Advanced Call Centre Features: Queues, SLA Monitoring, Wallboards
Managing high call volumes can overwhelm teams and frustrate customers. Yeastar’s advanced call centre tools provide queues that organise incoming calls efficiently, ensuring no caller waits too long.
SLA monitoring tracks service levels in real time, helping managers keep targets and quickly address bottlenecks. Wallboards display live performance stats for agents, boosting motivation and transparency.
This helps your call centre by:
