Asking how many downlight I have in my house.

Caller: Skytech limited sales and marketing

I picked up the call but said nothing. The other party hung up quickly. Probably the computer checks if there is someone there before connecting to the call centre. I rang the number from a landline and got a recording with American accent saying the company name. Added it to the do not respond list. Getting long......... The number ID is probablyfrom a random number generator.

Scam call. Hung up and blocked.

marketing call - called back got a recorded message to press different numbers depending what I wanted to talk about - blocked number

Telemarketing company. Rang once and then hung up.
