Telecommunications — all from one source.
Landline, SIP/VoIP and mobile are part of IT — yet are often managed by three different providers. We bundle that: one contact, one contract, one billing partner.
Our areas
Landline
Classic phone lines, ISDN migrations, line procurement and number porting. We handle contracts, ordering and switching — including provider changes.
SIP & VoIP
Cloud PBX, SIP trunks and softphones. Site networking, mobile integration, home-office apps. GDPR-compliant German data centre hosting on request.
Mobile
Corporate SIMs, data plans, bundles with landline and roaming options. Independent advice on Telekom, Vodafone, O2 and resellers — and contract management.
What we do
- Provider comparison and needs assessment — independent, not tied to a single carrier
- Contract procurement and negotiation (landline, SIP, mobile)
- Number porting and line switching — coordinated without downtime
- PBX setup: cloud PBX, routing, voicemail, queues, recording
- Mobile device management: roll out, bill and replace corporate SIMs
- Integration with CRM and AI telephony (call logs automatically in the system)
- Invoice review and tariff optimisation — ongoing, not just at contract end
Related: AI telephony
A modern SIP/VoIP system is the foundation for AI telephony — the AI agent plugs into the inbound call flow and handles first contact, triage and appointment booking.
Who it's for
- SMBs with distributed sites or home-office share
- Companies that have not yet migrated ISDN and face carrier pressure
- Businesses that want landline, SIP and mobile bundled at one partner
- Practices, law firms, tradespeople — wherever "phone" is business-critical
