我正在对 Polycom SoundPoint IP 550 进行故障排除。我已经擦除了手机的硬盘（通过菜单选项），现在它卡在重启周期中。显然，设置手机固件的唯一方法是使用引导服务器。
有谁知道另一种设置电话/固件的方法？
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/Asterisk 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
