What is a VOS server?
A VOS or VoIP switch server is a softswitch platform used to manage SIP accounts, customer balances, rate tables, routing rules, billing, reseller access, gateways and call detail records. It is used by VoIP wholesalers, resellers and service providers rather than by a single business making calls.
Do I need a dedicated server or a hosted account?
A dedicated switch is for customers who need to manage their own carriers, routes, customers, balances and billing — typically resellers and route providers. A business that only needs to make calls is better served by a hosted SIP account, without the security, backup and monitoring burden of running a switch.
Is installation the same as ongoing management?
No. Installation places and configures the platform. Ongoing management covers monitoring, security patching, routing changes, backups, log review, fraud controls, troubleshooting and performance tuning. The contract should state explicitly which tasks are included after delivery.
Can a VOS server support resellers and sub-accounts?
Most carrier-grade switch platforms can create customers, resellers, sub-resellers, rate plans, credit limits and separate portal logins. The exact hierarchy depends on the software edition, licence and deployment design.
Can you migrate an existing switch?
Yes. Migration covers exporting configuration, rate tables, customer records and CDR history, running the new platform in parallel for verification, then cutting over with a tested rollback plan.
What should be tested before final payment?
Account creation, billing accuracy, rate matching, origination, termination, caller ID behaviour, failover, CDR accuracy, concurrent-call and CPS limits, backup restoration, and administrative access. Keep a written configuration record and an emergency contact process.
