Recently one of our sites all of the phones manually programmed static IP’s dropped off. The phones seemed to have all resumed a DHCP IP pull from the network. Needless to say they were exiting the building incorrectly so we have to work with the end user to reprogram the phones. I’m not after fixes for this part we know the setup is wrong and are working to fix it (money issues)…
These phones have been in use for at least 4 or maybe 5 years.
My question is there a CMOS battery in them?
We are just trying to figure out why they would lose their manually programmed static like this and this is the only thing I could think of.
D40, D60, D65 models in use here.
