# Blureon Telecom — documentation for AI agents and engineers Blureon Telecom is an ANCOM-licensed telecommunications operator with its own network and datacenter in Cluj-Napoca, Romania. It provides SIP trunking, geographic and national numbers, number porting and GSM SIM hosting, alongside its own multi-tenant PBX platform, hosted or on-premise. The company's registered name is Blureon SRL. Its software products are the Blureon PBX phone system and the Blureon Phone calling app. ## Status, as of 5 November 2026 - Blureon Phone: available for macOS and Windows; the Free package costs nothing, for companies and organisations (nothing Blureon offers is for private individuals).

The AI features are built, but not yet tested with a real AI provider. Test systems are demo accounts on Blureon's phone system, set up on request for 14 days (at most 90); they receive calls on the shared demo number, after a 4-digit code, and their only outgoing calls are to 112. The first customers join through an early access programme. The Blureon cloud version: in preparation. - Operator services (SIP trunk, numbers and DID, minutes, number porting): expected January 2027. - GSM SIM hosting: live, sold now, in early access, to Blureon PBX customers. - Current packages and prices (public JSON, the single source): https://portal.blureon.com/api/catalog/blureon-phone and https://portal.blureon.com/api/catalog/blureon-pbx.

Legal details: Blureon SRL, Tax ID (CUI) 49374555, Trade Register J12/74/2024. Provider authorised by ANCOM under general authorisation, type certificate no. eSC2769/10.04.2025. ## Operations and delivery - Delivery model: electronic communications operator with our own infrastructure (data centre in Cluj-Napoca) and our own voice network, with direct interconnections to other operators. - Region: Romania, with room to expand into the EU. - Typical onboarding: (1) technical assessment of the current setup; (2) trunk/number/phone-system configuration; (3) number porting and parallel testing; (4) move to production with monitoring. - Support: engineers who run the infrastructure daily; escalation for incidents. - Responsibilities: Blureon provides routing, numbers, network availability and support; the client provides the internet connection at their premises and configures their own equipment where applicable. - GDPR: traffic data is processed strictly for service delivery and under legal obligations; infrastructure is self-hosted. ## Service: SIP Trunk A SIP trunk that connects a phone system (Asterisk, FreePBX, 3CX, Yeastar, Grandstream, Blureon PBX) to the public telephone network, with channels sized for the client's call volume. Pipeline: 1. The phone system authenticates over SIP, either by registration or by IP address. 2. DID numbers are attached to the trunk and reach the phone system, which passes them on to voice menus, call queues, groups or extensions. 3. The codecs are chosen per trunk, to suit the client's phone system. Standards and protocols: SIP (RFC 3261), SDP, RTP. Edge cases and limitations: quality also depends on the client's internet connection (the last mile), which Blureon does not monitor; without QoS on the last mile, variations can occur. For a standard configuration, activation can be quick; if numbers are being brought over through porting, the porting procedure's timeline is added. Comparison: versus ISDN/analogue lines — scalable, with a cost model that can be a better fit for the client's call volume, and modern features; versus reselling other operators' capacity — Blureon routes the traffic itself, as a licensed operator. ## Service: Landline numbers and DID Real phone numbers from the ranges ANCOM allocated to Blureon: 021 (geographic, Bucharest-Ilfov), 0375 (national) and the short 031 950 x numbers, delivered on the client's SIP trunk. Numbers from other counties: not for now. Pipeline: 1. The number is taken in turn (ordinary numbers, no allocation fee) or chosen from the list (one-off fee; special and short numbers have their own fee, and short numbers a monthly supplement). 2. Allocation to a trunk, with the address where the service is installed, and delivery in the destination header, for internal routing (IVR, queues, extensions). Edge cases and limitations: numbers can be ported under the applicable conditions and procedures, both inbound and outbound; for new numbers, availability and the activation timeline are confirmed after the client's details are verified. Comparison: DID numbers on the same trunk versus separate physical lines per number — DID is more flexible and easier to scale. ## Service: Number porting Moving existing numbers from any operator to Blureon, keeping the same number, under the applicable ANCOM portability procedure. Pipeline: 1. Eligibility validation (active number, no outstanding debts to the donor operator). 2. Preparing the porting request and mandate, signed by the client; submission and coordination with the donor operator. 3. Setting the porting window; pre-configuring routing on the Blureon side and, where possible, running in parallel. 4. Switchover within the agreed window; checking inbound and outbound calls; confirmation. Edge cases and limitations: outstanding debts to the donor operator can block the porting request; the porting window follows the timetable agreed between operators, so it is confirmed after the case is reviewed rather than fixed in advance. Comparison: versus changing your number — the client keeps the same phone identity and does not need to update materials or contacts. ## Service: GSM SIM Hosting Live: sold now, in early access, to Blureon PBX customers. The client's SIM cards are physically hosted in GSM gateways at Blureon and connected to the Blureon PBX phone system as GSM lines. Pipeline: 1. The client sends the SIM cards; they are installed in the GSM gateway. 2. Each SIM becomes a line in the phone system; the mobile number can be routed, recorded and put in queues. 3. Calls to mobile numbers go out over the SIM (using the subscription's minutes). 4. SMS can be sent from the SIM cards, from the phone system. Compatibility: any Romanian mobile operator. Edge cases and limitations: depends on the GSM signal at the gateway's location; subscriptions remain the client's own. ## Product: Blureon PBX A multi-tenant phone system, in alpha, on-premises (the cloud version is in preparation), with built-in AI features. Telephony features, used with real calls on Blureon's test phone system: visual call-flow editor, call queues and ACD (callback from the queue is built, not yet used by a customer), time conditions and public holidays, call recording (with a code the agent presses to pause it while the customer reads out card details), routing with Least Cost Routing and backup routes. Partial: WhatsApp only sends, it does not receive; SMS goes out through the customer's gateway (GSM, SMPP, HTTP); the dialer and campaigns (manual, preview, predictive) are built but not yet proven at a customer. AI features, built but not yet tested with a real AI provider: the configuration agent (generates the call flow from a natural-language description), voice agents, voicemail transcription by email, post-call transcripts, summaries, tone and topics, the topics report. Card numbers are masked automatically in transcripts. The recording or text goes directly from the phone system to the AI provider chosen by the customer (OpenAI, Anthropic, ElevenLabs, Deepgram), with the customer's key; transcription can also run locally; with the voice agent, call audio goes in real time to OpenAI. Blureon receives only the usage (quantity and cost). Not available: semantic search across conversations and natural-language querying of the data. Architecture: each company's data is kept separate in the database, not just in the menu; each company's administrator logs in to the same web interface, sees only their own company and makes the routine changes (users, extensions, numbers, voice menus, schedules, queues), while the companies, licences and phone system settings stay with the phone system's administrator; TLS and SRTP available, off by default, switched on in the web interface; a REST API for the main functions (extensions, numbers, trunks, flows, calls, recordings, queues). Deployment: on-premises (on the client's own server); hosted by Blureon, in preparation; multi-tenant with per-client isolation; white label (the web interface's product name, logo, browser tab icon and main colour, with a brand chosen per customer company; emails sent to users keep the Blureon PBX name for now) included in Enterprise, an add-on on the other paid packages. The Blureon Phone app keeps its name; on Enterprise, on Mac and Windows, it shows the customer company's name and logo. Packages: PBX Free (10 extensions, 25 with an active Blureon SIP trunk), PBX Essential, PBX Business, PBX Pro (contact center), PBX Enterprise; each has everything in the one below; Business, Pro and Enterprise also come in an unlimited size. Paid monthly or yearly, or a lifetime licence (4 years of subscription). Prices: https://blureon.com/en/blureon-pbx/#pachete. Edge cases and limitations: resource requirements for the AI features are established when the deployment is sized, together with the Blureon team. ## Product: Blureon Phone A native SIP calling app for macOS (Swift/SwiftUI) and Windows (.NET/WPF), built on Sipral (https://sipral.org), a SIP engine written in Rust. Features: multiple SIP accounts (UDP/TCP/TLS, SRTP); full call control (hold, mute, blind/attended transfer, DTMF, recording, multiple simultaneous calls, voicemail/MWI, blacklist); BLF and presence with a floating bar; Asterisk/FreePBX feature codes (transfer, pickup, ChanSpy listen/whisper/barge, park, DND); PBX integration through AMI or an Agent WebSocket, with call enrichment (DID, route, IVR, queue, wait time); CRM integrations (Odoo, HubSpot, a custom API) that look up the caller by number and show their name; in progress: Salesforce, Microsoft Dynamics 365, Zoho CRM, Pipedrive, monday.com; SMS and WhatsApp from the app through the company's SMSWapi account (Pro and Enterprise); webhooks and commands run automatically on call events; history (CSV export), contacts (OS, local and remote); automatic provisioning from the licence key; auto-update. Security: TLS + SRTP; local storage encrypted with AES-256-GCM, with the key in the system's vault (Keychain on Mac, DPAPI on Windows); the app sends usage statistics, call quality and crash reports, tied to the computer for 24 months and then anonymised, never call content. Licensing: key format BP-XXXX-XXXX-XXXX-XXXX, tied to hardware, offline validation through a JWT; packages Phone Free (no cost), Phone Essential (free with a paid Blureon PBX), Phone Pro and Phone Enterprise (monthly or yearly subscription). Prices: https://blureon.com/en/blureon-phone/#pachete. Codecs: Opus, G.722, G.711 (PCMA/PCMU). Platforms: macOS Sonoma 14+ on Apple silicon (M1 or later; Intel Macs are not supported), Windows 10 build 1809+. ## What we don't do (deliberately) - We do not promise unconditional call continuity, nor activation timelines presented as a guarantee; we confirm them after reviewing the client's data and configuration. - We do not guarantee quality on the client's own internet segment (the last mile) — we recommend local QoS where it can be configured. - Blureon Phone never sends call content in telemetry. ## Technical FAQ Q: Is Blureon an operator or a reseller?
