PortaOne starts every migration with a Discovery phase. A business analyst and migration engineer analyze the service provider’s requirements, existing documentation, and business flows, define what will and won’t be migrated, and identify any gaps. Together with the service provider, PortaOne prioritizes and estimates the high-priority items. The service provider then receives a “Scope of Work” document and timeline before anything progresses.
Direct access to the legacy software platform’s database is not mandatory. If the legacy vendor restricts data exports, PortaOne can work with standard-format files exported by the service provider from their system, and map data from that legacy system to PortaSwitch. If the legacy format requires adaptation or out-of-the-box tools do not fully cover mapping data, PortaOne engineers write custom migration scripts to handle the translation. If a feature the service provider relies on doesn’t exist in PortaSwitch yet, the development team can implement it in upcoming releases.
PortaOne can manage the migration process end-to-end, coordinating planning, data preparation, execution, and post-migration support.
Two migration strategies are available: run both systems in parallel and switch to PortaSwitch once migration is complete, or move everything in a single planned operation.
PortaSwitch is built on a multi-site architecture comprising a main site and secondary sites in separate locations. Each secondary site continuously replicates data from the main site, so it always has the latest customer and service data.
Traffic distribution between sites is managed by the Dispatching Session Border Controller (DSBC). If the main site becomes unavailable due to a power outage, network failure, or a natural disaster, the DSBC automatically redirects all incoming SIP traffic and device registrations to the secondary site, which switches into stand-alone mode, all without any manual intervention. Customers can continue making and receiving calls, and their balances are tracked accurately during the outage. Once the main site comes back online, the DSBC redirects traffic back to it, and all accumulated changes are synced automatically.
PortaSwitch handles authorization and charging in real time through its billing engine, PortaBilling. When a customer dials a number, PortaBilling authenticates the caller, checks their available balance, and authorizes the call before it connects. If the balance runs out mid-call, the call is disconnected.
PortaBilling prevents overdrafts through fund locking. For every call, the system locks a portion of the customer’s balance to cover the next call interval (e.g., the next five minutes of a call). Those funds are unavailable for any other concurrent session. As the call progresses, the system re-authorizes and locks funds for the next interval. The same mechanism applies to shared service quotas. If several users share a pool of minutes, for example, a “Family” package where all minutes are shared between the customer’s family member accounts , PortaBilling locks a portion of that quota for each active call, preventing users from exceeding the shared limit.
PortaSwitch supports two deployment options: on-premises, where the platform is installed on the service provider’s own hardware, and cloud, where the platform is hosted and managed by PortaOne in an Oracle Cloud Infrastructure data center.
Two commercial models are available, depending on the deployment option chosen.
The unlimited license pricing is based on a per-installation model, defined by a predefined maximum number of physical servers. It does not depend on the number of subscribers, concurrent calls, or any other usage-based metric. This model is available for on-premises deployments only and also includes a complimentary period of 24/7 technical support with access to all feature updates, full source code, database schema, and REST API.
The SaaS subscription (pay-as-you-go) is a monthly fee based on the number of xDRs (billable events such as calls, messages, subscriptions, data sessions, and reseller charges) processed each month. No license purchase is required. This model is available for both on-premises and cloud deployments.
Both models include initial system setup and customized online training.
Billing migrations are rarely straightforward. For Cgates, Lithuania’s second-largest triple-play provider, it took six years, over 20 features and integrations developed by PortaOne, and two mid-project ISP acquisitions. On June 30, 2026, they migrated the last of their 100,000+ subscribers. Here’s how they did it.
