Tough one here:
I added 2 kx-tda7685s to a taw848 system w/dect cs. They seemed to register fine & I added them to the existing PS ring group: had dial tone, grabbed outside line, called other extensions ok. But, when I tried to ring the 2 new PS phones over intercom from another extension, system returned a busy signal.
Then it really got weird: when I called in from an outside CO, the new phones rang, but, when I picked up the outside call, the handset freaked out-- light stuck yellow flashing, softkeys weird, froze. This happened on both of the newly registered handsets. I had to remove the batteries on the handsets to get the phones back to normal. Handsets powered back up ok & displayed their extension number and name, had dial tone. I tried to deregister the units, but the system showed them as not registered. I deleted the base off both handsets which got them back to initial state where phone asks for registration. When I tried to reregister the new extensions (even under different extension numbers), the system is returning error "E0342FF Operation Impossibility". I power cycled the system to no avail. I'm stuck. :shrug: Can someone help me out I hope? I never had trouble registering PS's before. The one PS that was on the system prior to registering these new units works fine. I was thinking to maybe remove the one PS as well as the CS then re-add? Thanks for your help and happy new year to you guys.
