Boost Efficiency with SIP Trunking

SIP Trunking

Princeton has been deploying SIP Trunking successfully for its customers for many years. Our access to virtually every SIP Trunking provider enables us to expertly customize a solution for each customer.

SIP (“Session Initiation Protocol”) Trunking is a version of VoIP, specifically designed to make and deliver phone calls using an internet connection instead of a traditional phone line. Comparatively, Hosted PBX, (a PBX in the cloud that is used as a service in place of a premise PBX) is another version of VoIP.

Benefits of SIP Trunking


Leverage your IP PBX: Modern IP PBX / Unified Communications solutions give customers increased productivity, mobility and boosts sales. For example, the Simultaneous Ring feature rings both your office phone and cell phone at the same time, enabling you to answer on either device and never miss a call. Also, with the Voicemail-to-Email feature, you will receive an email with an attached wav file of any voicemail that is left for you on our system.


Flexibility: Easily add channels to your SIP trunk to cope with increased calls. A simple phone call to Princeton Customer Service allows you to add channels, often immediately. Compare that to the delay in having additional lines installed and then having to upgrade your old PBX to handle more lines.


Correct number of channels: With SIP trunks, you can easily choose the correct number of channels that you need. Compare that to using ISDN/T1, which often requires adding either 15 or 30 lines, expensive extra capacity.
