TELCO types, I have a question

So, I figure someone out there knows the answer to this, and I’ll share my guess, but I can’t find an answer on the internet.

My Question: Why does my cell phone ignore (or add) a “1” with a phone call, but my POTS* line phone doesn’t. Not only does it not just ignore unnecessary “1”s, it makes the annoying tri-tone and tells me it’s not necessary to dial a 1.

Well, if you know it’s not necessary, why not ignore it and put the call through?


My guess: the equipment being used is so old it cannot be taught new ticks, but I’d be interested in an informed answer.

*Plain Old Telephone System (I found this when getting my first DSL line).
