Dial Timeout

Dial timeout is the maximum number of seconds VICIdial will wait for an outbound call to be answered before disconnecting the attempt and assigning a no-answer dial status. Once the timeout is reached, the call is terminated, the lead is dispositioned accordingly, and the system moves on to the next lead in the hopper.

How It Works in VICIdial

The dial_timeout setting is configured at the campaign level and is measured in seconds. The default value is typically 26 seconds, which corresponds to approximately 4-5 rings on most phone systems. The timeout begins when the call is placed and ends either when the call is answered, when the carrier returns a busy/error signal, or when the configured seconds elapse.

Setting the timeout too short risks hanging up on leads who are reaching for their phone. Setting it too long wastes trunk capacity on calls unlikely to be answered and increases the chance of reaching voicemail, which complicates AMD detection. Most carriers will return a no-answer signal at 30-60 seconds, but VICIdial’s timeout typically fires before the carrier timeout.

The dial timeout also interacts with answering machine detection — calls that connect just before the timeout may not have enough audio for accurate AMD analysis.

Why It Matters

Dial timeout directly impacts campaign efficiency. A well-tuned timeout maximizes the number of calls attempted per hour while capturing leads who answer within a reasonable window. Industry best practice for outbound call centers is 25-30 seconds, balancing the probability of reaching a live person against trunk utilization.

For campaigns with low answer rates, shortening the timeout to 20-22 seconds can significantly increase calls per hour by freeing up lines faster. See the predictive dialer settings guide for dial timeout optimization strategies.
