Trading interruptions
Voice disruption can delay decisions, break workflows and increase exposure.
Banking & Capital Markets Communications
Protect every trade and every critical financial conversation.
M5 Technologies helps banks, trading floors, exchanges and financial institutions secure SIP infrastructure, connect Microsoft Teams and PBXs, preserve branch and analog services, and design resilient voice continuity.
Trading-floor continuityProtect time-sensitive voice workflows and failover paths.
SIP edge securityControl trunks, peers, routes and topology exposure.

The customer problem
In finance, a voice outage becomes operational, financial and reputational risk.
Trading desks, treasury teams, branches, contact centers and executives depend on multiple carriers, PBXs, Teams, SIP trunks and legacy services that must operate as one controlled communications environment.
02
SIP attacks and fraud
Unprotected trunks can expose the institution to scanning, abuse and service disruption.
03
Platform fragmentation
Teams, PBX, contact center and carrier systems may not interoperate consistently.
04
Continuity gaps
Carrier, site, cloud or equipment failures can remove critical calling paths.
Customer impact: without a controlled voice architecture, the institution can face inconsistent routing, difficult incident response, fraud exposure and unreliable disaster recovery.
How M5 resolves the use case
Create one secure control layer between users, platforms and carriers.
M5 separates SIP security, interoperability and legacy modernization so the institution can manage risk without replacing every system at once.
Secure the SIP boundary
Sentinel SBCs control signaling, routes, peers and topology between trusted and external voice domains.
- Topology hiding and normalization
- Peer and routing policy
- TLS/SRTP where supported
Unify communications platforms
Connect Teams Direct Routing, PBXs, contact centers and carrier trunks through a managed interworking layer.
- Teams and PBX coexistence
- Carrier interoperability
- Centralized routing control
Preserve continuity
Mediatrix gateways and resilient SBC designs maintain branch, analog and emergency services during modernization.
- Legacy and analog interworking
- Failover and DR planning
- Phased migration by site

FAQ
Questions banking, trading and IT teams commonly ask.
Why do financial institutions need an SBC?
An SBC controls SIP interconnection, routing, topology, normalization and security between trusted financial systems and external carriers or cloud platforms.
Can M5 support Microsoft Teams Direct Routing?
Yes. Sentinel SBCs support Microsoft Teams Direct Routing and can help connect Teams with carriers, PBXs and other enterprise voice systems.
Can branch analog devices remain in service?
Yes. Mediatrix gateways can preserve selected fax, alarm, elevator, ATM-adjacent and emergency-phone services during migration.
How should trading-floor continuity be designed?
It should include redundant trunks, SBCs, routes, power, data centers and documented failover procedures validated against real call flows.
Can the solution be virtualized?
Yes. Sentinel CS supports virtual SBC deployment for centralized, cloud or hybrid financial voice architectures.
What is the first step?
Start with an assessment of sites, trunks, voice platforms, critical users, emergency calling, analog dependencies and disaster-recovery requirements.
Financial communications review
Map the communications risk before the next outage or migration.
Provide a high-level overview of the current environment. M5 can help identify the SBC, gateway, interoperability and continuity questions that should be resolved.
