This was a call purportedly from Comcast regarding a recent installation.  The caller began with the "this call may be recorded for purposes of quality or training."   I told them I was a recent subscriber but to f$^( -off, in so many words, for calling me and announcing that for what?

Did not recognize so did not answer.  They left a message regarding my recent installation and to introduce me to various options and services available.  Not really a nuisance, but a customer service followup after installation.  No big deal.
