Software vendor Metaswitch announced today that it has acquired OpenCloud to enhance VoLTE services, which Metaswitch offers to both mobile and converged network operators. Terms were not disclosed.

Metaswitch plans to integrate OpenCloud’s Rhino Telecom Application Server (TAS) with Metaswitch's Clearwater IMS Core and Perimeta virtualized session border controller.

Rhino TAS is an open platform that is made to be built out by network operators using application performance interfaces (APIs) and SDKs. Metaswitch’s Clearwater core provides IP multimedia subsystem (IMS) functions that can be deployed in cloud infrastructure when delivering communication networks. Things like VoLTE and the Internet of Things (IoT) have fueled the need for these functions, the company claims.

OpenCloud was founded in 2000 and is headquartered in Cambridge, United Kingdom.
