Records needed for this question
Trunk orders, committed channel counts and billed capacity units.
How to investigate
Separate purchased capacity from observed peak usage before challenging a quantity.
An illustrative review decision
For a SIP trunk, purchased channel capacity and observed simultaneous calls answer different questions. Capacity reduction requires service-owner review of peak demand and resilience, even when average utilization is low.
What can lead to the wrong conclusion?
Low utilization alone does not make a committed channel charge incorrect.
The result to retain
A capacity-to-contract comparison with optimization requests separated.
