SIP trunk/Business voice direct

Everything for perfect communication in the future

With voice-over IP solutions and direct connection to the Sunrise network

Progress cannot be stopped. To ensure that your company's telecommunications are always up to date, Business Sunrise offers future-proof solutions with the latest technologies. For example, Business voice direct, the direct connection of your phone system to the Sunrise network. Business voice direct can be used as a SIP trunk to connect an IP phone system. On request, the SIP trunk can also be configured as a high availability connection. Existing ISDN phone systems with BRI or PRI interfaces can also be used with a VoIP gateway. Good to know: You can always switch to SIP trunk at a later time without changing the port infrastructure – you simply choose when you would like to do this.
