What VoIP & Telecoms covers
- Cloud voice platform with number porting from your current provider.
- Apps for desktop and mobile, or integration with Microsoft Teams.
- Call flows, auto-attendants and out-of-hours routing.
- Quality of service configuration on your network so voice takes priority.
Not every provider does all of it. Ask what is inside the monthly fee and what is billed as a project.
What to ask before you sign
- Which platform is behind the service, and are we on your tenant or our own?
- What is the contract term and the price after any introductory period?
- How is call quality monitored, and who fixes it when it degrades?
- Can we keep our numbers if we move provider?
