According to the recent surveys the growth of SIP trunking deployment has reached 24.3 million trunks in 2013 from 8.5 million trunks in 2009. Enterprises are expanding their business communication services by using Session initiation Protocol Trunking which is a low cost alternative for legacy phone systems.
SIP Trunking technology is actually a service delivered by an Internet Telephony Service Provider (ITSP) that enables small and mid-sized businesses to gain a competitive telephony service against large competitors at low costs. More enterprise people are being convinced that IP-based networks will meet their needs, which lead to significant growth in SIP trunking deployment over the next three years.

It also helps to connect remote employees with central offices via VoIP.
Due to the excellent flexibility and scalability of services, SIP trunking will likely become the foundation for cloud based enhanced services in the coming years. It has been proven to greatly increase flexibility and significantly reduce the provisioning times. It’s a technology that can grow along with the business while providing an impressive range of Internet telephony services. It provides provisions for expanding business communications by maintaining continuity.
When compared with traditional TDM circuits SIP trunks can provide an average of 50 to 70 % cost savings. Savings is the best reason behind the adoption of SIP trunking technology. Instead of multiple TDM lines, SIP trunks make use of a single IP connection to connect all the enterprises voice traffic to service provider’s network. SIP enables the enterprises to buy only the number of extensions actually needed rather than buying lines as bundles of 23. Customers can also expect cost saving by reducing the required hardware resources and copper circuits at corporate sites.
