Numeric telephony
MFTel.NET
A closed telephone network where your identity is a number. You dial digits, place calls and write from that number. Matrix is the pipe — events, end-to-end encryption, VoIP; what you see is number, dial, call, recents, contacts.

Exchanges
Hosted exchange, free registration — the exchange assigns a 7-digit number+0 384
Elite series — every number is assigned by the operator, none is drawn from a pool+0 000
Private exchange — a customer's own exchange on their own hardware, isolated, accounts issued by the customeron request
Networks never interconnect. The same digits under different exchanges are different addresses; a leading + is refused — local calls only.
Where it differs from a telephone network
- Knowing a number is not enough to ring it. A call completes only if the caller is already in the callee's contact list; the exchange refuses the invite before the phone rings. Publishing a number does not create a hotline.
- Attractive numbers are stock, not luck. Repdigits, mirrors, sequences and round numbers never come out of the free pool; they are assigned by the operator.
- Groups are closed and encrypted. The owner decides who may add them — their contacts, everyone, or nobody; anyone else sends an invitation. The exchange caps invitations per number per day. A group call rings every member.
- The phone rings when the app is closed. The exchange pushes to the handset itself; no third-party relay sees your calls.
- Contacts live on the exchange and follow you between devices; recents stay on the device.
Sign-in
Number and password
No username, no server picker. Your exchange is fixed in the phone; you enter your number and your password.
The phone is a web app
app.mftel.net installs as a PWA: keypad, messages, contacts, recents, settings. Calls run inside the phone screen with mute, camera, speaker, hold and DTMF.
Support
support@mftel.net. Short number 0001 on +0 384 is the support desk.
