SIP Trunking Benefits for the Enterprise Lowered Total Cost of Ownership

For the Enterprise, SIP trunking provides a host of bene-fits, including the following:
1. Lowered Total Cost of Ownership
a. Reduced Long distance call charges
With globalization, multinational companies have offices all around the world. Consequently, a sig-
nificant amount of calling traffic exists between these offices as employees collaborate on projects
together. This leads to high long distance call charges. Even though International calling rates
have significantly come down in the recent years, they are still a significant source of expenses for
multinational companies. With SIP trunking and least cost routing, these costs are significantly
reduced. In addition, SIP trunking opens up new avenues for conferencing and collaboration
b. Reduced Capital Expenditure (CapEx)
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. SIP trunking allows the enterprise to consoli-
date separate voice and data infrastructures into a single converged network. In addition, by imple-
menting IP-based trunking services, branch offices can preserve their investments in legacy infrastruc-
ture and extend its useful life, while leveraging the IP-based services hosted at headquarters.
c. Lower Operational Expenditures (OpEx) 
SIP based trunking allows one converged network to transport data and voice services simultaneously. 
This convergence reduces the overhead required to operate and maintain two disparate systems. 
Moves, adds, and changes (MACs) are much easi- er and cheaper on an IP-based PBX and telephony 
platform. With legacy platforms, difficult configura- tion changes can be cumbersome and costly third- 
party consulting often comes into picture
