Create a queue

A call queue is a waiting line for callers. When someone calls and all your agents are busy, the caller hears hold music and waits until an agent becomes available. Queues are essential for support teams, sales teams, and any group that handles incoming calls.

Queue strategies

The strategy determines how Astradial picks which agent to ring:

​

Edit queue settings

Click the three-dot menu on any queue and select Edit to open the full settings dialog:

​

Basic settings

• Name and Extension — Change the queue’s identity
• Strategy — Change how calls are distributed
• Ring Timeout — How many seconds to ring agents before giving up (default: 15)
• Max Wait — Maximum seconds a caller will wait in the queue (default: 45)
• Status — Active, Inactive, or Paused

​

​

Music on hold

Choose what callers hear while waiting:

• Default — The system’s built-in hold music

​

​
