How to choose a wholesale VoIP provider
Short answer: pick the carrier that delivers your caller ID on the destinations you actually call, bills in small increments, and lets you test with a small prepaid balance before you commit. Below is the checklist we recommend, and how VoxioTelecom compares with a typical traditional carrier.
The 6-point checklist
- CLI quality — does your caller ID arrive intact on each target country?
- Billing increment — per-second or 6/6 versus 60/60 rounding.
- ASR / ACD — real answer rates and call durations on your traffic.
- Onboarding speed — can you get a live test trunk today?
- Payment and terms — prepaid, crypto, no minimum commitment.
- Visibility — real-time CDRs and an API for your own reporting.

Frequently asked questions
What is the best wholesale VoIP provider?
The best provider depends on your traffic: check CLI quality on your target destinations, billing increments, ASR/ACD, payment flexibility and how fast you can get a test trunk. VoxioTelecom is built for teams that want Premium CLI routes, prepaid crypto or card payment and a trunk live in about 60 seconds.
How do I test a wholesale VoIP route before committing?
Open a prepaid account, add a small balance, and place controlled test calls to numbers you own. Compare CLI delivery, post-dial delay and audio on each destination before sending production traffic.
Which wholesale VoIP providers accept crypto?
VoxioTelecom accepts Bitcoin, USDT (TRC-20 and ERC-20) and Ethereum for prepaid SIP trunking, credited automatically after on-chain confirmation.
Why does per-second billing matter?
With 60/60 rounding a 10-second call is billed as a full minute. Per-second or 6/6 billing keeps cost aligned with real usage, especially for short-call traffic.
