More businesses are moving away from inflexible legacy telephone networks and are embracing SIP trunking, which offers reduced costs, improved productivity, centralization, disaster recovery, and the first step to a full unified communications platform.

Securing Your Network with a Dispersed Workforce

SIP trunks were also reported to reclaim 23% of the productivity lost with previous inefficient communications solutions.

SIP is experiencing this surge in popularity as more businesses are migrating to next-generation IP environments with wired and wireless networks.

Furthermore, as many companies are looking to cut costs and increase efficiencies with unified communications, SIP offers them the perfect stepping stone to a fully-fledged UC platform. This is because SIP trunks provide us with the virtual signaling tools needed for this environment.

As we increasingly move towards IP networks, the rise in SIP lines will accelerate.

What is SIP Trunking?

SIP stands for Session Initiation Protocol and is the network communications protocol used to control the flow of voice and fax calls using VoIP, and is effectively the method of transmitting the call.

VoIP stands for “Voice over IP”. IP or “Internet Protocol” is the method by which the digitized voice signal is transmitted over computer networks rather than the more traditional PSTN (Public Switch Telephone Network).

To communicate via your IP PBX to outside the enterprise you need a SIP trunk to connect to the traditional PSTN. SIP and VoIP can be considered as your virtual ISDN lines, but with a higher level of reliability and significantly more flexibility.
