Network

A voice network built to keep calls up

Geo-redundant session border controllers, carrier-diverse routing and a 24/7 NOC that watches quality per destination — so problems are fixed before your agents notice.

Architecture

Redundant at every layer

No single point of failure between your dialer and the terminating operator.

Geo-redundant SBCs

Active-active session border controllers in multiple regions. Register to the nearest; DNS SRV fails over automatically.

Carrier diversity

Multiple upstream paths per destination, each scored on live quality. No dependency on a single interconnect.

In-call-setup failover

Failure codes and quality drops trigger the next path within the same call setup, with CLI rules preserved.

Quality floors

Routing only considers paths above per-destination thresholds for ASR, ACD and PDD — cost comes second.

Secure by default

TLS signalling, SRTP media, IP allow-lists, per-endpoint channel caps and fraud thresholds on high-risk destinations.

24/7 NOC

Engineers on shift around the clock at [email protected]. Incidents and maintenance are posted in the portal.

FAQ

Network questions

Can’t find what you need? Our routing team answers within the hour, around the clock.

How does failover work?

Each destination has an ordered set of carrier paths that already meet the quality floor. If a path returns failure codes or quality drops below thresholds, the next path takes the call within the same setup — and CLI handling rules travel with it.

Do you support encrypted calls?

Yes. Use SIP over TLS on port 5061 and SRTP for media. Encryption is available on all trunks; some downstream carriers decrypt at their edge, as is normal in the PSTN.

How is quality monitored?

We sample ASR, ACD, PDD and NER per destination and per carrier path continuously. Alerts trigger automatic re-ordering of routes and NOC review; you see the same stats per destination in your portal.

What concurrency can I run?

Concurrent channel limits are set per endpoint and raised as your account history grows. Burst capacity for dialers is available on CC routes after review.
