What is Holiday Numbers?

Holiday Numbers Voice-over-IP (VoIP) is the method of using your Internet connection (normally broadband, 3G, 3G+ or 4G) to carry voice calls, instead of using your regular telephone line.

Holiday Numbers integrates all of these with great rates, convenience and flexibility. Best of all, Holiday Numbers offers value added services at no extra cost, and pay-as-you go for chargeable calls. Only calls to the PSTN numbers are chargeable. Incoming calls and all outgoing calls to other VoIP users are free of charge – so get your friends and colleagues all signed up too! You can forward your calls to Skype account, Google or other compatible SIP services.

Holiday Numbers can allocate PSTN phone numbers in Europe, America (South, Central and North), Australia, Asia and Africa for incoming calls/ faxes. Holiday Numbers is, however, available to anyone anywhere in the world. You’re welcome to join and use Holiday Numbers from anywhere!

What do I need to use Holiday Numbers?
You need broadband or other high-speed Internet connection. VoIP will also work over ISDN, and even analogue (dial-up) Internet connections, though not very good. A means of making the voice calls, you can use Holiday Numbers with any SIP compatible hardware, for example a router with VoIP phone ports (e.g. DrayTek Vigor, Linksys, Grandstream, Cisco series), an Analogue Phone Adaptor, a standalone SIP phone or Softphone on your PC.

What if I don’t have broadband access?
If you don’t have broadband, or you’re away from your broadband line, you can still take advantage of Holiday Numbers low calling rates. Once you have a Holiday Numbers account, you can dial one of our Portal Local Access Numbers for the country where you reside and make calls to any destination at your normal Holiday Numbers rates, using your pre-paid credit. You can also pick up your voicemail from your email or any phone worldwide by dialling our.

Share your prepaid phone call credit with friends and family so they can say goodbye to phone cards forever!! Note: PINLESS feature may not work for every International access number.


SMS / WEB Callback.

For the SMS callback; A user will initiate a call by sending a text to our Callback server which will include both the number initiating the call (A) and the destination (B) number in the text message. Thus the call can be connected immediately, and the user does not have to enter this information in the IVR.  No more consumption of your call credit, no downloading of app.  More…

Worldwide Access.

Whether you take a short trip or extended time away, use your Holiday Numbers account with any broadband Internet connection(3G, 4G, or WiFi). When staying at a hotel or with friends and family you can make and receive calls using your Internet telephone, telephone adaptor or a “softphone” and a headset connected to any computer. Many phone adaptors and Internet telephones are small enough to travel with and can be connected to any Internat LAN anywhere in the world. Once connected and registered, you will be ready to make and receive calls as needed.

SIP Provider. 

Your SIP device e.g. VoIP-enabled router/ adaptor, or softphone logs into the Holiday Numbers SIP Server to register it online. You can then receive VoIP calls from any other compatible user or PSTN if you have a DID number alocated to your account.

SIP-to-SIP VoIP calls.

You can dial any other Holiday Numbers user just by dialling their Holiday Numbers user ID on your VoIP device. The call is, of course, completely free of charge. Holiday Numbers will allocate you a real telephone number (DID) so that any person on the PSTN (a regular phone line or mobile phone) can call you. This is routed through to your VoIP device or softphone so that you can receive the call. That’s a real phone number to receive calls on.

VoIP-to-PSTN Calls. 

In this case, the user with a SIP device lifts his handset and dials a PSTN telephones number. The call is then passed to the Holiday Numbers gateway, which then connects the SIP user to the remote PSTN number. The cost of the call is deducted from the user’s pre-paid Holiday Numbers calling credit. You can check your current credit and call history on the web site at any time when you login to your account.

Use it from landlines, mobiles and payphones for worldwide calling.


Callers can leave a message when you don’t answer a call, out of office hour, or when you are busy. The message is then emailed to you as a sound file which you can listen to from anywhere in the world! This extra service is can be activated free of charge on your account.

Each location still has it’s own Holiday Numbers account but can share the same incoming phone number.
