我们办公室里有几台 Polycom 301，还有 501、601 和 SoundStation 4001。最近，一些 301 和 4001 已经停止向 Trixbox/Ast​​erisk 服务器注册，并且其他手机开始出现这种行为。他们能够联系服务器以获取 IP 地址，联系 TFTP 服务器进行配置，甚至上传调试日志，但注册似乎超时。日志例外如下。有任何想法吗？

Asterisk 1.4.22 Trixbox 2.8.0 Polycom 3.0.1

我们的 IT 服务公司提议重新配置网络以在内部使用 IP 范围 10.10.150.1 – 10.10.150.254，因为他们声明当前使用制造商默认值 192.168.1.x 的 IP 方案“使其易于利用”。

这是真的？知道/不知道内部 IP 方案如何使网络更容易被利用？所有内部系统都位于 SonicWall NAT 和防火墙路由器后面。
