Signal setup

Connect your agent to Signal with a dedicated phone number. You bring the phone number, authorize your own Signal number, complete Signal’s registration checks, and Cohort registers the account on your workspace gateway.

You’ll need two phone numbers: the agent’s dedicated Signal number and your own Signal number. Use full international E.164 format for both, such as +14155550100.

If your gateway doesn’t have durable storage yet, the app will walk you through a quick gateway rebuild (a couple of minutes) before registration.

Before you start

Signal requires a real phone number that can receive an SMS registration code. Twilio and similar providers work, but Cohort does not manage or bill that number for you.

You also need your own Signal number. Your agent answers only messages from that authorized number.

Step 1 — Start the Signal wizard

  1. In Cohort, go to Settings → Channels.
  2. Click Connect on Signal.
  3. Enter the agent phone number.
  4. Enter your Signal number.
  5. Click Continue.

Both numbers must include the leading + and country code.

Step 2 — Complete the Signal captcha

Signal requires a one-time captcha before it sends the SMS registration code.

  1. In the wizard, click Open captcha.
  2. Complete the captcha at Signal’s registration page.
  3. Copy the full signalcaptcha://... token.
  4. Paste it back into Cohort and click Submit captcha.

If Signal rate-limits the registration attempt, the gateway error appears in the wizard. Wait for the rate limit to clear, then try again.

Step 3 — Enter the SMS code

Signal sends a six-digit SMS code to the agent phone number.

  1. Retrieve the code from your phone-number provider.
  2. Enter only the six digits in Cohort.
  3. Click Verify code.

When verification succeeds, the channel is paired.

Step 4 — Test the channel

Open Signal from your authorized number and message the agent’s number. Your agent should reply shortly.

If the agent does not reply:

  • Confirm you messaged the agent number, not your own number.
  • Confirm the message came from the authorized Signal number you entered.
  • Give the gateway a few seconds to finish registration and report health.

Disconnecting Signal

Disconnect the channel in Settings → Channels. Cohort deletes the Signal account registration from the gateway; the phone number itself stays with your provider.
