Who called from 2694772235

This is a recorded call offering to install a security system. They keep calling my phone at work. I've lost count of how many times they have called.

Me as well ... scammers

phoned a business number  - "not a sales call" - yeah right!
"you have been recommended by a friend or neighbor" to phone me at work? NONSENSE

Keeps calling my cellphone. Robot talks a bunch of non sense. I feel harassed.

This is not a sales call. You have been refereed... etc. It's the Home Security company wanting to let you know that there is crime in your area. LOL Yes it is a sales call where they try to get your address so they can break in when you aren't there. If you are especially ignorant they will get your CC numbers too.
Save yourself the hassle and don't answer or just hang up.
