Telecom & VoIP project
Telecom & VoIP : end-to-end interconnections, fully under control
OZ-Technology designs, deploys and operates complete Telecom & VoIP architectures : from the SIP connection with your operators through to your IPBX, your call centres and your business applications.
Reliability, resilience and real-time visibility are at the heart of the approach : you stay in control of your voice traffic, while reducing costs and improving the experience for your teams and your customers.
What the architecture covers
- Users / agents (offices, remote work, softphones, mobiles)
- IPBX / call centre platform (Asterisk, 3CX, etc.)
- SBC / Session Border Controller (OpenSIPS, Kamailio, …)
- SIP interconnections with one or more operators
- Real-time call monitoring, CDR and alerts
Your Telecom challenges today
Telephony is no longer just a " desk phone " in an office. Between remote work, collaboration tools, call centres and CRM integrations, a poorly designed VoIP architecture quickly leads to :
Unstable call quality
Cut-offs, echo, one-way audio, latency : often linked to poor NAT/RTP handling or overly complex SIP routes.
Lack of visibility
Hard to anticipate problems, analyse CDR or detect fraud without properly collecting and using call data.
Limited scalability
Adding new sites, operators or special numbers becomes a headache, with scattered and poorly documented configurations.
Security & compliance
Risk of fraud, number spoofing or traffic overload without well-designed safeguards or consumption caps.
What OZ-Technology puts in place
With more than 25 years of experience in telecom and VoIP, OZ-Technology supports you across the entire technical chain :
- Designing SIP architectures and deploying SBCs (OpenSIPS, Kamailio…)
- Multi-operator interconnections, geographic and special numbers
- Integration with your IPBX / call centre platforms
- Intelligent routing, channel limiting, fraud protection
- Collection and analysis of CDR for billing, reporting or optimisation
- Real-time monitoring, proactive alerts and tailor-made dashboards
The goal : simplify what is often complex infrastructure, while giving you concrete tools to manage your traffic and your costs.
Examples of assignments
- Setting up a central SBC to aggregate several SIP operators
- Migrating a traditional PABX to a full SIP VoIP solution
- Creating a secure trunk for an outsourced call centre
- Implementing consumption caps and anti-fraud alerts
- Integrating voice into a broader strategy (IT, energy, cloud)
This Telecom & VoIP project also connects with other OZ-Technology building blocks, for example monitoring or energy optimisation via the Fluxi HEMS project.
