Sixty countries, your numbers kept

Numbers and carriers

Your numbers stay your numbers.

A telephone number is an address your customers know by heart and your competitors cannot copy. There is no reason for it to belong to your software supplier.

The list of numbers in a Konvoice workspace: each number, the carrier that delivers it, and where it rings.

Your numbers, the carrier that delivers them and where they ring, on one screen.

Three ways to connect

You are not obliged to buy anything from us.

It is an uncomfortable commercial choice and a healthy technical one: a platform that cannot live without its own carrier contract is a platform that has you.

Our numbers

You take numbers from us: geographic in more than 60 countries, non-geographic, freephone, mobile depending on the country. Billed per line, cancellable monthly.

Your numbers, ported

We port your existing numbers to our carrier. You keep them, and you can port them away again the day you leave. Outbound porting is never charged for.

Your contracts, kept

You keep your current carrier and we connect its SIP trunk to Konvoice. You change only the platform — no new telecoms bill, no notice period to serve.

Routing

When a carrier goes down, the call takes the other route.

Konvoice never depends on a single carrier. The routing engine picks the route on every call, following rules you can read and change yourself.

By quality — a carrier whose failure rate climbs is dropped automatically, then retried.
By destination — calls to Morocco go out via the carrier that delivers them best, calls to Belgium via another.
By cost — at equal quality, the cheaper route, itemised on your invoice.
By obligation — some traffic has to stay with a named carrier for regulatory reasons. The rule is explicit and audited.

A call goes out
Konvoice weighs the routes available for that destination, in the order you set.
The first route fails
A 503 from the carrier, or no answer within the allotted time.
Immediate failover
The call goes out on the next route. The caller hears a slightly longer ring, and nothing else.
The failing route is dropped
It is taken out of the selection, probed in the background, and an alert reaches your console.

Two carriers, two routes

The connection

Your numbers should not depend on a single cable.

A number ported to us goes out via two separate carriers, over two separate physical interconnects. That is not a higher-plan option: it is the default configuration, because a single-routed number is not a business number.

Automatic failover — a carrier that stops answering signalling is dropped within seconds.
Your own trunks accepted — if you keep your contract, we connect it and it becomes one more route.
Local emergency exit — on a site with an Edge, an analogue or GSM line remains the last route.
Free outbound porting — the day you leave, your numbers leave with you, at no charge.

Porting

The real timetable, with no sales optimism.

Porting is the one step of a migration whose pace we do not control: it depends on your current carrier and on your country’s regulator.

Step	Who acts	Usual time
Survey of the numbers and eligibility check	Konvoice	1 to 2 days
Porting authority signed	You	Same day
Request filed with the receiving carrier	Konvoice	1 day
Processing by the losing carrier	Your current carrier	10 to 20 working days depending on the country
Porting date confirmed	Both carriers	Agreed with you
Switchover	Konvoice	A window of a few minutes, outside business hours

What we do while you wait Your Konvoice platform is already live on temporary numbers. Your teams are training on it, your rules are configured and tested. On porting day, nothing happens other than your usual numbers arriving on a system everybody already knows.

Emergency calls

The subject nobody likes to raise in a sales meeting.

IP telephony has a real weakness: the emergency service has to know where you are. Here is how we handle it, and what you need to know.

Address attached to the site

Each site declares its physical address. An emergency call from a handset on that site presents that address to the emergency services.

Move detection

A handset plugged into a network other than its own site’s is flagged, and the user is asked to confirm their address before they can call outside.

Local backup route

On a site with an Edge and a local line, emergency numbers go out over that line, including during an internet outage.

What to tell your teams An employee working from home who calls the emergency services from their mobile app must be able to give their address. We supply the poster and the awareness text; no technology replaces that instruction.

A person on the phone in the street at the end of the day, the city behind them.

A number is an address your customers have written down somewhere. Changing it means asking them to correct it.

That is why outbound porting is never charged for

Questions about numbers

Can we keep our incumbent carrier?

Yes. We connect its SIP trunk and Konvoice becomes your phone system without your carrier contract changing. Some companies do it to avoid breaking a term still running, others because their carrier gives them terms no platform will beat.

Does porting cost anything?

Inbound: free, whatever the quantity of numbers. Outbound: also free. We take the view that an exit penalty is a confession.

Can we have a number in a country where we have no office?

Often yes, but not always: some countries require a local presence or proof of address to allocate a geographic number. We check eligibility before billing you anything, country by country.

How many numbers can we attach to one extension?

As many as you need. A department can have one number per language, per campaign or per country, all landing in the same queue, with a different greeting depending on the number dialled.

What about SMS?

Inbound and outbound SMS are available on eligible numbers, with the same carrier abstraction as voice. Coverage depends heavily on the country and we give you the real list before you sign.
