Weird recorded message - guitar, seagulls, British accent

Many of my outbound calls are connecting to a recorded message. I cannot figure out who is doing it. Customer Support here has not been helpful. Has anyone heard this weird message. Some numbers go through just fine, but many more just get this weird recorded message. This is for numbers in the 907 area code (if that matters).

Hm… the link to the recording leads to “404”…

Here is another upload: SndUp | Post Info

Are those numbers from which you get this message in the same telephone exchange (central office), that is, are the three digits following “907” the same?

Or, if they are not, do they belong to the same company or organisation?
