duplicating phone and ring voltage

Sounds good, but so far the cheapest one was 114 plus S&H. Maybe I'll find the model you saw.

I can handle this.

This sounds good, but I need to have it explained in simpler words. :(

Multivibrator?

25Hz inverter. All I can think of is the power supply from a tube radio in a 1950 car, that runs off a 6 (or 12) volt battery.

So I have to build it? I can do that but I don't know how. :)

Wow. Over my limit, I think.

Still a lot.

They might ship. I'll check. Thanks a lot.

Sounds reasonable. I had my old machine apart twice, and my friend's wife's machine apart once, to change the tape mechanism drive belts, and I don't think I saw the number for either, but I'll look harder this time. I think I might have seen both sides of the mechanism, but maybe not since I didn't want to un"plug" the microphone from the top half of the case, and there were speaker wires too and maybe button wires.. Thanks.

It made it a lot easier to ask about my friend's machine, since I had fixed it once, and she used it for a few years after that. I don't think she bought her replacement. IIRC it was included with a new job she had.

Hey everyone!

About the cheapest way to generate a ring-voltage problem...

I've seen several "call directors", a box that picks up a ringing line, listens, determines if it's an incoming fax or modem, then sends the signal to the corresponding RJ-11 jack where the actual device is plugged in.

Wouldn't one of these have to generate a ring voltage to get the fax or modem to go off-hook?

Anyone have a schematic for one of these? It might be a rather simple thing to modify one of these for the OP's purpose.

Comments?

Stan.

Hmmm, Digitally there is distinct ring service from Telco. Corresponding device responds when phone rings. Even single line can have different multitple numbers, etc. Talk to Telco rep. and express your service needs.

Here's a simple inverter-

But to get more control over frequency you may need a more complex circuit using an astable multivibrator or timer IC like a 555.

Of all the advice I;ve see so far, the one that makes the most sense was the person questioning why you need to know the old remote access code to change it. The ones that I've had were set on the base unit and you could do it without knowing the old code.

No way in hell I'd spend hours rigging crap to try to salvage a 20 year old answering machine when you can buy a new one for $20

Found this in google for a Code-a-Phone model 2600.

"Not sure of the model number, but it sounds familiar. If it is the little black one with gold trim and the digital outgoing message, then the remote code is determinded by two things; a sticker on the bottom with a single digit (ie '7') and a switch with two numbers. ('3' or '9') The sticker determines the first digit, the switch selects the second digit. This may be true for yours, look on the bottom for a sticker with a single number; then look for the switch, it may be hidden."

So you have another identical unit? Is it an analogue type, ie does it use microcassettes rather than flash memory? If so, then there may be a small 8-pin serial EEPROM that stores the code and speed dial numbers (?), in which case you could swap the chip between the two machines. You could also read the chips using a device programmer and compare the contents, or you could simply duplicate a working chip.

Thanks a lot, this could be very helpful. I don't have the machine in front of me right now, but I will look for these things.

Microcassettes.

Not important, but it doesn't have a phone attached. That is one of the reasons my friend doesn't use it anymore.

I will look for the EEPROM.

*simply* duplicate? I don't think I can do that. ;-) But the rest of it sounds possible. Thanks a lot.
