In addition, by implementing IP-based trunking services, branch offices can preserve their investments in legacy infrastructure and extend its useful life, while leveraging the IP-based services hosted at headquarters. SIP trunking allows the enterprise to consolidate separate voice and data infrastructures into a single converged network. Moving onto a single platform that handles both voice and data traffic reduces capital expenditure by a huge margin, both initially and for the long term. In addition, SIP trunking opens up new avenues for conferencing and collaboration With SIP trunking and least cost routing, these costs are significantly reduced. Even though International calling rates have significantly come down in the recent years, they are still a significant source of expenses for multinational companies. This leads to high long distance call charges. Consequently, a significant amount of calling traffic exists between these offices as employees collaborate on projects together. With globalization, multinational companies have offices all around the world. SIP Trunking: Benefits for the Enterpriseįor the Enterprise, SIP trunking provides a host of benefits, including the following: SIP trunking can be implemented either with or without replacing the organization's existing voice network equipment. The SIP trunking service allows the enterprise to realize the cost-saving, technological and operational benefits of VoIP when communicating with branch offices as well the outside world. So, SIP trunking is a service offered by an Internet telephony service provider (ITSP) that connects a private business-class phone system-such as a hardware-based private branch exchange (PBX), key system, or software-based iPBX-with a voice-over-IP service network. A traditional trunk is a service offered by the plain old telephone service (POTS) carrier-provider and is based on time division multiplexed (TDM) technology.Ī SIP trunk, in contrast, uses Internet protocol (IP) technology to provide the connection to the outside world. Have you joined the crowd? If you have been contemplating moving towards IP- based telephony supported by such services as SIP trunking, perhaps now is the ideal time to make the leap.įirst off, what do we mean by trunking? With traditional a PBX, the enterprise leases a high-capacity, multi-call phone line-a trunk-that connects the internal phone system to the outside world via the public switched telephone network (PSTN). The migration to SIP-powered IP telephony has taken the world’s businesses by storm as it paves the way toward the new world of Unified Communications. The ubiquitous availability of Internet access has ushered in the era of SIP-based trunking services, which enable enterprises to migrate from dual, physically separate voice and data networks to a converged and consolidated allIP infrastructure. As with its predecessors (HTTP for web browsing or SMTP for email), SIP enables users to engage in integrated communications anywhere and anytime-regardless of the underlying network infrastructures employed. SIP-the acronym stands for session initiation protocol-has emerged as the universal standard for Voice-over-Internet Protocol (VoIP) services. For traditional PBX systems as well as state-of-the-art all-IP telephony implementations, SIP trunking connects today's enterprises to the cost-savings, streamlined operations and rich-featured communication that voice-over-IP offers. SIP Trunking: IP Telephony for the Enterprise SIP-powered telephony is paving the way to the new world of Unified Communications.
