Session Initiation Protocol is a technology that allows users to gain direct access to Internet Telephone Service Providers, or ITSPs. This technology allows a business to extend their IP or ViOP capabilities without the need of accessing the IP-PSTN gateway, providing many benefits to the business using the service, including:
Less expense in operation, maintenance and upgrades
Extended and cheaper long distance capabilities
Substantial savings and ROI
Session Initiation Protocol trunking is a term that describes the use of such technology in every day business settings. A trunking system connects office communications servers directly to an ITSP using the existing IP address. The “SIP” is the technology, the “trunk” is a dedicated physical line that connects the communication switching equipment. This single line concept eliminates the need for complicated and redundant phone line configurations and equipment.
Aside from great savings on long-distance calling services, this technology can also be used for multimedia conferencing, gaming, instant messaging and other real-time, Internet-based activities that are able to use the line.
Can Your Business Benefit From Session Initiation Protocol?
Since the system completely eliminates the necessity of using publicly switched telephone networks and makes the IP and ViOP completely Internet-based, they make a lot of sense from both a logistical and a financial standpoint.
As mentioned before, since the line doesn’t switch through the public phone system, long distance phone charges are virtually a thing of the past. That’s a big boon in an increasingly global corporate world. Some of the other benefits include:
Streamlined, simplified communications
A single network providing services
Less expense buying and maintaining equipment, such as extensive phone line blocks and PRI subscription fees
Extended capabilities and services, with little or no additional cost
This type of system is easy to connect, since it can share a line and bandwidth with your existing IP service. You simple need two network adaptors, an internal interface and an external interface.
There are three types of trunking system connections, each with their own benefits:
1. A dedicated line, with no other traffic. This is the most costly, but fastest and most secure connection type.
2. A dedicated line, with other traffic. It’s secure and doesn’t require a VPN, but excessive IP traffic can interfere with the ViOP.
3. Public, Internet-based connection. This is the least expensive option, but it’s also the least secure and it requires a VPN to operate.
