The white-label softphone your customers think you built
Spanvox is a native softphone for iOS, Android, Windows and Mac, shipped under your brand and your app store accounts, and bridged to the PBX you already run. No SIP trunks. No dialplan changes. Push that actually wakes the app.
- Under your brand
- No SIP trunks
- Push that wakes
- BYOD SIP
- Multi-tenant
Sold under your brand, in your store accounts
Most white-label softphones stop at a logo swap. Spanvox goes to the root: the app ships under your Apple Developer account and Google Play listing, with your bundle id, your reviews and your own APNs and FCM push identity. To the PBX behind it, Spanvox is just a registered softphone, so your switch, numbers and dialplan never change.
- Your app store accounts
- Your Apple Developer + Google Play, your bundle id and reviews
- Your push identity
- Your own APNs and FCM credentials on every notification
- Your domains
- Per-tenant SIP domains or your own custom domain
- Your PBX, untouched
- We register like a softphone, no trunk or dialplan change
A complete softphone platform, white-labelled
The hard parts of mobile VoIP, push, NAT, multi-tenancy and provisioning, shipped as one platform under your name.
Sold under your brand
Your logo, colours, name and languages. Ships under your Apple Developer account and Google Play listing, with your own APNs and FCM push identity. Customers only ever see you.
No trunks, no dialplan changes
Spanvox registers to your PBX as an ordinary SIP softphone. There is no trunk to provision, no dialplan to rewrite and no firewall port to open.
Push that actually wakes
A server-side registration plus APNs/FCM push wakes the app and rings through CallKit on iOS and ConnectionService on Android, even when it is asleep or killed.
Multi-tenant from day one
Per-tenant SIP domains or your own custom domain keep every customer cleanly isolated. One platform, unlimited brands.
BYOD SIP, not just our app
Register desk phones, ATAs and third-party SIP softphones with standard digest auth, alongside your branded app, on the same account.
Works behind firewalls, encrypted
Calls reach Spanvox over 443 with TURN on an anycast edge. If a device can browse HTTPS, it can call. TLS signalling and SRTP media end to end.
API-first provisioning
Create tenants, endpoints and credentials over a clean, idempotent REST API, with signed webhooks and CDRs for billing and analytics.
Launch in days, not a six-month build
The platform, push and bridge are already built. Provision a tenant, brand the app and ship, instead of funding a multi-quarter custom project.
White-label softphone questions
What is a white-label softphone?
A softphone app published under your own brand, name, logo and app store accounts, while a provider runs the calling platform behind it. With Spanvox it ships under your Apple Developer and Google Play accounts and your APNs/FCM push identity, so customers only ever see you.
Does it work with my existing PBX?
Yes. Spanvox registers to your PBX as an ordinary SIP softphone, so it bridges to Asterisk, FreePBX, FreeSWITCH, 3CX, BroadWorks or anything that speaks SIP. There are no SIP trunks to add, no dialplan to edit and no firewall ports to open.
Can I publish it under my own Apple and Google accounts?
Yes. The app ships under your Apple Developer account and Google Play listing, with your bundle id, name and reviews, plus your own APNs and FCM credentials. That is a deeper sovereignty model than most white-label vendors offer.
Is it multi-tenant?
Yes. Spanvox is multi-tenant from day one, with per-tenant SIP domains or your own custom domain so every customer is cleanly isolated. One platform, unlimited brands.
Will incoming calls ring when the app is closed?
Yes. Spanvox holds an upstream registration server-side and uses APNs/FCM push to wake the app, ringing through CallKit on iOS and ConnectionService on Android even when the app is asleep or killed.
How long does it take to launch?
Days, not months. Because the platform, push and bridge are already built, you provision a tenant, brand the app and ship under your store accounts rather than funding a multi-quarter custom build.
How is it priced?
Start free in a sandbox on one SIP domain, move to a per-seat Growth tier when you go live, and Enterprise for dedicated capacity and SLAs. The same metered model as the rest of Spanvox.
