Cordboard Virtual Switching System:
Deploy a fully-compliant US CLEC switch in 3 minutes
The telco features you expect, with the DevOps tooling you need
21st century switching
The Telstar VSS has all of the features that you've come to expect from your current carrier switch (DMS100, Metaswitch, Ribbon, Netsapiens) but is configured through a unique infrastructure as code engine. The entire switch config, from translations to lines to recordings is managed through a single human and machine readable YAML file, enabling the same automation and DevOps tooling that has become standard in IP network operations. Every configuration change is assigned a unique revision id and stored separately. Once you've logged a configuration change into the system, applying or rolling it is as simple as making a web request. Since all config data is stored in a text-based format, configs can simply be diffed to find the location of a problematic change, enabling instant remission. A Friday night config change will never cause a mad scramble to the CO again.
End routing mysteries
See why every call routed the way it did. The 1VSS records every routing rule and translation used to route a call, allowing easy and simple debugging. In the event of a call not routing properly, or a certain dialing pattern exhibiting aberrant behavior, examining the route log will show the call's exact path through the switch, and highlight all rules and trunk groups that were matched. Problems can be diagnosed and fixed without time consuming and difficult manual test-and-trace work. Call CDRs also log PDD, media quality, signalling IPs and everything else you need to debug a call, on a per-leg basis.
Reliability from the ground up
Our system is built from the ground up with reliability as an iron law. All hosted services are deployed on an anycast network, with multiple running regions. Our system has no master region, with all regions capable of offering all services independently. We provide a single set of SIP signaling IP addresses that is spanned across the entire country, automatically routing your own and your customer's traffic to the lowest latency zone, keeping voice quality high. In the event of a site failure for any reason, traffic is seamlessly rerouted to the nearest operating site, making any outage invisible.
Core carrier features
Our system is built from the ground up for regulated carriers and ISPs, containing the routing and compliance features that you've come to expect. Translations can match LATA, OCN, Rate Center, LRN, or dialed number and matches can be made using asterisk-style patterns or full regex. Each line or trunk can be assigned to an independent translation chain. Local Number Portability data is sourced directly from NPAC nightly. The 1VSS supports STIR/SHAKEN signing and certificate management. A full inheritance tree for all translation and resource types is supported, allowing for easy deployment of sub-carriers or hosted PBX products.
Solutions for every segment
Class 4 and ITSP
The Cordboard VSS system tackles your toughest routing challenges and highest call volumes. With integrated support for LRN dips, jurisdiction-based routing, multi-deck effective cost LCR, and per tenant routing the VSS system can support any tandem use case. The VSS also includes integrated monitoring of trunk PDD, RTP quality, ASR, and ACD with free range queries, enabling easy detection of broken or poorly preforming trunks. In the event of a customer reporting broken routing, debug the issue in seconds with a forensic routing record query.
ISPs, Class 5, and ILEC
Looking to deploy double or triple play packages for your subscribers? Struggling with a legacy DMS100 or 5ESS? Concerned about the metaswitch acquisition? The 1VSS allows you to maintain the features and uptime that you've come to expect in a traditional switch, while allowing you to take advantage of modern tooling and features. Gain modern IaC management tools and increased visibility into call flow with a complete record of all decisions made while routing a call, and instantly revert bad config changes. All while maintaining support for the subscriber features, specialty regulated services and interworking standards that frustrate most efforts at switch migration.
MSP and PBX
As a managed service provider, providing phone services to your customers gives you a reliable additional revenue stream while increasing customer retention. At the same time, voice services can be notoriously difficult to provide and manage reliably. The 1VSS is a natively multi-tenant system which enables you to provide these services based on a rigorously tested set of configuration templates. Leverage multi-level reseller chains and per-tenant CDRs to provide whatever services fit best within your business model, while developing on a platform which will grow as your business does.
Arriving in v1
The following essential compliance and regulatory features are locked into the general-availability feature set and in final development now.
PBX call features
Blind and attended transfer, hold, park and pickup, three-way calls, and music-on-hold.
Analytic CDR store & alerts
Free-form queries across trunks, lines, jurisdictions and tenants, with ASR/ACD aggregates and real-time alerting for outages and fraud.
Equal-access signalling
CIC/LRN/ANI2 SIP header signalling for carrier interconnect and line/trunk flags to steer routing at the subscriber level.
CALEA lawful intercept
Integrated ATIS-1000678-compliant lawful intercept capture, mediation, and delivery interfaces protected by RBAC.
Anycast: How it works
The Cordboard VSS system is fully masterless, with no master site or region. All sites are
identical and interchangeable. Anycast routing automatically pins new calls to the nearest
location, ensuring that media stays low-latency and responsive, and since all sites share
the same signalling IP and sync registrations, inter-site routing is eliminated.
Configuration sync is handled through a realtime database shared by all sites, eliminating
config sync time and ensuring that routing and customer settings changes apply everywhere,
instantly. Atomic config apply and rollback-on-fail ensures that your switch never results
in a customer-facing outage.
