PSTN to All-IP

The migration to IP-based telephony is inevitable. With a major reduction in infrastructure and operational costs, IP telephony has grown exponentially and gained popularity in the past two decades.


Although inescapable, the transformation represents an extraordinary business opportunity for telephony and service providers willing to ultimately unplug their public-switched-telephone network and replace it with an all–Internet Protocol (IP) network for delivering voice services.

PSTN to All-IP – What We Offer

M5 Technologies offers a complete and cost-effective VoIP CPE portfolio (“Mediatrix”) that enables mobile and fixed providers to deliver SIP trunks to their customers, without any of the inconveniences of migrating a telecommunication system.

Through the deployment of on-premises SBCs – Session Border Controllers, alongside with VoIP gateways and analog adaptors, M5 Technologies (also known by its reliable and well-known product brand Mediatrix) allows for a seamless transition from analog and TDM systems to IP services.

Migrating from PSTN to IP with Mediatrix

Reliable and cost-effective, our Sentinel SBC overcomes every challenge of the transition from an analog or digital PSTN network to the IP by reducing infrastructure and operational costs. Superior voice quality is guaranteed and next-generation communication services are supported.

Main Benefits

1. Most interoperable brand on the market

  • With an endless list of codecs and protocols available in the market, Mediatrix is proven to be widely interoperable with the great majority of legacy and IP equipment including TDM and IP-PBXes; analog, digital, and IP phones; faxes, modems, and PoS).
  • Mediatrix is present in more than 100 countries and formally certified with the most relevant equipment manufacturers, softswitches, and Cloud Communications platforms across the globe, including Cisco, Mitel, Unify, Panasonic, Alcatel-Lucent Enterprise, Metaswitch, Ericsson, and others.

2. All-in-one pay-as-you-go SBC designed for scalability

  • Sentinel SBC is the ultimate solution for a great variety of scenarios (including SIP trunking, network demarcation, survivability, third-party application integration, and more). In addition, this modular multi-business platform performs SIP normalisation translating any vendor implementation into a single well-defined SIP interface, making sure all legacy and IP equipment (regardless of the brand) will connect smoothly and work properly.
  • The modular design of Sentinel SBC provides the ability to accommodate for communication systems of any sizes using any technology. Sentinel supports analog FXS and FXO, digital ISDN E1/T1 and BRI, and IP systems, making upscaling much simpler and cheaper. Customers can order individual modules (such as telephony cards and SBC licences) or a combination of them assembled at the factory into a Sentinel base unit, or added to previously deployed units.

3. Enable next-generation communication services

  • Non-Voice communications can be a big challenge for many providers but we are experts at that! Throughout the years, playing an essential role in the successful SIP migration of many carriers/providers, we developed an in-depth understanding and ability to excel at all non-voice communication applications, i.e. legacy faxes and modems as well as efficient support to Hosted Telephony and UCaaS applications.
  • Furthermore, we understand that a full SIP migration (especially when it is done at once) may be unrealistic for some companies. Due to the high costs of upgrading the entire infrastructure into an all-IP system, businesses can opt for a gradual Legacy-to-IP transformation or keep a hybrid system. Regardless of the scenario, our portfolio of VoIP solutions guarantees no disruption of customer service and, as consequence, minimal churn. Sentinel also allows for integrating future services in the operator’s portfolio that can generate additional revenue.

 4. Manageability and long-term support

  • Mediatrix SBCs and gateways support Zero-Touch Provisioning and offer extensive management capabilities. Its own Cloud-based Element Management System, Virtuo EMS, ensures easy remote installation, configuration, license activation, monitoring, and troubleshooting for Mediatrix unit operations. This reduces OPEX and the need for on-site technical support.
  • M5 Technologies is a VoIP expert operating since the early ’90s. Over the last 25 years, millions of devices worldwide have been using our patented SIP technology. We have a deep knowledge of E1/T1/R2/BRI and FXS/FXO analog appliances, whose technologies are being phased out of the product lines of many competitors, but not us. This gives us the ability to continue supporting legacy technologies, besides adapting our products and portfolio to quickly meet customer’s needs.

Zero-Touch Provisioning Solution

Service providers, in order to perform rapid and flexible deployments and properly serve the end-costumer, need a strategy to maximize device management. In this connected era, it can become difficult to keep track of every single device while keeping the costs at a minimum. At M5 Technologies , we believe that innovation is the best way to approach this problem.

M5 Technologies-telephony-voipOur solution: Zero-Touch Provisioning

The Virtuo Platform and its Zero-Touch Provisioning (ZTP) feature is an essential part of a service provider’s strategy to reduce operational costs, develop revenues, and increase customer satisfaction while deploying Mediatrix products.

As service providers’ costumer base grow, the number of deployed devices grows as well. As soon as this happens, good provisioning, management, and monitoring tools become essential to:

  • Standardise and automate the deployment process.
  • Minimize truck rolls and remove pressure on the configuration/installation team by remotely configuring and accessing devices.
  • Give insights on the current system health status to the operation department to detect and diagnose issues before the end-user can see them.

Keeping in mind service providers goals to create incremental revenues and increase operational efficiency, Virtuo gives them a cutting-edge management tool with a low total cost of ownership. M5 Technologies’s Virtuo EMS adds value to service providers with benefits such as:

  • Simplified inventory management: avoid having multiple software configurations in stock.
  • Zero-touch provisioning: automatically configure and update devices when the device is first turned on.
  • Redirect server feature: dynamically connects to an existing management system.
  • Cost reduction: eliminate the need for a technician to manually apply changes to a device.

Protect the Edge of Your Network

The public network offers Service Providers the possibility to expand their offering without any frontiers. This is also an opportunity for intruders to exploit security weaknesses at the edge of the network and make fraudulent use of the services.

Unprotected networks are also subject to several attacks like denial of service and breach of confidentiality.

Mediatrix provides advanced SIP and IP Security mechanisms to protect the edge of the network, providing powerful security features to monitor and control any attempt to access the network.

Offer Survivability and Quality of Service

Service quality and continuity are paramount to a successful service provider business. In case of WAN failure, Mediatrix will ensure the internal call control while redirecting external calls to a secondary, geo-redundant server or to the PSTN, if available. Failover and fallback are completely seamless and transparent to the phones and PBXs in the enterprise.

Traffic shaping and call admission control ensure that the user experience is safeguarded.

Connect any device to your network

While the core infrastructure is 100% prepared to deliver communication services, the equipment sitting at customers’ premises may not be that ready to enable SIP Trunking or Hosted Services right away.

When the transition to a full IP solution is not an option, Mediatrix multi-service platforms allows for the conversion of any legacy and SIP-based communication systems into a single and normalized SIP interface.
