Systems and clients
Agree the platform, calling and devices together.
A phone system, its external calling service and the devices or apps used to answer calls are different parts of the setup. Confirm each part before choosing or changing your arrangement.
Teams Phone, Asterisk/FreePBX and 3CX
CompTech supplies and manages these phone-system options, including hosted and cloud-managed phone systems. Discuss the current platform, who needs to make or receive calls and what must remain connected before agreeing the solution.
Desk phones
Snom is CompTech’s recommended phone brand. Choose suitable devices for the agreed system and confirm model compatibility and any required licences before purchase.
Softphone support
Support and management for softphone clients, so your team can use an agreed app-based calling setup. Confirm client, account and device requirements with the selected platform.
Phone-system management does not automatically include external calling, licences, handsets or every client feature. Agree the provider responsibilities and separate charges in the proposal. Microsoft Teams meetings alone do not establish a complete external phone service.
