Volume plans for businesses with high call volumes
With our volume plans you can plan your telephony costs reliably. You book a minute package in addition to your SIP trunk channel package. Depending on your call volume, a minute bundle can cost less than pay-as-you-go billing. The minutes apply to all registered devices. Depending on your call volume, this can cost less than a flat rate per extension. Once your included minutes are used up, you continue calling at our low standard rates.

Frequently asked questions
What is a SIP trunk?
A SIP trunk connects your phone system to the public telephone network via the internet. It replaces the traditional phone line – with as many simultaneous calls and extensions as you need.
Can I keep my existing numbers?
Yes. We transfer your single numbers and number blocks from your current provider and take care of the porting.
Can I continue to use my existing phone system?
Usually yes – provided your system supports SIP trunks. Get in touch and we will be happy to check this for you. Alternatively, our HK:net Cloud PBX is the ideal partner.
How many voice channels do I need?
One voice channel corresponds to one simultaneous call. So what matters is how many calls take place at your company at the same time – not how many employees you have. The number of channels can be adjusted at any time.
What internet bandwidth do I need?
As a rule of thumb, allow around 100 kbit/s per simultaneous call for upload and download, plus a little headroom. With a fibre connection from us, you are on the safe side.
