Pulse to dtmf converter for phones

Featured Replies

I getting really p*ssed with 6 year old Studio DECT handsets. You can't have a conversation on them that lasts more than half an hour without the rechargable batteries going flat and various other defects, including loss of characters on the LCD screens.

Frankly, although they are "Feature-packed" I never use half the facilities and they are irritating to use. I'm looking for something much simpler, better designed and ergnomic.

Any ideas ?

Also, I have a beautifully designed, weighted and balanced "My bel" dialpad-in-handset phone, which is 25 years old, in good condition, and has an illuminated keypad (which still works) and was, i recall, £10 from Argos - best buy I ever made. I would like to use this in the place of the modern carp. But although it has a keypad, the signal output is in pulse. Whilst pulse dialling is still supported on the exchanges here, you run into difficulty when you want to access a bell-tone actuated menu system at any of these call-centres. Is there a pulse to DMTF tone device that I can add in-line to make this phone full functional on the modern phone system ?

In passing I see that there are loads of reproductions of pulse and bell phones of the 1950s, 1960s, and 1970's - the 300, 740, Mayfair, Princess, Trimphone, the scandiphone - the ergnomic design of which I rate compared with the modern stuff. I'd go for one of these over the modern rubbish. Trouble is most the reproducers have gone for cheap plastic, not properly weighted base units and push-button dial-pad super-imposed on a mock dial. For **** sake, do it properly. Is there anybody supplying the genuine article re-furbished to a reasonable standard ?

It strikes me that the current standard of phone design has retreated into the dark ages

You can literally get everything on eBay

They are all stateside and want anything between $50-65 (£30-40) for one unit. That's a bit pricey for what they are.

I was hoping to get one over here or , at least, perhaps get a circuit diagram and make one-up myself.

That ebay link is in the UK?

You can get DTMF generator speaker control thingies, or at least you used to. Small battery powered device with a numeric keypad and a loudspeaker you press against the handset. Push a button, device generates tone sent down the mic of your phone and bingo :)

You can buy refurbed original items from quite a few places, but I've not seen any which don't also use the original circuitry so they're still pulse.

Rather than buying a converter, couldn't you use both phones? Then you have a nice ergonomic phone for conversing on, and a tone phone for when you need to use any "pure-touchtone" services.

That's exactly what i'm doing at the moment, and its a bit of a nause. what's more when I put the digital phone back in its base station during a conversation it tends to drop the connection, So I was looking for one of those in-line devices that connections between the telephone and the wall socket, But there don't appear to be any UK sources for same.

Have you had a look at the batteries - I've got a pair of BT DECT (THINK IT'S DIVERSE 2000) handsets - which started to case problems , and after changing batteries are now OK -batteries from ALDI - AT £2.97 PER FOUR- so that's a pair of phones now back up for less than £3

Replaced batteries last night - see how it goes. Sainsburies wanted £8 for 4 ! Think I'll be visiting Aldi more often.

Oh-and if you're like me - remember to leave the handsets off the base occasionally- to let the batteries get a chance to cycle ,and make them last longer .

Yeh, they don't like being on constant charge like any other re-chargable battery. Maplins do a range of batteries for cordless phones
