The practice of using the internet to establish voice connections has become quite popular over the last few decades. Session Initiation Protocol Trunking, abbreviated SIP Trunking, is one of the well known voice-over internet protocols (VoIP). VoIP is a system that allows one to make telephone-like connections over computer networks namely the internet. SIP involves connecting the telephone system of a company to a Private Branch Exchange (PBX) via internet servers. It is the most convenient communication solution within large business organizations.
SIP Trunking offers several benefits that give it an edge over traditional phone services. The service is provided by an internet service provider. A Public Switched Telephone Network (PTSN) provider uses physically wired connections. On the contrary, an SIP trunk establishes physically invisible connections over the internet network.
The other advantage is the cost involved. The initial setup is expensive to a company that already has a phone system in place. However, its long term cost benefits justify the initial setup charge. Session Initiation Protocol Trunking offers multiple lines and phone numbers at better rates and shorter contract durations. They also offer higher flexibility in their plans. SIP Trunking networks are easier to regulate and maintain. Not only this, by converting a network to be completely internal it offers the highest level of security needed by a company in the transmission of private and confidential information over the internet.
Common Mistakes and Problems
Moving over to SIP Trunking from a conventional phone system has several advantages and there is no doubt about it. But it also has its share of problems. All these problems boil down either to an issue with the equipment, the internet service provider or the enterprise network. And, at the base of everything, there is poor decision making by the person in-charge.
Shifting over to SIP Trunking is a major process and hence, the deployment must be properly planned. One cannot simply assume that everything is in place and will work fine. The system needs to be monitored regularly. There is need for a strong network, a private branch exchange that is in control of call features and phones and a good connection with the ISP if you want to take full advantage of your IP phone system. There is a need to test voice quality as it has to be perfect. Thus, negligence is among the major mistakes made by people.
The second mistake people make is choosing the wrong service provider for the job. The ISP provider you choose should offer SIP trunk services and must be adept at handling complex telecommunication systems tailored to your business needs. An inexperienced service provider will make you regret your decision of opting for the SIP service.
The third mistake people make with SIP Trunking is not paying attention to security measures. Not installing the required protections will make malicious attacks and theft of services easier. It also results in intermittent audibility and frequently dropped connections. Finally, the choice of cheap hardware is a gross mistake people make and might lead to serious problems. For the best results and services, you should use commercial grade hardware and equipment only.
