Executive Interview

Metaswitch supplies the interconnect side of the IMS core – essentially routing and security for voice calls out of NIMS into the many interconnected networks within the wider Deutsche Telekom Group. In more technical terms, that means a large deployment of SBCs across all the NIMS sites, plus a lot of collaborative work on the automation and configuration management processes for its own components and wider processes for NIMS.

A collaborative approach to NIMS resulted in an open two-way learning process around the key pain points and technical possibilities of automation in cloud – which all parties to the project have benefitted from.
