STIR/SHAKEN Attestation Levels
STIR/SHAKEN defines three attestation levels carriers apply to outbound calls. Level A is full attestation: the caller is verified and the number ownership is confirmed. Level B is partial attestation: the caller is verified but number ownership cannot be confirmed.
Level C is gateway attestation: the call only passed through a known gateway.
On US networks, A-attested calls show measurably higher ASR than B or C calls. Many terminating carriers downrank B and C traffic during analytics-driven labelling.
Wholesale providers that can issue A-level attestation on owned numbers protect outbound campaigns from spam-likely labels. Twiching maintains its own SHAKEN certificates and signs A-attested traffic at the originating edge.
Outside the US, the equivalent frameworks are evolving. France enforces a similar STIR/SHAKEN regime since October 2024. The UK requires originating-CLI verification under Ofcom General Condition C6.
Canada's STIR/SHAKEN deployment is enforced by the CRTC. International calls cannot inherit attestation across networks. They drop back to gateway attestation unless both endpoints share a certificate trust chain.
Direct Routes vs Aggregated Routes
A direct route is a single hop from your provider to the in-country terminating carrier. An aggregated route passes through one or more intermediate brokers.
Each broker adds ~10-30 ms of PDD and one more failure point. Direct routes typically carry an ASR 3-6 points higher than aggregated routes to the same destination.
Premium tier decks list only direct routes. Standard decks blend direct and aggregated paths to lower the per-minute rate.
Economy decks are aggregated-only and best reserved for non-critical traffic such as notifications or marketing dialers. Confirm route type per destination before signing — most providers disclose this on request.
The Advantages of SIP Trunking
SIP trunking offers cost savings, scalability, and improved reliability. With SIP trunking, businesses consolidate voice and data services over a single internet connection.
Significant cost savings follow compared to traditional phone systems. https://youtu.be/M4GUtsACBHY?si=-zOEKuQ_iofKP_0s
By eliminating physical phone lines, businesses reduce monthly expenses. Line rentals, long-distance charges, and maintenance costs all drop. SIP trunking lets businesses add or remove channels as needed, adapting to changing communication requirements.
Redundant connections and failover options ensure continuous communication. Network outages won't interrupt service. By partnering with a trusted wholesale VoIP provider like Twiching, businesses enjoy SIP trunking benefits and reliable communication.
Codec Selection and Bandwidth Planning
Codec choice determines voice quality and bandwidth per concurrent call. G.711 uses ~85 kbps per call and offers PSTN-grade clarity. G.729 compresses to ~30 kbps with audible quality loss on music or background noise.
Opus negotiates between ~6 and 510 kbps and is the default for WebRTC interconnects. Wholesale termination typically defaults to G.711 with transcoding available on request.
Plan inbound bandwidth at peak concurrent calls multiplied by codec rate, plus 20% headroom. A 200-seat contact centre on G.711 needs roughly 20 Mbps symmetric for voice alone. Mixed codecs require a transcoding fee per minute, typically $0.0005-$0.001, that should be itemised in the rate sheet rather than buried in a blended rate.
Choosing the Right Wholesale VoIP Provider
When selecting a wholesale VoIP provider, consider reliability, pricing, features, and customer support. Here's why Twiching stands out:

Fraud Controls in Wholesale VoIP
IRSF (International Revenue Share Fraud) typically targets premium-rate destinations in fewer than five countries at any given time. A compromised SIP trunk can ring up six-figure exposure in under an hour without real-time spend caps. The standard mitigations are destination allow-lists, per-trunk concurrent-call limits, and velocity rules that trip on more than 50 attempts per minute to a single prefix.
Twiching applies a default daily spend cap on new trunks. Premium destinations such as Cuba, Latvia mobile, and selected Pacific islands are blocked unless explicitly opted in.
Anomaly alerts fire within 60 seconds of unusual call patterns. The trunk is auto-suspended if confirmed fraud is detected, and replay logs are preserved for forensic review.
Selecting the best wholesale VoIP provider for your operation requires matching provider capabilities to your specific traffic profile. A provider optimised for high-volume US domestic termination may not be the best choice for international A-Z traffic.
The best providers offer granular routing control — the ability to assign specific carriers to specific destination ranges. That lets you optimise for cost on commodity routes while prioritising quality on business-critical destinations.
Portability matters as much as current performance. The best wholesale VoIP providers make it easy to port away if their service degrades. Review contract termination clauses: excessive notice periods, early termination fees, or restrictions on porting numbers away are contractual traps.
A provider confident in their quality will offer flexible exit terms because they know you will stay.
