Wholesale VoIP

We offer quality-focussed, competitive SIP termination over our interconnects with national and international carriers allowing you to offer reliable voice to your customers.

SIP Termination

There are three service tiers to suit different customer requirements. These offer different functionality as well as pricing. Our Gold A-Z is by far the most popular and represents premium stable termination ideally suited to being the sole route in service.

You can select the desired service tier dynamially on a per-call basis simply by using a prefix on the dialled number.

Compare our pricing to your most popular destinations; enter a number to the right to view the current rates to this destination in your preferred currency. This is also a feature of our api

api

Our advanced API allows you to create, provision and configure outbound SIP trunks for your, or your customers', use as well as providing real-time call statistics including calls in progress, current call spend and a simple lightweight query to determine the rate for a call before it's placed - ideal for use with your own LCR.

Managed Termination and Quality Assurance

In all cases we manage the routes in service to optimise performance and quality for customers. We respond very quickly to issues we identify or customer reports and on Gold and Platinum service levels have multiple redundant routes to both tolerate failures and to enable us to pro-actively withdraw sub-optimal routes from use.

Simple Pre-Paid Billing

Our termination operates on an exclusively prepaid basis with billing in US Dollars, British Pounds and Euros. This gives you security against fraudulent traffic as your exposure is limited to your prepay balance, and it means your set-up is not delayed with credit checks and references. Simwood has been around since 1997, is debt free and will return any unused prepay balance right away if you cease dealing with us.
