Pass ANI as an input

  • • Your adapter maps call metadata into callerPhone. TrueServe can author this mapping as callerPhone: $var:ani.
  • • Use a country-code phone number. Ask for a mobile number if ANI is absent or unsuitable for SMS. ANI does not authenticate the customer.

Scope and retries

  • • Let connect_auto_experience create a new acg-auto experience. It grants the four auto tools. The pilot launcher excludes the connection tool.
  • • Generate one stable request_id per connection attempt. The service deduplicates retries and avoids resending after an ambiguous AWS response.

Build the customer web entry

  • • Provision a public HTTPS host for /demo and the browser routes. Its backend must authenticate to private Cloud Run and preserve each browser JWT.
  • • Configure link generation to use that host. Keep operator session creation and MCP access behind their existing authorization checks.

Enable and test SMS

  • • Configure AWS credentials and MULTIMODAL_SMS_ORIGINATION_IDENTITY, then attach connect_auto_experience to the GECX agent.
  • • sms_submitted records AWS acceptance. connected reflects a recent browser SSE connection; test delivery and voice interruption on the target channel.
