Finally, there is placing of calls to standard phones. This is where PSTN gateway comes into play.

I suggest when dealing with a larger pipe you consider larger Tier1 providers. You can still get a great price even though it's not as low as some of Tier 2 and Tier 3 companies. You'll also have peace of mind knowing that you have an SLA and company will deliver what you believe you will get. If you're in market of a DS3, communications are vital to your company. Make sure you get both a reliable product and price you're looking for. If you need help finding such a service, consider speaking with broker who is knowledgable of providers available in your area.
