According to one of the findings, there is an estimation that small to medium-sized enterprises are able to gain around 70% of the cost savings in their telephone bills with the support of session initiation protocol i.e. SIP which is a control protocol designed to use along with the IP-based communications. There are various leading technology-based research firms around the world which are estimating the use of SIP in near future. According to one of their findings, it is estimated that nearly half of the American businesses will opt for SIP trunking by the end of 2015. These findings are of no surprise as when we see the price benefits and cost savings which SIP brings along with it.

All the small and medium enterprises which are majorly concerned with the cost savings should consider these three points:

1. Decreased telecom charges:
With the conventional telephony, long distance and toll-calling can be quite expensive deal. This is more of a concern for all those businesses having multiple locations. Infrastructure maintenance, operational expenses and billing need to be taken into account. In case that business has different branches in different location i.e. provinces or cities the pricing or costs can be quite higher. With the support of a SIP telephone system, the calls are usually executed over an IP based connection and it provides a lot of cost saving benefits to the company.

2. Increased control and modification:

Telephone service bills account for major monthly operational expenses for many of the businesses. Usually, these telephone system often sits idle because agents are waiting for the peak hours. If the business is having multiple locations, then it means that company will pay bills for each location thus increasing the cost of the bills. On the other hand, SIP trunking really helps businesses to experience more control and give them an ability to allocate their bandwidth accordingly. In technical terms, it means that the business will purchase a fixed amount of capacity and then disperse it virtually from a centralized hub whenever a particular office in any location requires it. It is a great help for businesses to manage their bandwidths.

3. Unified Network Solution:
With the help of SIP trunking, a converged or unified network can be created which means that services like data and voice can be used under a single roof. This makes previously used necessary infrastructure as redundant and obsolete. This eventually helps to eradicate a lot of cost associated with that infrastructure. This not only helps in streamlining the entire communication network but also decrease a lot of costs associated with infrastructure and network maintenance.

SIP trunking is one of the best technologies that emerged for businesses and with the support of this service, many businesses can reduce their costs to a great extent and also improve their efficiency and effectiveness as businesses can allocate their bandwidths accordingly with providing superior quality. In future, many of the businesses will opt for SIP trunking.
