THE REFERENCE OF VOICE SWITCHING PLATFORM
FOR MASSIVE VOIP DEPLOYMENTS,
PSTN REPLACEMENT, AND MIGRATION TO IMS
CIRPACK
Carrier-grade Voice Switching
The NextGen Way
A UNIQUELY MODULAR PLATFORM
Using carrier-grade technology, Cirpack has developed a highly modular and scalable platform, incorporating all the com-ponents of a powerful public telephony switch in a compact, standards-based, and easy-to-manage. Leveraging the range of Cirpack media/signaling gateways, carriers can design central-ized or distributed architectures reaching small, medium, and large density POPs with the best price/ performance ratio.
FIELD-PROVEN TECHNOLOGIES
The Cirpack Softswitch platform handles several of the larg-est european VoIP deployments. It has demonstrated carri-er-grade reliability, offering primary line telephony services across very large and complex infrastructures. Service provid-ers around the globe are building on Cirpack’s extensive fea-tures set to deliver over broadband or maintain legacy tele-phony services via SIP, MGCP, or V5.2 access and handle highly demanding applications such as portability, interactive voice response or calling cards.
FROM TDM TO NGN TO IMS
The Cirpack Softswitch platform is a unique Class 4 (CTRS: Core Trunking & Routing Switch) or Class 5 (CTAS: Cloud Telephony Application Server) solution designed to replicate the features of legacy voice switches. It enables existing TDM telephony services and equipment to be maintained in Next Generation Networks (NGN) for service providers to expand their legacy PSTN while delivering VoIP services and start migration to IP Multimedia Subsystems (IMS) architectures.
The Cirpack Softswitch platform is the
next-generation telephony switch
op-erators need to launch their
next-gen-eration services: Voip, triple play,
Fixed-Mobile Convergence, etc.

Cirpack Softswitch Platform
POWERFUL TRUNKING
Working in conjunction with Cirpack Session Border Controller (SBC), it enables VoIP interconnection between operators and the connection of IP PBX with SIP. Thanks to media and sig-naling gateways installed across the voice infrastructure, the Cirpack Softwitch enables seamless interworking between the operator’s IP infrastructure and the PSTN. It supports all SS7 local variants and its advanced voice routing mechanisms en-able complex transit infrastructures to be deployed using both IP and TDM trunking.
OPEN & FLEXIBLE SOLUTIONS
Cirpack Softswitch Platform also comes with lawful intercept, emergency numbers, and local number portability features for full compliance with regulatory requirements. It can be en-hanced with third-party application servers connected via SIP, as well as legacy SCPs from intelligent networks via INaP CS1, to easily deliver value-added services from a single platform, leveraging the existing components of any carrier-grade infra-structure.
NETWORK FUNCTION VIRTUALIZATION
(NFV) SOLUTION
In addition to the hardware-software based platform, Cirpack Softswitch can also be delivered as a full virtualized solution based on Virtual Machine modules that can be run on any IT hardware selected by the operator network administrators. Cirpack virtualized Softswitch solution is compliant with ETSI NFV standard and compatible with the major virtualization hy-pervisors.
SMALL & VERY LARGE NETWORKS
The Cirpack Softswitch is the call controller, designed to offer primary line voice services over any broadband or legacy local loop. It is very scalable and can handle from 10,000 to 1,000,000 subscribers and from 32 to 8,000 E1, managing several million call attempts per hour (BHCA) from a single node, thus meeting operators’ demands for large and scalable network infrastruc-tures.
IP TDM TELEPHONY
Cirpack Softswitch is meant to deliver primary line telephony services over broadband infrastructures of any kind with SIP and MGCP. It can replaces legacy PSTN switches and deliver all POTS and ISDN services over v5.2 access networks to ease the migration of the largest PSTN infrastructures.
Cirpack Softswitch Platform is a
carrier-grade Cloud Call Control, delivering
ad-vanced Trunking (Class-4) and Access
(class-5) services across any broadband
or legacy local loop and core network.

FIXED-MOBILE CONVERGENCE
When connected to a mobile infrastructure (3G/4G or WiFi), the Cirpack platform enables fixed-mobile convergence servic-es that offer rservic-esidential and businservic-ess users unique experiencservic-es such as being able to choose their fixed or mobile phone to answer incoming calls, automatic routing of inbound calls to the proper terminal in the proper location, seamlessly placing and receiving calls over WiFi anywhere on the Internet, etc. Combined with the Cirpack Unified Communictaion applica-tion, the Cirpack FMC solution enables mobile PBx features even with legacy GSM phones.
With its Softswitch platform, Cirpack
offers operators the ideal solution to
quickly launch feature-rich broadband
services and easily migrate to an IMS
when needed.
