If you're still…
Running the office phone off a box in the closet.
On the left, what a hardware switchboard costs you. On the right, the same job on a DIDSMS IP PBX with our numbers.
One PBX in a closet — one power cut silences the whole company.
Two servers in hot standby. If one fails the other takes the calls, and nobody redials.
Adding a desk means pulling cable and waiting for the installer.
Add the extension in the admin console. The desk phone or the app picks up its config on its own.
Clients dial one number and get whoever happens to pick up.
Auto attendant greets the call and queues route it to the right desk.
Nobody can prove what was agreed on the phone.
Every line can be recorded, and recordings are searchable by number and time.
Staff on the road only have their personal mobile, so nobody answers as the company.
DIDSMS on mobile and desktop: answer, hold and transfer, with the company number showing.
Scale & models
From 20 extensions to ten thousand.
Pick the model that matches the headcount you have today. Moving up later is a swap, not a rebuild.

What it does
The switchboard features the front desk actually uses.
Grouped by who uses them, not in spec-sheet order.
Extensions, queues and recording are configured in one admin console.
Staff answer on the phone or laptop they already carry, and the caller sees the company number.
If a queue is backing up, you can see it on the board before customers start complaining.
The tunnel service brings remote extensions in without a public IP address.
US numbers
Numbers your customers recognise, and your team answers.
US local and direct-dial numbers: one per employee, a shared line for the front desk, or a toll-free number for marketing.
Find a number
Search by city or area code.
Numbers are released after business verification, and we confirm availability with you before anything is charged.
Main company number
One number customers remember. Calls land on the auto attendant.
Direct-dial per employee
Each person gets a number, so clients skip the switchboard.
Toll-free
An 800-range number for campaigns and support lines.
Integrations
Plugs into your stack. Doesn't ask you to replace it.

Moving over
Bring your current numbers with you.
We file the porting paperwork and schedule the cutover, so the only thing your clients notice is that the calls still get answered.
- 1
Send us the numbers
A list of the numbers and the current carrier is enough to start.
- 2
We check eligibility
Some numbers cannot be ported. You hear about it before the switch date, not on it.
- 3
Pick a cutover window
Out of hours, on a weekend, whenever your phones are quietest.
- 4
Cut over and test
We call each number after the switch and confirm the routing with you.
Reliability
Built so a single failure is not an outage.
Dual-server hot standby
Two units share the load. If one goes down, the other keeps answering.
Geographic redundancy
For multi-site setups, a second location can take over the whole switchboard.
Tunnel service, no public IP
Remote extensions and branch offices connect without exposing your network.
Recording you can retrieve
Calls are recorded on the system, searchable by number and time, and exportable for disputes.
Team & contact
When it breaks, you need someone findable.
Voice downtime is measured in lost calls, not apologies.

Questions
What buyers ask before they switch.
How do I order within 20 extensions?
Order online. We set up the numbers and the extensions with you, and the handsets or apps pick up their config remotely.
What if we need more than 20?
Tell us the headcount, the sites and how you want calls routed. We come back with a model and a quote, usually within a day.
Do we have to buy the equipment?
We supply the PBX pre-configured along with the numbers. You plug it into your network and start taking calls.
Can we keep our existing numbers?
Yes, in most cases. We check porting eligibility first and handle the paperwork and the cutover window.
What do staff answer on?
DIDSMS on their own phone or laptop, a desk IP phone, or both. The caller sees the company number either way.
Do we need a public IP address?
No. The tunnel service lets remote extensions and branch offices connect without exposing your network.
How long does a migration take?
Porting usually runs in weeks, and how long depends on the losing carrier rather than on us. We schedule the cutover once the date is confirmed.
Ready to give the team direct numbers?
Up to 20 extensions you can order online. Beyond that, tell us the headcount and we will come back with a plan.
