Wednesday, July 29, 2020: 2000. ProjectMF was originally started by Phiber Optik in 2006. ProjectMF 2.0 is an adapted version that is compatible with the latest versions of Asterisk (an open-source telephony toolkit), compatible on all hardware with no software recompilation or hardware modifications. It is a self-contained piece of software using band-pass filters and level gates to ensure it works 100 percent of the time. ProjectMF 2.0 is a piece of software that, when combined with Asterisk, can allow MF signaling, ACTS signaling for payphones, 2600 supervision, and SF signaling, It is able to detect OSPS Tones like ringback, coin collect/return, and finally and very impressively, it is able to decode rotary phone pulse dialing sounds! So you can use a rotary phone on any VoIP ATA or channel bank in the world! This gives anyone access to rotary phones on any piece of equipment! It even allows rotary phones on POTS lines to navigate your Asterisk IVR!

When you couple all of this with the open source NPSTN phone network ( - a VoIP phone network for telephone phreaks, collectors, professionals, and hobbyists), then something great happens. All of a sudden, you can dial a number, and MF will come on the line and signal in real time to the remote switch. Once the call is connected, you can do crazy stuff like blue-boxing on the trunk, You can literally flash your switch hook and cause a reset on the "circuit."

NPSTN also has real live operators in a handful of countries across the world, They have around 40 active members and switches on the network, They have ACTS coin-trunks, real crossbar and step switches, and any type of signaling used on the phone network of the 1970s that you can imagine! You can easily move from an intercept message to a secret party-line conference. NPSTN is truly the best "simulation" of the old phone network.

This talk will give you a thorough tour of the magic of ProjectMF 2.0, NPSTN, and the world of phone phreaks, past, present, and future.
