Strowger PAXes - dialling 30-0-50-91-491

Dialing 30-0-50-91-491 in my front room.
The red phone (GPO 706) is on my AT&E 50/7A PAX.
Dialing 30 takes you out through an outgoing tie line and onto the junction selector, 0 takes you back into the 50/7A on an incoming tie line, 50 takes you out through another tieline and into my asterisk server. 91 are the access digits which take you in to the asterisk server at the Dean Forest Railway, 491 then takes you back into my asterisk server, which then dials "39" on your behalf which takes you out another tie line into my 10/2A PAX and then it finally dials a 5 to ring the black phone (also a 706)
Two 1950s strowger PAXes, a home-brew junction selector, two asterisk servers and a load of internet later - and I've phoned from one side of my front room to the other.
This is what happens when you throw your TV out and find something else to do with your evenings.

Looks good. I may show this to my Dad. He used to work for BT and is renovating some kind of similar old equipment in his shed.

Excellent video!! How would it be if you made a call and you hung one phone up and left the other off the hook? How would the switches work to activate the off hook signal?

Hi Peter - if your Dad needs any spare parts, give me a shout. I may be able to help. If he doesn't already know about it, he may be interested in thg.org.uk
