Intermedia SIP Trunking
Modernizing your on-premise business phone system with SIP Trunks allows you to increase flexibility while saving on your telephony costs. Modernize an existing phone system or save enough to justify a new phone system. Most newer phone systems are compatible with SIP Trunking with no extra equipment. Our Partners work in tandem to help with all setup and migration tasks. Save money with reduced long-distance, toll-free, and international calling rates. Leverage Intermedia's enterprise-grade datacenters to protect against local outages. With the phone company, customers typically pay on a per-line basis for physical phone lines that originate in their central office. These phone lines are costly. Customers invest a lot when they initially deploy them, and it's very expensive to add more to accommodate growth. But with SIP Trunking, phone calls are routed over the internet. And this makes all the difference.
