Microsoft Teams calling: the phone system you already have open
If your company lives in Microsoft 365, telephony can move into Teams: one client for chat, meetings and calls. KHTC compares the connection paths – Operator Connect, Direct Routing or Microsoft Calling Plans – ports your numbers, designs queues and auto-attendants and manages the carriers behind it. Provider-neutral and free of charge for you.
Typical problems we encounter
- a separate phone system beside Teams doubles everything
- Operator Connect vs. Direct Routing – sales decks instead of clarity
- call queues and reception flows nobody has mapped to Teams
- licence costs unclear until the first invoice
- carriers point at Microsoft, Microsoft points at carriers
What KHTC delivers
- Fit check: does Teams calling actually fit your call flows – or does a cloud PBX serve you better? Honest answer first.
- Connection path: Operator Connect, Direct Routing or Calling Plans – priced and rated for your size and setup.
- Numbers & porting: existing ranges ported into Teams without a silent minute.
- Call-flow build: auto attendants, queues, opening hours and voicemail – configured with the teams that use them.
- Operations: one contact for carrier and configuration questions – afterwards, too.

- hybrid and remote teams
- companies replacing a PBX anyway
- IT teams wanting one platform less
Operator Connect or Direct Routing?
Operator Connect is the managed path: the carrier appears natively in the Teams admin centre, setup is fast, operations are shared. Direct Routing buys maximum flexibility (special cases, analogue devices, exotic routing) at the price of more moving parts. For most mid-market setups Operator Connect wins on total cost – we calculate it for yours instead of assuming.
From the field
The hidden cost driver in Teams telephony is rarely the carrier – it is unplanned licensing: the right mix of Teams Phone licences decides the monthly bill.
FAQ: Teams calling
Short answers – happy to go deeper in a personal conversation.
Do we need new numbers for Teams calling?
No – existing German number ranges are ported into the chosen carrier and appear in Teams as before.
What happens if Teams is down?
We design fallbacks: parallel mobile routing, emergency forwarding and, for critical roles, a survivability concept – so an outage is an inconvenience, not silence.
Which licences do we need?
Typically Teams Phone on top of your Microsoft 365 plan, plus the calling path – we map the exact mix to your users so nobody pays for unused capability.
Can reception and queues really work in Teams?
Yes – auto attendants and call queues cover the classic reception logic; we build and test them with the people who run your front desk.
