What ccn does

ccn (legal entity: ccn Services GmbH, with sister entity ccn corporate communication networks GmbH) is a Munich-headquartered, privately held German telecommunications carrier founded in 2002. The company provides a white-label backend infrastructure for cloud-based voice and connectivity services, operating entirely from German data centers under BNetzA registrations 09/186 and 04/169, with full DSGVO and TKG compliance. Its go-to-market is exclusively B2B2B, serving IT-Systemhäuser, IT-Dienstleister, and IT-Distributors who resell ccn services to end business customers under their own brand via a back-to-back partnership model.

The product portfolio is unified around five interconnected offerings: bluePBX (a fully managed Yeastar P-Series Cloud PBX branded 'Yeastar Trusted German Cloud by ccn'), blueSIP (high-availability SIP trunks with bundled and pay-per-use tiers), blueSIP Teams Connect (a Microsoft Teams-certified Direct Routing Alternative without local SBC), blueFAX Online (cloud fax with REST API and Yeastar Linkus integration), and Business Internet (VDSL/Fiber up to 250 Mbit/s). Underlying technology is built on VoIP/SIP standards, T.38 fax-over-IP, and integration with SIP-capable PBX platforms (Yeastar, 3CX, STARFACE) and endpoint vendors (Yealink, Snom, Poly, Grandstream, Gigaset). Operational support includes 24/7 monitoring, 2nd/3rd-level support, and guaranteed SLAs.

Revenue is generated primarily through subscription-based recurring monthly billing (€35–€336/month for blueSIP, €59–€99/month for Business Internet, usage-based for blueFAX), supplemented by professional services for consulting, migration, and architecture. The model converts IT partners' on-premise telecom expertise into a recurring SaaS-style revenue stream without capital expenditure on their side, while ccn retains infrastructure ownership and operational risk. Fritz Welter serves as Managing Director of both legal entities. The company operates exclusively in Germany with no disclosed geographic expansion.

Core offering

ccn provides cloud-based telecommunications backend infrastructure for IT-Systemhäuser, IT-Dienstleister and Distributoren in Germany, including a fully managed Yeastar P-Series Cloud-PBX (bluePBX), high-availability SIP-Trunks (blueSIP), Microsoft Teams telephony integration (blueSIP Teams Connect), cloud-based online fax (blueFAX) and Business Internet access (VDSL/Fiber). Partners resell these subscription services to B2B end customers under their own brand in a white-label back-to-back model, with ccn operating the platform, data centers, monitoring and 2nd/3rd-level support.

Product overview

ccn operates as a backend infrastructure provider and managed service platform for telecommunications, offering a unified portfolio of five interconnected cloud-based products: blueSIP (SIP-Trunking), bluePBX/Yeastar Trusted German Cloud (Cloud-PBX), blueSIP Teams Connect (Microsoft Teams integration), blueFAX Online (cloud fax), and Business Internet (VDSL/Fiber connectivity). The architecture is designed specifically for IT resellers (IT-Systemhäuser), IT service providers, and distributors, who sell and maintain customer relationships while ccn operates the underlying platform, infrastructure, and technical support. The product portfolio emphasizes recurring revenue through subscription-based monthly billing, with a back-to-back partnership model where ccn remains invisible in the background while partners retain customer ownership. All services run in German data centers, are DSGVO/TKG compliant, and support bundling for complete telecommunications solutions.

Broad incumbents

• Deutsche Telekom (T Business): Incumbent German carrier offering Cloud-PBX, SIP, Teams integration, and internet under its MagentaBusiness portfolio. Competes for the same end customers as ccn but with much broader brand, scale, and bundled connectivity.
• Vodafone Germany (GigaBusiness): Major German B2B connectivity and UC provider offering cloud telephony and Teams integration as part of a broader enterprise portfolio. Comparable in product scope but operates at much larger scale and broader geographic reach.
• 1&1 Versatel: Large German B2B carrier with SIP trunk, cloud telephony, and fiber internet products. Comparable connectivity and voice portfolio, but competes primarily as a direct carrier rather than white-label backend.

Direct peers

• sipgate: German VoIP and SIP trunking pioneer offering business telephony to SMBs and resellers. Closely comparable to ccn's blueSIP trunk and small-business telephony focus in the German market.
• 3CX: International software PBX vendor with strong presence in Germany via partners; ccn's blueSIP is explicitly compatible with 3CX. Comparable as a Cloud-PBX target for the same IT-Systemhaus resellers.
• nfon AG: Munich-headquartered cloud PBX and UCaaS provider serving SMBs and channel partners across Europe. Most direct competitor to ccn's German-data-center white-label Cloud-PBX model, with overlapping IT-Systemhaus/MSP channel and SIP-trunk portfolio.
• HFO Telecom: German wholesale SIP trunk and cloud telephony provider resold through IT-Systemhäuser. Comparable to ccn's blueSIP in product, channel, and German regulatory positioning.
• Placetel (Enreach): German cloud telephony provider offering Cloud-PBX, SIP trunking, and Teams integration to SMBs and partners. Competes head-on with ccn in the German IT-Systemhaus channel and has very similar product positioning around Microsoft Teams Operator Connect.
• STARFACE GmbH: German PBX manufacturer whose cloud platform is interoperable with ccn's blueSIP trunk and serves the same IT-Systemhaus channel. Comparable because it sells both direct and via German system-house partners.

Emerging players

• easybell: German VoIP/SIP trunk and cloud PBX provider focused on SMBs and resellers. Comparable product scope to ccn but smaller scale and a more direct (less white-label) go-to-market.
