The Smartline SIP Trunk

The Orbtalk Smartline SIP Trunk is a VoIP service that reduces your phone charges by providing access to our unbeatable call rates.

You can add inbound phone numbers to your account from more than 8000 international destinations. After paying a minimal set-up fee to get you connected to the Orbtalk system, every call can then be sent to wherever you are and whichever device you're using - desk handset, mobile, smartphone, PC or tablet.

With a Smartline SIP trunk, there are no roaming charges and call charges remain the same, even when travelling abroad.

Telephone Support Not Included

Please note: Since this is our cheapest, budget product we are unfortunately not able to offer telephone support for this service. For a product that includes our full support package please take a look at our SIP Trunk solution. Alternatively you can learn more about our support service here.


Orbtalk can offer phone numbers in more locations than almost every other VoIP provider globally.

You have a choice of phone numbers from over 8000 destinations worldwide including America, the UK and Europe, Asia and many more. Prices start from as little as £1 per month and £1 setup, and there's no minimum contract terms. New business telephone numbers can easily be purchased via the Orbtalk Portal and will be ready to use within 10 minutes.
