I had the green one on the bottom. Tag yourself! 😂

Seriously, it was a bit janky but I was delighted as a teenager that I could disconnect the bell so it wouldn't wake me up if someone called before 11am on a weekend. I can't remember if it was *designed* to be turned off; I definitely opened it up more than once because I could and because there was a loose wire in it.

This is at @connections -- I have so many photos to process!

Hey #telephone people - does anyone have a recording of a call to any of the 1990s "chat and date" services (eg, 0891 505050 - or 0891 343434)

The TV adverts were great, but I didn't have enough money to call one!

I'm told they were a maze like menu system, that took ages before you could chat with anyone

I'd like to make a realistic recreation, so If you have a recording you can share - please DM me! (discretion assured!)

Just sorted out a light-touch refurb on this GPO Tele 745 weatherproof #phone

The handset is a bit faded, scratched and tatty, but it’s had a good clean and a new cord, so it’s perfectly serviceable for #emf2024 and suitable @cutel mischief.

I bought this with the intention of installing it in the garden, it really needs a strip down and repaint… but I can get to all that after #emf 😀

Now this is a nice find!

I've been passed a scan of a notebook from the late 1950s containing details of all the #telephoneExchanges in the UK

This sort of information was used by #telephone enthusiasts (UK #phreaks) to navigate their way around the toll (trunk) network

There were various techniques to get yourself onto a trunk, but once you were there the dialling codes in this notebook would get you anywhere in the country!

My new bedtime reading has arrived…

In the UK, AC13 telephone signalling used pulses of 2280Hz to represent the digits of a dialled phone number, call progress state etc.

This training document from 1983 was pretty late in the lifespan of in-band signalling like this, which had been around for 20+ years by this point.

It’ll be fun reading this from a “what would it do if I poked $thing at $time” point of view

This is extremely silly.

I have a Nokia 105 #phone. No data or apps. Just a plain, dumb, mobile phone

Using a sim from aa.net.uk I've connect it to the C*Net VoIP network https://ckts.info

It's accessible on a CNet number, and can place calls just like any other phone on CNet!

Do I need this?
No.

Can it make normal calls?
Absolutely not!

Is it useful?
Not in the slightest.

Is it cool as heck?
Absolutely!

I'll make a demo video later…

I've just been thoroughly nerd sniped by someone telling me that the #asterisk SMS module supports BT Text, and that it should be possible to make that work on https://ckts.info

I love the product names in this extract from Telephone Rentals document "EP2/4055 - S50 - FACILITIES, DICTATION RECORDING" (30th Nov 1964)

It lists approved suppliers of centralised recording equipment, to be connected to their internal telephone systems

Centralising the recording equipment was much cheaper than duplicating it for each exec.

A central typing pool would retrieve the recordings, type them up and send them out
