VOS3000 and Sippy are both used by wholesale VoIP carriers to route, rate and bill call traffic. Both work well; the better fit depends on your team and business model.
VOS3000
- Very popular in wholesale and routing businesses.
- Web-based management with flexible routing and rating.
- Typically a lower cost of entry.
Sippy Softswitch
- Class 4/5 capabilities with multi-tenancy.
- Prepaid and postpaid billing with real-time CDR monitoring.
- Dynamic least-cost routing and an API for automation.
Cloud or dedicated?
Small and starting carriers can run well on a cloud (KVM) server. As concurrent calls and calls-per-second grow, move to a dedicated server for consistent CPU and disk performance. Use our VoIP bandwidth calculator to estimate the network you need.
