[OT] Seeking headset to plug into phone base unit (via 4P4C)
I want to use a regular headset (earphones & mic) with my landline
phone. The headset would plug into the socket on the phone instead of the curly lead. I'm in the UK and the cost of ready-made telephone headsets are about £30 or £40 which is a bit steep for me. So I guess it should be possible to modify an ordinary headset to terminate with a 4P4C plug which would then go into the curly lead socket on the phone. I'm hoping it's almost as simple as: (a) replace the mic in the original handpiece by the mic in the new headset (b) replace the earphone in the original handpiece by the earphone in the new headset. What special considerations are there about headphone/mic impedance or about any additional components which may be needed? Is there any constructor info or a simple circuit diagram for this? |

Seeking headset to plug into phone base unit (via 4P4C)
I've never tried it (though I keep meaning to...) but the wikipedia
entry for '4p4c' http://en.wikipedia.org/wiki/4P4C has a diagram which shows the 'usual' connections. As Owain says, there is no guarantee about this. I have a Retell Recorders box for recording via the headset lead; it has a six-way switch to allow you to select the right wiring combination! From talking to Retell some years ago I learned than 95% of telephones correspond to their 'setting 1' or 'setting 2'. I haven't got my notes on this to hand but suspect the wikipedia diagram is 'setting 1' and might be worth a try. HTH J^n |

There was a similar thread on UK DIY about this a short while back - but to precis my earlier comments you'd be better off with a Bluetooth-enabled landline phone and a matching headset. I've got a BT Glide and a Sony Akono headset. The phone's a bit cheap and plasticky ( Siemens do a nicer one ) but the setup works a treat - and the range is impressive. It's been weeks since I picked up the old handset. Regards, -- Steve ( out in the sticks ) Email: Take time to reply: timefrom_usenet{at}gmx.net |

I wanted to save on the £30 or £40 for a plug-in headset but the BT Glide is over £150 and you would still need to get a bluetooth headset ontop of that! |

It's been weeks since I picked up the old handset. I think that was me - the requirement was for wireless - and needs a DECT phone When the OP thinks £30-40 is a bit steep, I don't think its a solution -- geoff |

OK, so it was listed as knackered ( no earpiece sound ) - but I figured it probably still worked via a headset, which it did. I took it apart and stuffed in the earpiece speaker out of an old Ericsson...works fine now. No way I'd pay £150 for the Glide. If you can find a shabby one cheap and just use it as a 'headset engine' you might come in on budget. I don't know why the landline Bluetooth phones are so expensive - you can get a Bluetooth enabled mobile for a very great deal less.

But I've got one here unused - the box is a bit tatty but all the bits and manuals are present. You can have it for £45 including carriage. Neil Reply here in first instance.

They are a godsend for the times you have to deal with any government agency, insurance company, bank or credit card company, some reservation processes, and when you need to work a problem with most any pin-head bureaucracy.

I bought a Photonics one new for £65 a couple of months ago But I thought the OP found £30 a bit steep... Traditional headsets/handsets were fairly conventional in the days of rocking armature receivers and carbon transmitters (and even the early electret transmitters), and one could swap readily from handset to headset. Modern 'technology' seems to outlaw all this and demands that you buy a 'high-tech' substitute... -- Frank Erskine |
