Call just came in - CID listed as USB WARBURG - picked up then held the phone to the TV speaker - they disconnected.
203 is one of the two prefixes for CT.
Caller ID said 'UBS AG", the foreign accent man came on after a wait for the robo call to transfer, and said he was with Solar City or something to that effect.. Told him no thanks, take me off the list. Another telemarketer.
