We provide every component you need, whether you want to extend your existing phone system with an IP-based solution, replace it entirely, connect home office users, or integrate additional locations. Based on your specific requirements and preferences, we will advise you on the business solution that fits your organisation best.

Your VoIP Business Connection

The ideal connection for your business in a modern next-generation network

For your business connection, we provide exactly as many phone numbers as your company needs.

Thanks to state-of-the-art Voice over IP technology, you benefit from crystal-clear HD voice quality.

Individual Numbers or Number Blocks

Single numbers or full number blocks, we provide the exact quantity you need for each of your locations, across all German area codes, without long waiting times.

Trunks vs. Accounts

Does your existing phone system require a SIP trunk? Or does it operate with a login and password via SIP account? We provide the right technology for your connection.

Number Porting

If your phone numbers are currently hosted by another provider or network operator, we can port them to our network for you.

Line Capacity

Depending on your call volume, you can add channels quickly and flexibly whenever needed. For high-volume environments, up to 1,000 simultaneous calls are possible.

SIP Telephony

A flexible, high-quality VoIP phone connection for your business

We design the right IP connection around your specific needs. Whether you want to add extra VoIP lines, migrate an existing connection, or integrate additional sites, we have the right solution.

SIP Trunk Solution

Phone Numbers

Flexible provisioning of individual numbers or complete number blocks.

We can provide individual phone numbers, multiple numbers, or entire number blocks. If you would like to keep your existing number, we can port it to our network free of charge.

Whatever your requirements, we will provide the solution that fits!
