SME migrating a phone system
You have a traditional phone system (PBX, PABX, Centrex) and want to consolidate your telephony into Teams. You want to avoid managing two separate tools for collaboration and calls.
✓ Migration with no downtime✓ Training included
This service is right for you if...
Multi-site mid-market company
You have several sites with heterogeneous telephony setups. You want to unify telephony on a single Microsoft platform, accessible from any workstation or mobile device.
Full Teams organisation
You already use Teams for collaboration but your external calls still go through a traditional operator. You want Teams to be the single entry point for all your inbound and outbound calls.
What is included in the Teams Phone professional service
Audit of the current installation
Analysis of your existing telephony infrastructure (PBX, SIP lines, numbers, call flows, volumes). We identify technical constraints and size the right solution before touching anything.
Number portability
We manage the transfer of your existing numbers to the Dstny operator. Your clients call the same numbers as before. No downtime, no number loss, no visible change for your contacts.
Direct Routing or Operator Connect configuration
We configure the solution best suited to your environment — Direct Routing for custom architectures, Operator Connect for native and simplified integration. Dstny is the Microsoft-certified partner operator providing PSTN connectivity.
Softphone and IP phone deployment
Installation and configuration of Teams applications on workstations, mobile devices and physical IP phones if required. Every user can make calls from their computer, smartphone or desk phone.
User and administrator training
Practical training for end users (making a call, transferring, voicemail, meeting with inbound call) and Teams administrators (number management, call policies, queue supervision).
Post-migration support
Dedicated support after go-live. We remain available to adjust configurations, resolve incidents and answer user questions during the adoption period.
