Routing Optimization

LCR balanced against ASR, PDD and AHT per destination. The cheap route on paper is rarely cheap after reconciliation.

The trade-off

LCR is a race to the bottom.

Pure least-cost routing optimises the wrong number. It minimises per-minute cost and maximises the hidden costs, failed calls, complaints, churn, re-routing effort. We weight cost against the metrics that decide whether the route actually works.

ASR
Answer-seizure floor

Below the floor, the route drops out of the dial plan and the next-best path takes over.

PDD
Post-dial delay cap

Above four seconds kills answer rates. We flag routes drifting past two.

AHT
Holding time band

Sudden drops on a stable route usually mean audio quality, not the dial plan.

Cost
Per-minute, one of four

The only number most LCR engines optimise. Ours is one of four. The other three keep it honest.

What we balance

The four-axis scoring, per destination.

01

Per-destination baselines, not global averages

ASR averages across a route sheet hide everything. Pakistan at 38% and France at 60% do not average to 49%. We score each destination independently.

02

Carrier-neutral routing

We route to the path that holds. We do not own the destination network, so we have no incentive to push traffic through a worse path because it is ours.

03

Real-time route testing

Routes do not fail at midnight, they degrade over hours. Continuous test calls catch the drift before customers do.

04

Automatic failover with documented reason codes

When a route fails over, the reason is logged. Routing changes are auditable, not invisible.

Field math

What the cheap route actually costs.

Worked example

10,000 minutes a day to a destination. Cheap route at $0.018, ASR 28%. Premium route at $0.024, ASR 55%.

Cheap route delivers 2,800 answered minutes for $180.

Premium route delivers 5,500 answered minutes for $240.

Cost per answered minute: cheap $0.064, premium $0.044. The premium route is 31% cheaper per outcome.

Field note

“Only a small percentage of customers that experience poor quality or call failures will actually complain and take the time to put in trouble tickets. The silent majority will simply stop using your service.”
