Cirpack supplies software for telecom operators and service providers: an IMS core network with a Multimedia Telephony Application Server, a Session Border Controller (SBC) for SIP interconnection and network protection, number-portability platforms and a managed core-network service. The products are software-based, virtualisable and modular, built on 3GPP standards such as TS 24.229. Operators install them in their own infrastructure; in addition, Cirpack offers Uniquity, a cloud PBX service that it operates itself.
Cirpack is a French company based in Issy-les-Moulineaux and describes itself as an independent, privately owned European vendor; no foreign parent company is mentioned. When installed in-house, the operator decides where traffic and subscriber data resides. For the Uniquity service run by Cirpack, the website does not state a data location, so ask. For a European operator this means a supplier under European law with the option of fully self-controlled hosting.
