How operators use our softphone

01CLECCompetitive Local Exchange Carrier

Differentiation in three weeks, not three quarters

Replace the third-party dialer your subscribers tolerate with a branded softphone they open. Ship it through your own store listings and own the support relationship end to end. Acrobits handles SIP, codecs, and push.

  • Branded build under operator's own developer account
  • Single app replacing multiple third-party dialers
  • Unified support script across iOS, Android, desktop

3 weeksFrom contract to branded app in stores

02MVNOMobile Virtual Network Operator

Added voice to a data-only product without building it

Add voice to a data-only plan without a softphone team or a SIP stack. Subscribers get a branded dialer they can't tell from carrier-built. Pay only for subscribers who register and call.

  • Branded SIP softphone without an in-house softphone team
  • Active-user billing aligned to usage-based subscription model
  • Native dialer experience on subscriber devices, no SIP stack required

$0Billed on dormant SIMs, pay only for subscribers who register and call

Customer story · Telecom

Why a Regional Voice Reseller Stopped Owning the Plumbing

Marco's open-source app had become a second job. He moved to Cloud Softphone, put his customers' CRM and AI tools inside it himself, and turned the app from a cost line into his highest-margin product.

03MULTIBRANDMulti-Brand Operator

Three brands, three store listings, one portal

Run every brand from one Acrobits portal, not one vendor contract per brand. Each keeps its own store listing, branded build, and call-screen identity. Volume discounts apply across the whole portfolio.

  • Multiple store listings from a single portal
  • Sub-branded builds sharing one operational surface
  • Volume discounts applied across the full brand portfolio

3 brands · 3 apps · 1 portalOne operational surface, volume discounts across the portfolio

04LOCATION-SIPUCaaS & Managed SIP Operators

Location context for calls placed through your app

Calls placed through your Acrobits-powered softphone can carry device coordinates in the SIP signaling. Your platform feeds that signal into its own routing, geofencing, or review workflows. Native cellular calls stay outside this path.

  • Device coordinates available at SIP signaling time
  • Location input for operator-managed call policies
  • Scoped to calls placed through the branded softphone

How an MVNO Launched a Branded Calling App in Five Weeks, Not a Year

Talia runs product at a data-only MVNO. An in-house build was $500K to $1M and a permanent mobile team. Instead her team shipped a fully branded calling app in five weeks, with low-balance alerts firing as native badges through the IPC SDK.

05CGNATBandwidth-Constrained & CGNAT-Heavy Operators

Bandwidth-constrained, CGNAT-heavy, and still ringing

Generic dialers tuned for high-bandwidth networks drop registrations on CGNAT-heavy, bandwidth-constrained ones. Scope SRTP, TLS, codecs, and NAT traversal during the POC instead. The app ships tuned for your subscribers, not patched after launch.

  • Transport stack configured for actual field conditions before launch
  • NAT traversal and codec selection scoped during POC
  • Registration stability on networks where generic dialers drop

What You Ship

  • White-label the softphone with your logo, colors, and dialer behavior.
  • Ship to the App Store and Play Store under your own developer account.
  • Subscribers download your app, Acrobits is invisible.

Why operators switch

01

Your open source bill just became a headcount problem

You spent months making the app look right. You'll spend months again on the next iOS or Android release. Open source softphones don't come with vendors who absorb OS changes upstream: the maintenance work shows up on your dev backlog every quarter.

02

Your platform vendor was acquired. Your app is next.

When the softphone you ship today is bundled into someone else's ecosystem tomorrow, your brand becomes a reseller line. Subscribers don't see a migration plan; they see a notice. The operators who move first ship under their own brand before the deadline forces them.

03

Your softphone comes with vendor lock-in

When the softphone is the platform vendor's product, you don't own the subscriber relationship. The vendor's margin grows on your customer. The roadmap, the pricing, and the brand on the device all belong to them.
