Telco integration, done by people who ship it
The tools on this site come from real integration work. When a paste turns into a rabbit hole, these are the engagements that get you out.
SMPP Integration
We connect ESMEs to SMSCs and aggregators end to end: bind setup, DLR flow, throttling and windowing, encoding and concatenation, and the interop quirks that eat weeks. Fixed-scope packages from first bind to production traffic.
- SMSC / aggregator SMPP hookups
- DLR and message-state handling
- Throughput / window tuning
- Encoding & concatenation correctness
SMSC / STP / Sigtran Consulting
SMSC, STP, MAP, SCCP GT routing and Sigtran (M3UA/SUA) work — the retiring-skillset niche where networks still run the protocol daily. Senior-boutique engagements for operators and vendors.
- SMSC / STP configuration and troubleshooting
- SS7 / Sigtran (M3UA, SCCP, TCAP, MAP)
- E.214 global-title routing
- HLR / MNP integration
WebRTC & Dialer Development
Browser dialers, click-to-call, voice bots and AI-voice integrations — built by engineers who also speak SS7 and SMPP, so the media path and the signalling both hold up in production.
- Custom WebRTC dialers & softphones
- WebRTC ↔ SIP gateways
- AI voice / transcription integrations
- Voice bots and IVR
USSD Gateway Development
USSD applications and gateway integration with the network side handled: MAP dialogue, session model, timeout behaviour and the 182-character reality. Project-based, with a Brazil/PT angle for local carriers and VAS.
- USSD application development
- Gateway integration (SMPP-fronted)
- Session and timeout design
- Menu design under GSM-7 limits
