I've been getting calls all afternoon yesterday and again this morning from two numbers, but when I pick them up, they just beep at me, like they're trying to send a fax. One's a Leeds number, and the other is a Sheffield number, 01133822101 and 01142230499 respectively.
I've tried calling them back and they're always engaged. I've tried hanging on, just in case it's one of those irritating auto dial deals which then connects you to a salesperson. If I answer then press buttons on the handset they go silent then disconnect.
Any idea what's going on?
