Aa basic cell handset reqquires a fair bit of processing power and memory, making custoom ringtoness a no-brainer. Not so with landline sets, which reqquire no memory, and no processing power.
combine this with the fact that fixed handsets are NOT typically operated in a “public” area, so thier ringtones are unlikely to be confused with other handsets, and you can see that there is not areal market for fany ringtones where landline aapplications aree concerned…
We use a set of Uniden cordless phones in the lab, and they have something like 15 different ringtones we can choose from. We’ve got it set up so that the OR and ICU have a different ring, so we know it’s really important that we answer quickly.
As far as I know, though, it’s all just built into the phone and we can’t add any new tones to it.
I was referring to the Jitterbug phone as well. The Jitterbug was a popular dance from the 1930’s which most of their target demographic will fondly pick up on.
Also, check out the new Motophone (although I’d be surprised if it was made available in the US).
In any case, the answer to the OP and your converse is the same. It is trivial in cost to add it to a mobile phone and non-trivial to add it to a analog phone. The US is very price conscious, so it is hard to market a derivative product that is more expensive. On the other hand, why don’t they add this feature to digital answering machines?
