到目前为止,我已经让它发出咔嗒声、拨号音、全线忙音,并且没有任何真正的电话响铃。

我的目标是让我们的 Aterisk IVR 接听任何电话号码的所有来电。我们有大约 150 个 DID,但只有 4 个真正用于任何事情。

我的问题是,有人能用这种设置吗?有可能吗?你能和我分享一下你的配置吗?

我认为问题出在 2821 的配置或星号中的中继配置上。

好的,我让它工作了,我需要学习如何使用 2821 ISR 上的调试日志。感谢 freepbx.org 的 SkykingOH 对这个项目的帮助。

使用调试后,我了解到我的电信公司(COX)正在向我发送 7 位中继号码。
