Proof of concept — demo environment, not production. No SLA, no emergency calling (no 911/112), data may be reset without notice. Calls will drop after ~50s as the app is in testing mode.
T9phone

User manual

1. Install the softphone

T9phone uses Acrobits Cloud Softphone as the calling app. Install it on your phone first:

  • iOS: search the App Store for "Cloud Softphone".
  • Android: search the Play Store for "Cloud Softphone".

2. Provision the app

Open the Dashboard. You have two ways in — pick whichever matches the device you are reading the dashboard on:

  • Different device than the phone (laptop, desktop): the QR code contains your one-tap provisioning URL. In Cloud Softphone, pick "Use QR code" on first launch and scan it.
  • Same device as the softphone (you are on the dashboard in your mobile browser): hit the Magic link button right next to the QR. You can't scan your own screen, so the link hands the credentials straight to Cloud Softphone — one tap and you're registered.

Either path ends the same way: the app registers against the T9phone server automatically.

3. Make a call

Open the keypad in Cloud Softphone and dial the recipient's dial code — the digits shown next to their nickname on your dashboard. Tap the call button. The other person's softphone will ring, showing your nickname.

4. Create a group

  1. Go to /groups.
  2. Click New group and name it.
  3. You become the owner.

5. Invite people

From the group panel:

  • By email: type their email, click Send invite. They get a message with an Accept link. If they are not a T9phone user yet, the same link lets them pick a password and join in one step.
  • Link only: click Generate link only to copy a URL you can share over chat. You can also raise the uses counter to issue a multi-use link.

6. Manage the group

  • Rename: changes the display name; the URL slug stays the same.
  • Member cap: caps how many people the group can hold.
  • Kick / Ban: kick removes the member; ban also blocks rejoin until lifted.
  • Activity log: append-only audit trail of joins, leaves, kicks, bans, role changes.
  • Transfer ownership: hands the group over to another member; you become a regular member.

7. Change your nickname

On the dashboard, edit the Nickname card. The new name must be 6–12 lowercase letters. T9phone refuses the change if the new T9 code would collide with someone else in any of your groups and suggests alternatives.

8. Default group

When you belong to more than one group, the dashboard shows a Default group for dialing selector. Pick the group you call most often — plain dial codes resolve in that group first. Use *N*<code> dialing for one-off calls into other groups.
