OVOO SLEE

Drop-in, modern replacement for JAIN SLEE / Rhino. Same service model (SBB/RA/Activities), modern toolchain, and a simple migration path. No risky rewrites.

Carrier-gradeSub-ms handlersHorizontally scalable

Rhino / JAIN SLEE replacement.

If you run services on Rhino®/JAIN SLEE, our SLEE executes the same SBB → RA → Activity/Timer pattern. Move in layers: compatible adaptors first, then gradually modernize. No “big-bang” switch.

  • • Compatible SBB/RA/Profiles model + config converters
  • • Adaptor shim for SIP/SS7/SMPP/HTTP — faster bring-up
  • • Parallel modes (shadow/canary) for safe cutover
  • • Migration tooling + test harness + rich tracing

Key features

Everything you need to migrate quickly and grow safely.

SBB/RA compatible

Same composition model; profiles, activities and timers.

Ready-made adaptors

SIP, SS7/CAP/INAP, SMPP, HTTP/REST, DB with back-pressure & retry.

HA & continuity

Clustering, failover, session recovery and graceful degradation.

Observability built-in

Tracing, metrics and SLIs with SRE-ready dashboards & alerts.

Developer experience

Hot-reload loops, test harness, synthetic traffic, chaos hooks.

Cloud-native ops

Containers, IaC, blue/green, GitOps. Zero-downtime upgrades.

Security & Compliance – benefits

We design and operate SLEE in line with NIST CSF 2.0 and the EU NIS2 directive for key and important entities.

Govern icon

Govern & accountability

Policies, ownership and management oversight mapped to CSF Govern.

Assets icon

Identify assets & risk

Service inventories, data classification and supplier risk (CSF Identify).

Protect icon

Protect: access & encryption

Least-privilege, SSO, secrets/KMS, hardening and patching (CSF Protect).

Detect icon

Detect: monitoring & alerts

Telemetry and anomaly detection with alert runbooks (CSF Detect).

Respond icon

Respond quickly

Playbooks, communications and containment mapped to CSF Respond; supports 24h/72h reporting windows.

Recover icon

Recover & continuity

Backups, DR drills and continuity plans aligned with CSF Recover.

NIS2 highlights: supply-chain risk management, incident notifications (preliminary 24h / detailed 72h), technical safeguards (access control, encryption, patch management), management accountability, and administrative fines (up to €10M or 2% of global turnover).

Migration made easy

Move from Rhino/JAIN SLEE with no downtime and controlled risk.

1) Plug-compatible RAs & shims

Compatibility layer for SIP/SS7/SMPP/HTTP/DB. Run existing flows and replace components gradually.

  • • Config & parameter mapping
  • • Profile & timer converters
  • Shadow (traffic mirroring) + canary

2) Zero-downtime cutover

Blue/green, SLO guardrails and automatic rollback. Metrics aligned with your observability stack.

  • • RA and SBB health-checks
  • • Event replay/compensations
  • • SRE runbook & cutover checklists
