HK:net Cloud PBX
Run in Düsseldorf. Connected everywhere.

With HK:net Cloud PBX, your team makes calls in the office, from home and on the move – on the computer, in the browser, via the smartphone app or with a suitable IP phone. Live chat and – depending on the edition – video conferencing complement the telephony.
We run your system on a high-availability cluster in our data centre in Düsseldorf and take care of operation, maintenance, updates and backups.
The connection to the public telephone network is made via SIP trunks. We can port your existing numbers on request.
Telephony, contact centre, video conferencing, messaging and integrations – in one cloud phone system, with more than 100 features out of the box.
Telephony
Call control, forwarding, voice menus (IVR), time-based routing, recording and voicemail are all included out of the box. With the HK:net Cloud PBX apps, your employees make calls on their computer, in the browser or on their smartphone when on the move – with the same direct dial number. The operator panel shows all calls at a glance.

Contact centre
Queues, ring groups and voice menus route callers to the right person. Supervisors see waiting times and workload live on the wallboard, callers can request a callback instead of waiting – and reports show where adjustments are needed.

Video conferencing
Video conferences run directly in the browser – no download needed, encrypted. With screen sharing, in-meeting chat, moderation features, waiting room and password protection. You send invitations as a link or collectively by email. Included in the Ultimate edition.

Omnichannel messaging
Website chat, WhatsApp, SMS and Facebook all arrive in one shared inbox. Chats can be assigned or passed on to colleagues, turned into a call with one click, and are automatically matched to the right contact in your CRM.

Integrations
Make calls directly from Microsoft Teams and Outlook, start calls from your CRM or helpdesk and have them logged there automatically – for example with Salesforce, HubSpot, Zoho, Microsoft Dynamics 365 or Zendesk. Open interfaces (APIs) are available for your own integrations.

With the graphical designer, you decide what happens to calls and messages – by drag and drop, with no programming at all. Conditions, announcements, forwarding and queries in your CRM or database can be combined freely. Available in the Ultimate edition.
