Metaswitch and Hewlett Packard Enterprise (HPE) today partnered to bring virtualized IP Multimedia Subsystem (vIMS) to telcos. They’ll use Metaswitch’s vIMS integrated with HPE’s Helion OpenStack Carrier Grade and NFV Director orchestration platform.

They say their combined vIMS offering accelerates fixed and mobile network deployments of advanced voice services, including VoLTE, on private, public, or hybrid cloud infrastructures.

With this integration, Metaswitch also becomes the first vendor to complete all levels of certification in the HPE OpenNFV Partner Program.

The partners say the cloud-native IMS installs in hours instead of the usual months. It’s now ready for production IMS deployments.

Metaswitch is one of the companies using the open source Cloudify code to orchestrate VNFs, including its vIMS and its virtual session border controller (vSBC).

For its part, HPE continues to sign up new partners in its OpenNFV program. Samsung recently joined as a network equipment provider. Samsung will provide carrier-grade virtual network functions (VNFs) for mobile networks, such as its virtualized evolved packet core (vEPC).
