Queue Overflow

What Causes This Error

An inbound queue has more callers waiting than can be serviced in a reasonable time, or the queue depth exceeds the maximum configured size. Callers may be receiving busy signals or being routed to overflow destinations. Caused by insufficient agent staffing, high call volume spikes, or agents not taking calls.

How to Fix It

• Check queue status: asterisk -rx ‘queue show QUEUE_NAME’

• Review agents logged in: asterisk -rx ‘queue show QUEUE_NAME’ | grep Members

• 3 If agents are paused, identify why: check agent screens for errors

• 4 Temporarily increase queue timeout to give callers longer wait option

• 5 Route overflow to voicemail or alternate number if agents are insufficient

• 6 Check if agents are being pulled to outbound — adjust blending settings

• 7 Monitor queue stats in VICIdial real-time report

How to Prevent It

Implement queue depth monitoring with alerts. Configure overflow routing for queues (voicemail, alternate number, or time-based routing). Balance outbound dial level against inbound queue coverage in blended operations.
