Security & hardening
- IP-authenticated trunks
- Balance and concurrency ceilings
- Fraud monitoring on outbound
DIDLogic numbering and termination
Wholesale-style DID coverage and termination, sized around channels and balance controls to keep international routing predictable.
-
01
Numbering
- DID inventory
- Country coverage
- Channel counts
Channels per DID sized against real inbound concurrency, not the number count.
-
02
Authentication
- IP-authenticated trunks
- SIP endpoints
- Allowed sources
Only your PBX addresses are permitted to send traffic.
-
03
Routing
- Inbound routes
- Termination routes
- Failover carrier
A second carrier retained for critical destinations.
-
04
Controls
- Balance limits
- Concurrency caps
- Fraud monitoring
Hard ceilings so a compromised extension cannot run up unlimited spend.
Frequently asked questions
Why use a wholesale-style provider?
Wide international DID coverage and competitive termination. The trade-off is that more of the configuration and monitoring responsibility sits with you.
How many channels do we need per DID?
From measured peak simultaneous inbound calls on that number, plus headroom. Buying a channel per DID is usually waste.
What is the main risk?
Toll fraud on outbound. Balance ceilings, concurrency caps, destination allow-lists and alerting are non-negotiable.
