What is wholesale VoIP termination?

Wholesale VoIP termination is the service that connects a VoIP call through carrier networks to the destination number. Softtop delivers A-Z termination across 180+ countries on direct Tier-1 interconnects with rates from $0.003/min.

What ASR can I expect on Softtop wholesale routes?

Softtop CLI routes deliver 60%+ ASR (Answer Seizure Ratio) on major destinations. Route quality is monitored 24/7 by the NOC with automatic least-cost routing adjustments to maintain performance.

What is the difference between CLI and Non-CLI routes?

CLI routes preserve the original caller ID all the way to the destination — required for business outbound calls in most countries. Non-CLI routes are cheaper but strip or alter the originating caller ID.

How does least-cost routing (LCR) work?

Softtop's LCR engine automatically selects the lowest-cost route that meets your quality thresholds for each destination, maximizing cost savings without sacrificing ASR or voice quality.

How is billing structured?

Billing is per-minute with 1-second increments and no minimum call duration. Monthly invoices are generated automatically, or prepaid credit can be loaded via the self-service portal.

How do I get started with wholesale VoIP?

Submit the wholesale inquiry form or contact the wholesale team. A custom A-Z rate sheet and SIP credentials are typically provided within one business day of qualification.
