I come to know the we can access IP Phone through the hyper-terminal. But i would like to know that how we can access the console. If i wanted to any special Cable or any other things i can use. And one more thing also i would interested to know that how we can upgrade the firmware through this way.
For the upgrade process, look for the firmware version and READ the release notes for it.
In our site we have plenty of documentation for this process.
