Custom 3CX Tools for Your Clients, Built on Controvo
Self-service portals, add-ons, custom reports and integrations for the 3CX requests that don’t fit a standard feature, so they stop landing in your ticket queue.
The Requests That Don’t Fit
A front desk needs to change its announcement without calling you. A sales team needs to switch which number shows on outbound calls. An owner wants a report nobody else asks for. None of these justify handing a client the phone system console, and all of them turn into tickets.
We build these as small apps that run on Controvo. Your client gets one simple screen that does one job. They sign in, make the change, and they’re done. They never see the phone system, and you don’t get the ticket.
What We Build
If Controvo can manage it, we can usually put it in front of your client safely.
Client-Facing Apps
Self-service portals for your client’s staff: announcement and night-mode switches, outbound caller ID selectors, office hours overrides.
Custom Reporting
The numbers a specific client needs, in the format they want, without exporting and reworking spreadsheets every month.
Integrations and Fixes
Connect a 3CX workflow to the tools your client already uses, or fix the process that keeps breaking.

Department Announcement Switcher
A partner’s client wanted to change a department’s message whenever plans changed. Their staff now type the new message and switch it on or off themselves, and the change requests stopped reaching the partner.
Outbound Caller ID Switcher
A partner’s client needed their team to show different numbers on outbound calls depending on who they were calling. They now pick the number from one simple screen, with no ticket to the partner.
Why It Works on Controvo
Scoped Access
Each app can reach only what it needs. Every change runs through Controvo’s permissions and lands in the audit log.
Built Fast
Most of what a custom tool needs already exists in Controvo, so building one is mostly designing the screen your client uses. It takes days, not a development project.
Built by the Same Team
You talk directly to the developers who build Controvo, not a reseller or a contractor.
3CX Custom Development FAQs
Can 3CX be customized for a specific client?
Yes. We build small custom tools, add-ons and integrations on Controvo for a partner’s clients, from a single self-service screen to a custom report.
Can I give my client a self-service portal for 3CX?
Yes. Your client gets a simple portal limited to the one or two things they need to change. They never see the 3CX console or Controvo, and every change is permission-checked and audited.
Can staff change a 3CX announcement or office hours without calling their MSP?
Yes. We have built an announcement switcher that lets a client’s staff type a new message and turn it on or off themselves, for holidays, emergencies or after-hours.
Can users choose their outbound caller ID in 3CX?
Yes. We have built a caller ID switcher that lets a client’s team pick which number shows on outbound calls from one screen, without an admin changing settings for them.
Can a custom 3CX portal be white-labeled for my clients?
Your client sees a simple tool built for their job, not Controvo or the phone system. Tell us how you want it presented and we will work with you on it.
How much does custom 3CX development cost?
Custom tools are available to partners whose 3CX systems are on Controvo. There is no separate price list: we evaluate each request by scope and tell you up front what it involves before any work starts.
How long does custom 3CX development take?
Usually days. Most of what a custom tool needs already exists in Controvo, so building one is mostly designing the screen your client uses.
Have a client request that doesn’t fit?
Tell us what your client is asking for. We’ll tell you whether we can build it and what it takes.
