  • Alarm panels
  • Paging systems
  • Industrial phones
  • Legacy PBXs

Preserve existing infrastructure while modernizing

Replacing every analog device can create high capital cost, operational disruption and unnecessary project risk. The C7 Series allows organizations to keep critical analog assets while securely integrating them into SIP, VoIP and cloud communications environments.

Reduce capital expenditures

Instead of replacing every endpoint, organizations can migrate progressively. This lowers project cost, accelerates deployment, reduces downtime and extends the lifecycle of infrastructure that still works.

Replace legacy POTS services

Traditional copper and POTS services are being retired or becoming more expensive to maintain. The C7 Series enables POTS replacement, SIP trunk migration, hosted PBX connectivity, IP PBX modernization and analog continuity.

Improve business continuity

Analog devices often support emergency phones, fire alarm panels, security systems, production phones and utility-site communications. The C7 Series helps maintain these services during modernization.

Centralize voice infrastructure

Instead of managing disconnected analog islands, teams can gain centralized SIP routing, remote provisioning, monitoring, troubleshooting and operational visibility.

Carrier-grade reliability for critical environments

Mediatrix platforms are engineered for demanding enterprise, operator, government, healthcare, transportation, utility and industrial environments where reliability and lifecycle matter.

Where the Mediatrix C7 Series creates immediate value.

The C7 Series is valuable anywhere analog systems are trusted, deployed at scale and difficult to replace, but now need secure integration with SIP and IP networks.

C7 Series variants explained clearly.

Use the accordion to help visitors understand which C7 configuration fits their deployment before they contact M5 Technologies.

FXS variant — connect analog endpoints to SIP
FXS configurations are used when the site needs to keep analog endpoints such as phones, fax machines, intercoms, elevator phones, alarm panels or paging systems.
  • Best fit: analog endpoint modernization and POTS replacement.
  • Business value: keep existing equipment while moving to SIP/IP.
  • SEO intent: FXS gateway, analog telephone adapter, analog-to-SIP gateway.
FXO variant — connect PSTN trunks or legacy PBX lines
FXO configurations are used when the deployment needs switched-circuit network access, PSTN trunk connectivity, PBX trunk integration, survivability or fallback between legacy telephony and IP voice platforms.
  • Best fit: PSTN replacement, local trunk integration and failover calling.
  • Business value: bridge existing PSTN assets into a controlled SIP migration plan.
  • SEO intent: FXO gateway, PSTN gateway, legacy PBX gateway.
Mixed FXS / FXO deployment — one platform for complex migrations
Mixed deployments are useful when a site has analog endpoints and PSTN or PBX trunk requirements in the same migration project.
  • Best fit: SMBs, branches, multi-site enterprises and operators.
  • Business value: simplify migration architecture with one field-ready gateway family.
  • SEO intent: analog media gateway, branch voice gateway, legacy-to-IP migration.
Fax and modem over IP configuration
The C7 Series supports T.38 fax and clear-channel fax/modem pass-through scenarios for organizations that still depend on analog transport.
  • Best fit: healthcare, legal, logistics, public sector and industrial sites.
  • Business value: preserve critical fax and modem workflows during IP migration.
  • SEO intent: fax over IP gateway, T.38 gateway, analog modem over IP.
Branch survivability configuration
C7 deployments can support local continuity when WAN, cloud voice or centralized SIP infrastructure becomes unstable.
  • Best fit: distributed enterprises, operators, retail networks and remote sites.
  • Business value: maintain essential calling and routing continuity.
  • SEO intent: VoIP survivability, SIP failover, branch office voice continuity.
