What Are SIP Trunks?
Thanks to digital communication channels, SIP Trunks have made physical phone lines obsolete. Instead of expensive ISDN configurations and analog cabling, SIP Trunks utilize Session Initiation Protocol (SIP) for digitized voice, video, and message transmission over the internet. SIP Trunks are exceedingly economical and flexible for businesses needing scalable phone systems.
To better understand, a SIP trunk is a virtual pipe that connects your business phone system PBX to the cloud. Whether your business is handling international sales calls, internal communication and collaboration, or customer service, SIP trunks provide a simple and smart solution to communication overload without clogging up your systems.
How SIP Trunks Differ From Analog and ISDN Lines?
The conventional phone lines, like ISDN or analog, depend on physical connections. The capacity of each line is constrained, and scaling necessitates expensive hardware installations. Additionally, analog systems are less effective in contemporary workplaces due to their lack of sophisticated features like video calling and CRM tool integration.
SIP trunks, on the other hand, are highly scalable and internet-based. You don’t need to dig trenches or install new hardware to add new lines; all you need to do is update your provider’s settings. Additionally, they facilitate unified communication, which enables companies to manage video conferences, calls, and messages all from one location.
