A managed platform, not just an app
The bridge model
Spanvox registers to your PBX like a softphone, so there is no trunk, no dialplan edit and no firewall change. You turn on a service, not wire up a backend.
Your own dev accounts
Apps ship under your Apple Developer and Google Play accounts with your own APNs and FCM identity, so the app and its push are entirely yours.
Push, explained
Reliable ringing is server-side registration plus VoIP push through CallKit and ConnectionService, an architecture we describe, not just assert.
BYOD SIP
Register desk phones, ATAs and third-party SIP clients alongside the branded app, on the same account.
API-first, multi-tenant
An idempotent REST API with webhooks and CDRs to provision tenants and endpoints, built for automation, not clicks.
Carrier-grade & transparent
Redundant nodes, GeoDNS and a 24/7 NOC behind the platform, with a free sandbox and per-seat pricing instead of a demo wall.
Carrier-grade under the hood, watched around the clock
The parts that decide whether you can build a business on us: a globally redundant network, real security, and a team that never sleeps. Serious infrastructure for serious operators.
Globally redundant node pool
Registrations and calls run on a pool of redundant nodes across regions, on an anycast backbone. There is no single point of failure: if a node degrades, traffic shifts the same second.
GeoDNS routing & failover
GeoDNS steers every device to the nearest healthy node and reroutes automatically on failure, so latency stays low and outages stay invisible to your customers.
VoIP security, end to end
TLS and WSS signalling, SRTP and DTLS media, terminated on hardened Session Border Controllers. Credentials are encrypted at rest and never exposed to the device.
Toll-fraud protection
Per-endpoint concurrency caps, registration rate-limiting and automatic IP banning contain abuse before it ever reaches a bill, the number-one worry for any ITSP.
Observability as standard
A real-time view of every registration leg, live device, call and CDR with MOS scoring. It ships with the platform, not as a paid add-on.
24/7 NOC
A network operations centre watches the platform around the clock, with proactive response, so problems are caught and fixed before your customers ever feel them.
Bria alternative, answered
What is the best alternative to Bria for service providers?
Providers who want a no-trunk bridge to an existing PBX, apps under their own developer accounts, BYOD SIP and a multi-tenant API often choose Spanvox. Bria is a strong softphone, but more of a client you wrap a backend around.
How is Spanvox different from Bria?
Spanvox bridges to your PBX by registering like a softphone, with no trunk or dialplan change, ships under your own Apple/Google and APNs/FCM identity, supports BYOD SIP endpoints, and provisions through an idempotent API, all on a carrier-grade platform run for you.
Can I ship the apps under my own developer accounts?
Yes. Apps ship under your Apple Developer and Google Play accounts with your own APNs and FCM push credentials, so the app and its notifications are fully yours.
Will my calls ring reliably?
Yes. Spanvox holds the upstream registration server-side and wakes the app with APNs/FCM through CallKit and ConnectionService, so calls ring even when the app is asleep.
Can I migrate from Bria to Spanvox?
Yes. Because Spanvox registers to your existing PBX, you can stand up a branded app and BYOD endpoints in parallel and move tenants over without re-architecting your PBX or carrier setup.
When might Bria be the better fit?
If you want a mature, feature-rich desktop and mobile softphone client and you operate your own SIP backend or use Bria’s provider platform, Bria is an excellent, established choice. Spanvox is for providers who want the whole bridge, push and multi-tenant platform run for them under their brand.
