Outbound calls are the backbone of business communication, and choosing a reliable VoIP termination service determines whether your conversations are clear, cost-efficient, and trusted by customers. As a SMB-focused VoIP provider, Bongs ensures high-quality connections, secure routing, and global coverage so every outbound call strengthens brand reputation.
What is VoIP Termination?
VoIP termination is the process of routing an outbound call from an internet-based VoIP network to the public switched telephone network (PSTN) so the recipient can answer on a landline or mobile phone.
In semantic terms, the Entity is VoIP Termination, the Attribute is process of ending the call beyond the VoIP system, and the Value is outbound routing through carriers. This service connects digital VoIP infrastructure with traditional telephony, ensuring reliable call delivery, stable caller ID reputation, and optimized costs for businesses.
How Does VoIP Termination Work?
VoIP termination works by converting a digital VoIP signal into a standard phone call and routing it through carrier interconnects until it reaches the recipient’s mobile or landline.
The process follows a step-by-step flow:
- Call Signaling – Session Initiation Protocol (SIP) establishes the call request between VoIP systems and the carrier.
- Routing – The call is directed through least-cost or quality-based routes chosen by the provider’s intelligent routing engine.
- Interconnects – Connections with Tier-1 and Tier-2 carriers allow the call to leave the VoIP network and enter the global PSTN.
- Termination Delivery – The call reaches the recipient via the local carrier’s switching infrastructure.
Quality is measured by key metrics:
- ASR (Answer Seizure Ratio): % of successfully connected calls (average reliable networks score 60–70%).
- ACD (Average Call Duration): Reflects call stability and user satisfaction (healthy ACD = 2–4 minutes in call centers).
- Jitter & Latency: Variations above 30 ms jitter or 150 ms latency reduce audio quality.
VoIP Origination vs Termination: Key Difference
VoIP origination refers to inbound calling (receiving calls from PSTN into a VoIP network), while VoIP termination refers to outbound calling (routing VoIP calls to landlines or mobiles on PSTN).
- Origination Use Case: Businesses purchase DID or toll-free numbers so customers can call them via PSTN, which then delivers the call into their VoIP system.
- Termination Use Case: Companies use termination to place outbound calls from their VoIP system, routed through carriers, reaching recipients worldwide.
Together, origination ensures customers can reach the business, and termination ensures the business can reach customers, forming the two-way communication backbone of any SMB VoIP phone system.
Types of VoIP Termination Services (Wholesale, Retail, A-Z)
VoIP termination services fall into three main categories: wholesale, retail, and A-Z routing. Each serves a different business need, with unique billing models, advantages, and trade-offs.

Choosing the Right VoIP Termination Provider
To choose the right VoIP termination provider, evaluate five key factors: quality routes, global coverage, customer support, pricing, and fraud protection.
Checklist for SMBs
- Quality Routes: Look for direct Tier-1 carrier connections for stable call delivery.
- Global Coverage: Ensure A-Z routing that reaches 180+ countries under one contract.
- Customer Support: 24/7 availability with human support, not ticket-only systems.
- Pricing: Transparent per-minute or bundled rates; avoid hidden UCaaS fees.
- Fraud Protection: Real-time monitoring for SIP attacks, call spoofing, and toll fraud.
Why This Matters
Unlike large UCaaS providers (RingCentral, Zoom, Nextiva) that sell feature-bloated suites, SMB-focused providers like contactivity.io deliver only what matters: reliable routes, predictable costs, and personal support. This focused approach prevents “solution fatigue” while ensuring business-critical calls remain professional and affordable.

VoIP termination rates vary by region: UK routes typically cost £0.005–£0.01 per minute, while US routes average $0.004–$0.008. Many providers now offer per-second billing for fairness, with pricing differences between CLI (caller ID shown) vs. Non-CLI routes.
Example Rates (Competitor Benchmarks)
| Region | CLI Rate (per min) | Non-CLI Rate (per min) | Billing Type | Notes |
| UK | £0.007 | £0.005 | Per-second | CLI ensures higher answer rates |
| US | $0.006 | $0.004 | Per-minute | Non-CLI often cheaper, less trusted |
(Sample averages from leading competitor rate sheets; actual rates vary by carrier and volume.)
CLI vs Non-CLI Explained
- CLI (Calling Line Identification): Displays caller ID, improves trust and answer rates, slightly higher cost.
- Non-CLI: Cheaper, but often flagged as spam or ignored by recipients.
Why Billing Models Matter
- Per-second billing is cost-efficient for short-duration calls, common in call centers.
- Per-minute billing can inflate costs for SMBs with high call volumes.
Security & Fraud Prevention in VoIP Termination
Secure VoIP termination depends on fraud monitoring, STIR/SHAKEN compliance, and CLI masking, which together protect caller ID reputation and reduce risks of spoofing and toll fraud.
Fraud Monitoring
Top providers deploy real-time anomaly detection, traffic pattern analysis, and IP blocking to stop toll fraud, account takeovers, and call pumping. Continuous monitoring ensures that suspicious spikes in call volume are flagged instantly.
STIR/SHAKEN Protocols
The STIR/SHAKEN framework verifies caller identity across networks, preventing caller ID spoofing. For SMBs, this improves trust and keeps outbound calls from being marked as spam.
CLI Masking
Caller Line Identification (CLI) masking hides or replaces sensitive numbers while still displaying a verified ID. It balances privacy with trust, especially for remote teams and outbound call centers.
Bongs & Trusted Caller ID
Where competitors often focus only on low-cost routes, Bongs adds a “trusted caller ID reputation” layer, combining STIR/SHAKEN compliance, redundant fraud monitoring, and premium CLI routes. This gives SMBs enterprise-level protection without UCaaS complexity.
