English to German Tech/Engineering Telecom(munications) telecommunications

This is an automated dial-out option in some conference call systems; the conference participants' phone numbers are pre-programmed into the system, and the system then calls the participants automatically when it's time for the conference call.

So far, the only thing I've been able to come up with is "automatische Anwahl der Teilnehmer" and various permutations thereof. Google, set to German, came up empty on "blast dial" and simply brought back up the very same English pages it had shown before.

The concept is clear; I'm not overly and totally unhappy with the terms I've come up with, but I thought I'd ask to see if anyone out there has come across a German term for this (or, for that matter, the English term in a German setting).

I can't do a long-winded explanation, using the English term with German in parentheses (or vice versa); these are voice prompts for a conferencing system, so the prompt must be clear, concise and easily understood.

Ideas and suggestions appreciated. MTIA!
