Optimum Voice® SIP Trunking can save your business about 50% over traditional T1-based services. For starters, we charge you only for what you use. And we're flexible -- our VoIP service makes it easy to add and remove lines, so you can scale back costs or ramp up to fit your growing call volume. Plus, you can get up to 100 telephone numbers, and we'll include your first 10 free of charge with your upgrade. And of course, you'll always have access to 24/7 live, local customer service.
