What is wholesale VoIP?
Wholesale VoIP is the supply of voice connectivity in bulk to other providers (carriers, resellers, ISPs and large businesses) rather than to end users. It covers call termination (routing outbound calls to their destination), origination (inbound numbers) and carrier interconnects, priced per minute or per channel at wholesale rates.
What is voice termination?
Voice (call) termination is the process of routing an outbound call from one network to its destination network so the call can be completed. Wholesale termination providers connect to multiple carriers and route each call over the best available path, balancing cost and quality, commonly described as A-Z termination for global destination coverage.
