Business communications

Phone systems that fit how your team works.

CompTech supplies and manages Teams Phone, Asterisk/FreePBX and 3CX phone systems, including hosted and cloud-managed options, with Snom as its recommended phone brand and support for softphone clients.

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.

For product requirements, see Microsoft’s Teams Phone overview, the Asterisk project, FreePBX and 3CX phone-system information. Product names checked 7 October 2026; these links do not imply a CompTech partner accreditation.

Scope the change

Start with your present calling arrangement.

Tell us your current system and calling provider, user and device numbers, existing numbers to consider and how office or remote staff need to answer calls. Include contract dates, current licences and any dependencies on other suppliers.

We will agree the work, equipment, calling and licence requirements, support responsibilities and price before delivery. Number changes or transfers need their own agreed scope and provider coordination.
