Or the other option to use an old pulse dialling telephone is to use a Grandstream TandyTone 5XX/7XX or their current HT8XX series Analogue Terminal Adapter. We have a network with literally thousands of old pulse dialling telephones stretching around the UK and the rest of the World as far as New Zealand. We've been using the technology that BT/OR are moving towards for the last fifteen years! There are about thirty odd servers in the UK with many old pulse dialling phones connected. The 'technology' lets us put old phones virtually anywhere - all the phones in attached photo were connected up and able to dial all around the World as well as between each other using an 8 port Grandstream ATA.

Even BT have a number of lines off my VoIP server which end up on the exchange lines on an old electro-mechanical exchange in Holborn exchange in London. Reason? The PABX was found in 2019 in Leicester Exchange powered up and ready to go but hadn't handled a call since 1985 (all the users had been given those new fangled 'Cellphones' ! ) It was moved to London and reinstalled. However BT wanted to put the original Leicester numbers on the exchange lines but someone had gone and altered Leicester to 0115 xxx-xxxx rather than the 0533 xxxxx from the 1980's. As we still use the old dialling codes and numbering, they came to our network. Plus they liked the fact we don't have 'line rental' or 'call charges' whatever they are? Even Dave M is connected!
