I purchased a new "wired" phone for our house which actually connects through a Koodo ZTE WF721 home phone hub. I am noticing that all calls come through with a 1 in front of the caller ID number, which results in a broken up display, eg. 905-779-xxxx is displayed as 190-577-9xxxx (where xxxx=the last four digits of the displayed number). I am not sure if this a function of the phone or the Koodo service. Anyone have any ideas about this? The wired phone is an ATT CL2902.
