Two Things to consider regarding international numbers

Two Things to consider regarding international numbers

When you want to register an international number there are several ways to achieve that. You can register them via the incumbent provider in the specific country or you can go to a company that already has those connections.

1. Connect to the country specific incumbent provider

Pros: Highest margin on calling minutes and lowest monthly number costs. Own company name visible on number registration.
Cons: Really difficult to get a registrar status in every country.

2. Use a wholesale (PSTN) VoIP terminator (SIP Trunking)

Pros: Really easy to register, and often ready made API’s to connect to your billing engine and PBX.
Cons:  lower margin on calling minutes and higher monthly number costs. Other company name on number registration details.

Here is a list of some those of those, that often provide a whole lot more features than alone numbers.

    In an increasing number of countries number portability is available, so using a wholesale DID provider can be an easy way to kickstart your business. Once you get a bit of traffic volume you can still ‘upgrade’ to carrier status if the business case is feasible. Important things to look at when using wholesale providers or brokers are emergency service calling features and possible national regulations and legal intercept options.

    Great Florian,

    Didn’t know that portability was already this convenient. But when you upgrade to carrier status, don’t you have to port all your numbers? Isn’t that very hard to do?
