Notes :

At the current time (Aug 2019) all junction calls go via the Norchard Dell Desktop PC using something called IAX2 Trunks (IAX2 is an Asterisk Protocol, similar to SIP but designed to carry audio more efficiently. Routing everything via the Norchard Dell Desktop PC simplifies the configuration of PBXs at this point in time.
A Home ATA call to Parkend 4399 would route the call via the Internet to the Norchard Dell Desktop PC PBX. This in turn routes the call over the Internet to the Parkend Pi.

January 2020
Here are the latest VoIP Schematics.

Main changes are that Norchard now has 3 digital PBXs.
One serves our home SIP phones and home ATAs and serves dial-a-disk on 4416 and Thomas on 4402 and the Speaking Clock on 4400 and 4403
The seconde serves Ext 4500-4599
The third acts as a fairly dumb gateway between the digital PBXs and the Strowger and will output the speaking clock on LineOut for Strowger when I get time to reinstate Paul's work
