Managed SIP Trunking
Facilitates the transition to IP communication and
ensures the highest level of security

The state-of-the-art standard for landline calling

Sunrise enables companies to have an IP connection to the public telephone network via SIP trunk. Session Initiation Protocol (SIP) is the state-of-the-art standard for landline calling. Session Border Controllers (SBC) are used to ensure interoperability between IP-based communication systems.

The session border controller cluster redundantly hosted in two Sunrise data centers, establishes the connection between the Work Smart Application (UCC) and the public telephone network, which ensures that the communication infrastructure is comprehensively protected and flexible.

We offer this SIP trunk connection, which ensures a high level of reliability, as a Managed Cloud Service.
