Here is what I noticed.
My Obi ATA was set to the wrong timezone. I never realized that. My Panasonic Cordless phone has a time setting. I will set the time on it corrected to the timezone(EST/EDT), but it will always go back to the timezone which was set in Obi (PST).
This kept happening until I changed the timezone setting on Obi and the time is now correct on my handsets.
My question is what is the protocol/mechanism that Obi uses to communicate time settings to the Panasonic. I wasn't aware of any such protocols.
Thanks
