# What Are Wholesale VoIP Routes?
Wholesale VoIP routes are large-scale voice traffic pathways that telecom carriers use to exchange telephone calls across national and international networks. Instead of delivering calls directly to end users, wholesale providers sell voice termination services to other carriers, resellers, contact centers, call service providers, and enterprise communication platforms.
Each route represents a connection to a specific destination, country, mobile operator, or local network. These routes enable providers to terminate voice calls efficiently while balancing cost, quality, and network reliability.
For example, if a customer in Canada calls someone in Brazil, the originating copyright may purchase a wholesale VoIP route from another provider that specializes in South American call termination.

# How Wholesale VoIP Routing Works
Wholesale VoIP routing involves several interconnected components that work together to ensure successful call delivery.
The process generally follows these steps:
1. A customer initiates a phone call.
2. The originating copyright converts the voice into digital packets.
3. A softswitch analyzes routing tables.
4. The Least Cost Routing (LCR) engine selects the optimal path.
5. The selected wholesale copyright receives the call.
6. The destination copyright terminates the call.
7. The recipient answers the call.
Throughout this process, multiple wholesale providers may participate depending on pricing agreements and network availability.
