Owned infrastructure
BRCK operates its own voice infrastructure so call quality, routing behavior, and troubleshooting are not outsourced to a black box.
SIP Trunking
Enterprise SIP Trunking Built for Reliability
BRCK delivers enterprise SIP trunking for organizations that need resilient voice connectivity, modern interoperability, and a team that understands what is actually at stake when calls stop flowing.
Why organizations move to BRCK
Replace inflexible legacy PRI or carrier trunks with IP-based voice connectivity.
Standardize around one provider across Teams, Webex, and PBX environments.
Reduce outage risk with redundancy, failover, and support from people who know the stack.
What it is
A simpler path from your phone system to the public phone network.
SIP trunking replaces traditional analog or PRI circuits with IP-based voice connectivity. Instead of managing expensive legacy lines, your PBX or UC platform connects securely to BRCK over the internet or private connectivity, giving you more flexibility, easier scaling, and cleaner administration.

Why BRCK
Telecom depth, modern execution.
A SIP trunk is only as good as the infrastructure and operational discipline behind it. BRCK combines both, which is why customers trust us for voice environments that cannot afford guesswork.
99.99% uptime target
Redundant architecture, carrier diversity, and proactive monitoring support the availability serious business voice deployments require.
Failover built in
Traffic can be routed intelligently around issues so a single carrier event or endpoint problem does not become an outage story.
Platform interoperability
Deploy BRCK with Microsoft Teams, Cisco Webex, 3CX, FreePBX, Asterisk, Zoom Phone, or virtually any SIP-compatible PBX.
Operational features included
Caller ID and CNAM support, call recording compatibility, E911 coverage, and number porting all fit into the same service model.
Real implementation help
BRCK supports migrations, cutovers, and deployment planning with engineers who understand how these projects fail and how to avoid it.
Architecture
How calls flow through BRCK
Whether you are running a cloud UC platform or an on-prem PBX, the call path stays clean: your users place or receive calls through your phone system, BRCK manages the SIP connectivity and routing logic, and the PSTN is reached through resilient carrier infrastructure.
Typical call flow
1
Users & devices
Employees use Teams, Webex, desk phones, softphones, or call center seats to place and receive calls.
2
Your UC or PBX
Calls route through Microsoft Teams, Cisco Webex, 3CX, FreePBX, Asterisk, Zoom Phone, or another SIP-compatible system.
3
BRCK SIP edge
BRCK authenticates the connection, applies routing logic, and maintains resilient trunking infrastructure.
4
PSTN delivery
Calls reach the public phone network with failover and carrier redundancy designed to protect uptime.
Included capabilities
More than basic connectivity
The service model around a trunk matters just as much as the trunk itself. BRCK helps customers cover the operational pieces that usually turn into separate projects.
Caller ID and CNAM support
Call recording compatibility
E911 included in service planning
Number porting with coordinated cutover support
