HUGE cost savings

Reduce monthly communications expenses as your phone calls are transferred over the Internet which costs much less than using direct communication with the PSTN (Public Switched Telephone Network. Whether you choose an unlimited, metered, or high volume plan, rest assured you’ll be saving at least 25% over what traditional phone companies charge.Eliminate the need for expensive TDM (Time-division multiplexing) gateway equipment or POTS (Plain Old Telephone System) lines. No need for expensive voice circuits when you use sip trunking, all your calls are delivered over your broadband connection. Capacity is based on your broadband speeds, which are scaled at a much lower cost than traditional voice circuits.
In most cases your current phone system is VoIP ready, which means there is $0 capital investment to implement sip trunking. In the rare case that your current equipment is not VoIP ready, then expect a minimal capital investment for equipment used to interface sip trunking with your current phone equipment. Depending on your call volume, some or all equipment required is free as part of negotiated service commitments with RateTel.
