FreeSWITCH
Custom FreeSWITCH Development
Scaling FreeSWITCH requires more than standard configuration. We build carrier-grade voice platforms with the custom switching paths, call routing logic, and high-availability architecture your infrastructure needs to perform under the most demanding traffic loads, delivered production-ready.
What We Build
Custom FreeSWITCH environments for high call volumes and complex flows, providing stable, extensible platforms built around your business logic.
Custom Call Routing
Route every call exactly where it needs to go, with dialplan logic covering least-cost routing, time-based routing, geographic routing, and failover strategies tailored to your traffic patterns.
Enterprise Security
Protect your voice infrastructure from toll fraud and unauthorised access through TLS/SRTP encryption, custom ACL enforcement, and fraud detection layers.
Multi-Tenant Support
Run multiple clients or business units on a single platform, with domain-separated environments, per-tenant routing, dedicated resources, and billing isolation.
Extensible Integration
Connect FreeSWITCH to your CRM, billing platform, or custom backend through Event Socket Layer bindings, REST API hooks, and mod_xml_curl, without touching core telephony logic.
Media Processing
Process audio natively within FreeSWITCH, with transcoding, mixing, recording, TTS, STT, and early media handling built into the platform.
High Availability
Zero-downtime deployments backed by active-active and active-passive clustering, automatic failover, database replication, and geographic redundancy.
Use Cases
The same FreeSWITCH platform, configured to the demands of very different operations and industries.
IVR Systems
Businesses handling high call volumes build multi-level IVR systems that route callers intelligently, reduce agent load, and integrate directly with your CRM or database.
Conferencing Platforms
Teams and platforms needing reliable multi-party audio or video run conferencing infrastructure that scales to hundreds of concurrent participants without third-party dependencies.
Class 4/5 Softswitch
A switching core built to your exact commercial model, with CDR generation, rate management, and interconnect billing for wholesale and carrier-grade voice traffic.
Contact Centers
Full ownership of your contact center stack, with ACD, skills-based routing, and queue management built to your operations, not a vendor's pricing model.
Wholesale VoIP
Carriers and wholesale providers handle large traffic volumes with LCR, rate deck management, and real-time billing tailored to their network.
Unified Communications
A single platform combining voice, video, messaging, and presence, with SIP trunk and WebRTC integration built in and no third-party dependencies.
