Introduction to VoIP Wholesale Termination
VoIP Wholesale Termination refers to the backend carriers and providers that enable these VoIP calls to connect. When a business gets a VoIP phone system, it connects to a VoIP service provider. This provider needs a way to bridge the calls to landline and mobile networks. VoIP Wholesale Termination providers offer this connectivity.
Wholesale carriers have access to VoIP routes across the world. They partner with local VoIP providers in different countries and create interconnect agreements. This allows them to terminate VoIP calls on the public phone network globally. Businesses can leverage VoIP termination to expand their communication reach.
Voice over Internet Protocol (VoIP) has revolutionized business communications over the last decade. VoIP uses the internet to make voice calls instead of traditional wired telephone networks like the Public Switched Telephone Network (PSTN). Companies can save substantial costs on long distance calls and benefit from unified communications by adopting VoIP solutions.
How VoIP Wholesale Termination Works
VoIP Wholesale involves large carriers purchasing VoIP minutes and channels from smaller providers. They bundle these services to offer global connectivity. Here are the key steps in a VoIP Wholesale Termination setup:
- Businesses get VoIP PBX systems and subscribe to a VoIP phone service. This can be an on-premise system or cloud-based.
- The VoIP provider connects the business systems to their Voice over IP gateways. These gateways convert VoIP calls to other protocols like SIP, RTP, etc.
- For local call termination, the VoIP provider can directly connect the gateways to local telcos and ISPs.
- For international call termination, the provider partners with wholesale carriers.
- Wholesale carriers use least cost routing and quality algorithms to pick the optimal networks. Calls are terminated via local VoIP partners.
- Wholesale carriers convert the VoIP calls back to standard protocols for connecting with landlines, mobiles, etc.
This interconnection between the VoIP provider, wholesale carrier, and local VoIP partners enables seamless call completion.
Benefits of VoIP Wholesale Termination
VoIP Wholesale Termination offers multiple advantages for businesses compared to traditional telephony:
Cost-Effectiveness: Wholesale VoIP rates are much lower than ISDN and PSTN calls. Businesses can save 60% or more per minute on international calls.
Scalability: The VoIP network can be scaled instantly to support more concurrent calls. No hardware upgrades needed.
Global Reach: VoIP termination providers have partnerships worldwide for local call access globally.
Quality of Service: Wholesale carriers provide quality guarantees on key parameters like jitter, latency, packet loss etc.
Redundancy: There are failover mechanisms in case any particular route has issues.
Flexibility: Businesses can easily add, remove or modify call routing logic as needed.
Billing Options: Wholesale VoIP allows pre-paid or post-paid billing models. Call bursts can be easily handled.
VoIP Termination Wholesale Business Models
|Minutes Aggregator||Buys VoIP minutes in bulk from smaller carriers and terminates calls|
|White Label Wholesaler||Sells managed VoIP services to resellers under partner brand|
|International Gateway||Interconnects domestic VoIP networks with global destinations|
|Direct Termination||Large carrier terminates calls on its own network end-to-end|
Key Players in the Wholesale VoIP Industry
The VoIP Wholesale Termination ecosystem has carriers of all sizes providing services:
Tier 1 Carriers
These are large incumbent carriers like AT&T, Verizon, CenturyLink etc. They have their own extensive networks and provide nationwide VoIP services.
Tier 2 Carriers
These are smaller regional operators like Bandwidth, Intelepeer, Net2Phone etc. They aggregate routes and buy excess capacity from Tier 1 carriers.
Tier 3 Carriers
These are small prepaid VoIP carriers and calling card providers. They buy wholesale minutes from Tier 1 and Tier 2 carriers.
Aggregators like Inteliquent connect various tier 1, 2, and 3 carriers. This improves reach and redundancy.
Resellers purchase VoIP services wholesale and sell under their own brand to businesses. This lets small businesses access good quality VoIP call services.
VoIP Termination Quality Standards:
|Jitter||Less than 30 ms||99.99%|
|Latency||Under 150 ms||99.99%|
|Packet Loss||Below 1%||99.999%|
|Network Uptime||Greater than 99.999%||Financial penalties for violations|
VoIP Call Routing and Traffic Management
Wholesale VoIP providers use intelligent call routing and traffic management to ensure quality:
Least Cost Routing (LCR): LCR algorithms pick the most cost-effective route that meets the minimum quality for each call. This reduces costs.
Quality-Based Routing: Real-time traffic monitoring is used to route calls through least congested networks. This maintains quality.
Load Balancing: Calls are distributed across providers and routes to avoid overloading any specific path.
Failover Mechanisms: If a certain provider has an outage, calls are instantly routed through alternate connections.
Traffic Analysis: Historic traffic patterns are analyzed to plan capacity and optimize routing logic.
Regional Regulations on VoIP Services:
|United States||Largely unregulated except for compliance mandates|
|European Union||Light regulation, must enable emergency calling|
|China||Restricted, only 3 state-owned operators allowed|
|Middle East||Blocks VoIP calls made outside state-sanctioned providers|
|India||No restrictions on VoIP domestic calls, international regulated|
Challenges and Solutions in Wholesale Voice Termination
Some key challenges faced in wholesale Voice termination include:
Call Quality Issues: Jitter, latency, packet loss can cause choppy audio. Wholesale carriers maintain high QoS standards and SLA guarantees to address this.
DTMF Interoperability: Touch-tone signals can get distorted. Carriers use mechanisms like RFC 2833 for reliable transport.
Fraud Management: Hackers exploit networks to make unauthorized calls. Carriers implement security protocols like SIP-TLS, SRTP, firewalls etc.
Regulatory Compliance: Different countries have specific regulations that need compliance. Carriers ensure they meet all legal obligations.
Regulatory Compliance in Wholesale call Termination
The US Federal Communications Commission (FCC) provides guidance on VoIP telephony services. Wholesale carriers ensure compliance on key aspects:
- Disability Access: Support for relay services.
- E911 Service: Support for emergency calls including location data.
- CALEA: Capability for lawful interception by law enforcement.
- Privacy: Protection of customer information.
Many countries allow unrestricted VoIP services while some impose restrictions. Wholesale carriers comply with all country-specific regulations on VoIP termination.
Choosing the Right Wholesale VoIP Provider
Businesses should evaluate wholesale carriers on these key aspects:
Network Coverage: Look for global direct connectivity or partnerships with top-quality local VoIP providers.
Pricing Models: Compare per minute rates, monthly access costs, and termination fees.
Quality of Service: Ensure QoS guarantees as per industry standards for latency, jitter, packet loss.
Customer Support: Look for 24/7 technical support and quick resolution of issues.
Service Reliability: Check for proven uptime record and redundancy mechanisms.
Security: Vendor should have facilities to detect fraud patterns and prevent abuse.
