All Avaya 5610 phones are getting a double display of incoming caller ID info at the top of the display.They are working behind an IP office 412 which is using a PRI.
Did you get this fixed. I would double check the firmware files of the phone. And maybe reset it.

We have 7 x Avaya 1408 extensions. 6 operate normally, but the 7th doesn't. It can make external calls and receive internal calls, but it doesn't register or ring on incoming external calls. (When idle the display, unlike all the others, does not show the letter G in the top left corner. Is this relevant?)
