C9 COMPLETE COMMUNICATIONS ASSESSMENT
Ask C9 to assess the whole communication layer before you buy anything.

YEALINK HARDWARE · MICROSOFT TEAMS
Keep the physical phones and the collaboration platform working as one system.
C9 can provide Yealink desk phones and Teams-ready hardware where staff need tactile calling, shared-area devices, reception visibility or meeting-room audio.
For Microsoft 365 teams, C9 also manages the Teams Calling pathway, so users, numbers, policies, devices, call queues and support do not become separate projects.

Useful C9 tipCheck Voice Readiness
Internet requirements and hardware compatibility
VoIP Phone runs over the network your business already depends on, so call quality is shaped by more than the phone plan. Internet stability, bandwidth, router setup, Wi-Fi, failover and supported hardware all matter.
Before C9 GROUP recommends a managed VoIP path, we check the practical requirements that can affect voice quality on day one and after go-live.
VoIP call quality depends on stable upload and download bandwidth, low latency, low jitter and minimal packet loss. C9 checks whether your internet, router, LAN and Wi-Fi can keep calls clear before numbers are moved.

Questions about managed VoIP Phone
VoIP is the calling technology that carries voice over an internet connection. Hosted PBX is the cloud phone system that manages users, extensions, queues, voicemail and routing. C9 helps you plan both together.
