SIP Trunks

For companies utilizing our on site VoIP PBX or those wanting to make full use of their already installed IP-PBX, can now not only communicate over IP within the company, but also outside the company. SIP (Session Initiated Protocol) trunks connect your onsite PBX to the traditional PSTN (Public Switched Telephone Network) in this solution. Unlike traditional telephony, where bundles of physical wires were once delivered to a business, SIP trunks allow a company to replace these traditional lines with PSTN connectivity via IP.

SIP Trunks delivered across Harbor’s network allow for Internet like savings without your voice traffic ever travelling across the open Internet. Your calls traverse Harbor’s own private network to our hosted packet based switch then out to the PSTN. Another example of how Harbor provides big carrier solutions combined with personalized local customer service.
 
Forward thinking companies are converting their PRI based phone systems every day by utilizing Harbor SIP Trunks to upgrade their phone service, while lowering the monthly service cost of their voice communications.
