Haven't messed with the 7905s in forever and I have a firmware question. It currently has a SIP firmware loaded on the phone and I wanted to get this phone working again on SCCP instead. Now on newer phones a firmware reset is easy but these phones operate differently from what I have read. Is there anyway for me to reflash the phone with the SCCP firmware instead of the SIP? I've tried simply plugging it into the network as a SCCP phone but nothing happens as I expected. Are there any methods to revert this back to SCCP forcibly?
