Wholesale Voice: get started and use it well
Connect your switch for voice termination: what we need, how to test, and how to keep quality high.
Wholesale Voice gives carriers and resellers voice termination with direct and premium routes, automatic failover and real-time call records.
What we need from you
- Your company details and expected traffic (countries and volume).
- Your signalling IP addresses, so we can allow them.
- The number format you send (we recommend full international format).
- Codecs you support.
Getting connected
- We agree a rate sheet and open a prepaid account.
- We allow your IP addresses and send connection details.
- Run a test route with a small set of calls.
- Check call quality, caller ID and billing, then add traffic step by step.
Best practice
- Send full international numbers.
- Send a valid caller ID. Many destinations reject calls without one.
- Ramp up slowly. Increase traffic in stages and watch the figures.
- Keep your balance topped up, or use online top-up, so calls do not stop.
- Report problems with examples: number, time, and call ID.
Quality figures to watch
| Figure | What it means |
|---|---|
| ASR | Share of calls that are answered |
| ACD | Average call length; a sudden drop signals a problem |
| PDD | Delay before ringing |
Advanced options
Ask us about these:

Calls are rejected. Check that your IP address is allowed, the number format is correct, and your balance is sufficient.
One destination has a poor answer rate. Send us examples and we check the route.
