What is Wholesale VoIP?
Wholesale VoIP (Voice over Internet Protocol) is a telecom service where bulk voice traffic is sold to carriers, resellers, and businesses. Unlike retail VoIP, which serves end-users directly, wholesale VoIP allows telecom companies to deliver large-scale voice termination at competitive rates.
This model is ideal for enterprises, call centers, and telecom providers who need to handle thousands of calls simultaneously with cost savings and global reach.
How Does Wholesale VoIP Work?
Wholesale VoIP works by routing calls over the internet through SIP trunks, gateways, and VoIP carriers. Instead of using traditional PSTN networks, it leverages IP-based infrastructure for:
-
Lower call costs
-
Faster global connectivity
-
High scalability for traffic spikes
📊 Process Flow (Simplified):
Enterprise → VoIP Switch → Carrier Routes → Destination Network → End-User
