Telnyx Expert Needed to Configure Outbound Voice + Connect to Vapi

I already have Telnyx numbers and a Vapi account; what I need now is a clean, working outbound-voice configuration that pushes every call event straight into Zoho CRM. Your job is to:

• Configure Telnyx outbound voice so calls route through Vapi without quality loss.
• Map the Vapi webhooks (ringing, connected, completed, failed, etc.) to Zoho CRM so each call is automatically attached to the right contact/lead.
• Walk me through the setup in a short hand-off call or concise step-by-step doc so I can maintain it going forward.

Everything must happen inside the Telnyx, Vapi, and Zoho environments—no third-party middle layers. If you have existing scripts, Telnyx portal tricks, or Zoho Deluge snippets that speed this up, even better, but please keep the solution maintainable and well-commented.

I’ll provide API keys and a sandbox CRM. Once calls appear in Zoho with correct status and basic call meta, the project is done.
