Value vs Premium
From VoIP.ms Wiki
When it comes to Termination, VoIP.ms offers two different routes, Value and Premium. As they are different routes, they also offer different qualities for the service and different rates.
Value
Value route offers some of the greatest rates you can find to place calls to Canada and US. Starting as low as $0.0052 (that's right, half a cent) for Canada and $0.0105 for calls to US. This is a very good option if you are looking for the best wholesale rate to pay or to offer in case you are a Reseller, while keeping a very good level of quality and reliability.
Premium
The premium route to call Canada and US has a flat rate of $0.0125 per minute, that is for all Canada and US. VoIP.ms uses Tier-1 termination carriers for this route. While this route might have a higher rate per minute, you will find yourself always calling with the same level of quality and reliability.
This route is strongly suggested if you are an exigent customer willing to pay a little more for assured quality on your termination calls. Still the rate is just a little above the cent.
It is also important to note, that features like DTMF, DISA, callback and Caller ID can only be guaranteed while using Premium route. Even when value could still deliver good results at a time, Premium route will always provide a better result regarding. Its suggested to switch to Premium route if you experience any kind of issue related.
All new accounts are set on the Value route by default, for both US/Canada termination and International termination.
