There is the possibility that you can attack the company's switch,
possibly getting into it and reconfigure lines or phone features.
Depending on how the phone system is set up, there are possibilities for
other mischief - some setups let you use the phone as a hub for computer
network connectivity. With a little effort you may be able to spoof a
target VoIP phone, or possibly the boot/tftp server and serve your own
config and code to any phones that are booting up. The possibilities are
nearly endless unless the VoIP network has had a lot of serious thought
and effort into how it has been built and secured.
