N spoofed. CID says SDDPC. It seems the scum use this id for a number of calls. This one was a robocall for some health insurance plan. I pushed 1 and immediately got a busy signal. I received an identical robocall from 858569-9765. I pushed 1 and this time, there was a long delay before I got he busy signal. This CID said UNKNOWN CALLER8/6

Robocall about warranty for auto repairs. This call, and many other similar calls, are a S-C-A-M. My best friend on Planet Earth actually signed up for this type of warranty and it was a R-I-P-O-F-F. Unfortunately, there are many bogus companies making these calls. Caveat emptor.
