One communication setup for your Swiss locations
Reduce the number of systems and providers your IT team has to coordinate
Business telephony becomes more difficult when phone systems, numbers, connectivity, and support are managed separately. Virtual-Call helps companies coordinate cloud PBX, SIP Trunking, business numbers, and, where appropriate, Business Internet within one communication environment.

- Connect headquarters and branch locations
- Reduce separate support paths
- Add integrations according to your IT environment

Keep business numbers available across different workplaces
Employees do not need to depend on a single office desk to use business telephony. Depending on the configured setup, users can work with desktop and mobile clients while their business number and call routing remain centrally managed.
- Office and remote workplaces
- Desktop and mobile clients
- Central number management
