What is ZigZag Dialing?

ZigZag Dialing® is Koncert’s intelligent dialing method where the platform calls only one phone number for a contact at a time—never all numbers simultaneously. This prevents call blasting and ensures every outreach attempt feels professional, respectful, and customer-friendly.

How It Works

1: Start with the primary number

The dialer initiates the call with the best phone number first (typically the mobile, which connects 61% more often).

2: Instant, lag-free connection

If the prospect answers, Koncert’s Quick Connect transfers the call to the rep immediately—no dead air, no delay, no robotic pause.

3: If no connection… ZigZag

  • If the number is busy, unanswered, or goes to voicemail,

  • The dialer zigzags to the next valid number for that contact or

  • Moves forward to the next prospect’s primary number.

At no point does the system dial multiple numbers for the same person at the same time.

Why It Matters

ZigZag Dialing preserves a positive Customer Experience (CX) by:

  • Avoiding the spammy feel of simultaneous multi-number calling

  • Preventing prospects from being overwhelmed

  • Reducing spam flags and protecting Caller ID reputation

  • Improving conversation quality and first impressions

  • Maintaining a respectful, human-like dialing pattern

Koncert’s dialers (AI Parallel Dialer and AI Power Dialer) never blast all phone numbers for a contact at once. Instead, they use intelligent ZigZag Dialing to maintain quality and respect while still delivering industry-leading speed and efficiency.

ZigZag Dialing is Koncert’s smart, sequential dialing approach that replaces call blasting with a clean, one-number-at-a-time experience—improving CX, conversation outcomes, and connect rates.
