📞 CSC Transcribe — Voice Call Upload

Upload a customer-service phone-call recording. The portal forwards it to the n8n CSC Transcribe — Upload webhook, which transcribes via Azure Speech, generates an LLM summary, and posts the result back to the matching Zammad ticket.

Configuration missing: CSC_TRANSCRIBE_API_KEY is not set on this portal. Uploads will be rejected with HTTP 500 until an operator adds it to .env and restarts the apps service.
Allowed: m4a, mp3, mp4, wav. Max 100 MB.
Customer's phone number, with country code.
If provided, the AI summary is appended to that ticket. If left blank, a new ticket is auto-created.
