By leveraging Intermedia’s powerful enterprise-grade data centers, you can protect your business from local service disruptions. Historically, customers faced charges based on a per-line fee for physical lines from their central office, resulting in considerable financial burdens. The upfront costs were considerable, and the price of expanding with additional lines could be overwhelming. In contrast, SIP Trunking enables voice calls to be sent over the internet, which revolutionizes both the cost structure and the adaptability of business communications. This change not only simplifies operations but also equips companies for enhanced scalability and efficiency in the future, paving the way for even greater advancements in communication technology.
