Worked with OOMA support, and so far have done the following:
Cleared out all callerid info on the phone set
Disconnected the phone set from OOMA hooked it back up to land line, get callerid info just fine.
There are no splitters on the phone port on the Telo device.
There is no RJ11 cable running from the wall port to any phone jack.
I have 1 GE Dect 6.0 base unit plugged into Telo, and 2 other wireless devices that connect to the base unit.
Changed the RJ11 cables running from Telo to the base unit.
There are no fax machines, or any other devices hooked up to Telo, basic setup.
Support says they can't guarentee a phone set to work on the Telo device, but this is pretty simple.
MY OOMA contacts list is very well populated, with my callers.
I do not have a corded phone available to me that I can try.
I would like to get this working before I drop my land line, or go out and buy a new cordless setup.
Did the caller Id ever work with any phone connected to the Ooma Telo?
I don't know the answer to your problem, but if your Ooma Telo caller Id worked at your Summer home, but doesn’t now at your winter home, it's been reported that some times to get your Ooma profile updated properly, you have to remove power from the Ooma device for 20 minutes, and repower Ooma device, up to three times before everything functions properly.
If that is the case, caller ID will be problematic.
The solution is to call customer support and switch to standalone mode where they issue you a temporary (or permanent) phone number.
