What actually drives per-minute pricing on a wholesale voice rate deck, how origination and termination differ, and what to push back on before signing.
Persistent dead air on an outbound dialer is almost always a termination-route problem, not a bad list. How to tell the difference and prove it in your own CDRs.
A buyer's checklist for choosing SIP termination for an outbound dialer: the ASR, ACD, and PDD benchmarks to demand, the CPS games carriers play, and the red flags.
