Two kinds of exchanges were normally found in the traditional telephone systems. One was the PSTN or Public Switched Telephone Network, and the other was the PBX or Private Branch Exchange. The PSTN exchange catered to the general public who were provided with dedicated telephone lines. The PBX exchanges were used by business firms for communication between the different departments through dedicated departmental lines. In both cases, two persons at two sites could talk to each other over the telephone lines at a time. The interconnection between the PSTN and the PBX exchanges were done through PRI or Prime Rate Interfaces that could be two to ten telephone lines.

Replacing Legacy Systems

The main problem with both the setups was that a huge cost was involved in installing, maintain and repairing the physical components of these systems. Another problem was that communications could break down very easily if any portion of the physical components became faulty. The coming of the Internet threw open huge possibilities of utilizing the data lines to replace the telephone lines of the legacy systems. Till now data lines were being used for transmitting data, text and video only. Developers started creating applications to enable voice transmission over data lines along with video and audio. The facilities provided by Freeswitch SIP Trunking runs on such an application.

Features of Application

The application used in Freeswitch SIP Trunking is open source software that gets regularly updated by the users bringing to the customer newer features. It acts as a PBX exchange and connects to the PSTN exchange through the broadband data network. The companies and business houses have got rid of the huge expense incurred in maintaining their legacy PBX exchanges in one shot. The application not allowed VoIP connectivity but also data, images, texts and every other medium could now be transmitted through the data network.

End of Worries

The continuity in communication ensured by the Freeswitch SIP Trunking application has brought an end to the nightmare of losing business and customers due to a breakdown in communications. Landlines of legacy systems used to restrict the movements of the business owners as they had to remain within accessible distance for taking important business calls. The use of the data network for voice communications allows the business owner to be in any place in the world and still take the calls that are critical to the business. The cheap rates of toll-free numbers helped the businesses maintain easy channels of communication with customers looking for information or services.

Versatility of Application

Scaling the legacy systems was costly because the PRI lines were available in sets of 23. If you wanted to add one extra channel to the existing twenty-three you had to buy a whole new set of twenty-three channels. Removing one channel had the same problem. The channels provided by the Freeswitch SIP Trunking application can be added or removed in singles at any time allowing the businesses to pay for only the channels they use and not for something that is of no use to them at all.
