The birth cry of the Internet came about in the U.S. when the Advanced Research Projects Agency Network (ARPANET) delivered the first data packet between two computers in 1969. That very same ARPANET saw the birth of Voice over Internet Protocol (VoIP) when the first data packet of encoded voice was transmitted in 1974. In recent years, the dawning and proliferation of the information age has seen VoIP truly come into its own.
An Innovation in the Data World
From businesses to the home internet connection, relatively inexpensive high speed internet is allowing VoIP to replace traditional telephone services. In all but the most remote rural areas, sufficient internet speeds are now available, prompting consumers to question the need for both telephone and internet services when internet will serve both voice and data functions.
Affordability and Convenience
In the past there has been resistance to innovations such as VoIP due to cost and the dread of having to get a new telephone number. That is no longer the case. VoIP equipment is highly affordable and often is less costly than even an average smartphone. Further, the cost of transmitting a data packet over long distance is hardly more than the cost to send the same data packet across the room, making VoIP more affordable than traditional long distance telephone services.
In the early days, a VoIP call had to go through a third party because telecommunications companies held a certain level of propriety over the connections. Now, VoIP calls go directly to the recipient, bypassing the middleman and keeping costs low.
Changes in FCC laws now allow phone numbers to be transferred from one service to another. The process of making the change takes just moments, and the service provider is usually happy to do the work in order to get new business. The service itself is has yearly costs comparable to regular monthly cellular phone charges.
Services That Are Part of the Package
Most VoIP packages include long distance as just another service provided for a very low single fee if not provided entirely for free. A number of services once considered to be extras were billed as such but are now being provided by VoIP as a standard package. Some of these standard services provided at little to no additional cost include call forwarding, voicemail, and call waiting.
Marrying VoIP to Apps
VoIP is IP-based and highly adaptable with regard to data handling applications. As a result, VoIP telephony systems are capable of previously unheard of functions and new applications are arriving on the scene every day. From screen sharing to faxing to email, the IP-based world is growing and expanding in capabilities at a mind-boggling rate. With the affordability of VoIP services being realized, what was once thought to be a tool for businesses has taken root in the home.
Traditional voice services have had their heyday. Today, developing technology trends are shaping a new future for business communications. Automation, the Internet, mobility, cloud, and more are triggering shifts in new services that meet changing customer demands. Session Initiation Protocol (SIP) Trunking is emerging as not just an option but a compelling choice for the modern business.
Focusing on the benefits
Even as voice converges with text, image, video, desktop, mobility, and social media technologies, many network administrators still fear the unknown. Their priority is to maximize and protect their investment so it’s understandable that many proceed with caution. However, in order to steer their business forward, network managers should consider what could go right.
For instance, SIP Trunking has many benefits if best practices are observed.
- Savings. In an SIP environment, IT managers start realizing savings when they phase out costly infrastructure. SIP Trunking eliminates Primary Rate Interface (PRI) and Integrated Services Digital Network (ISDN) rentals. Businesses can also save costs by using centralized public switched telephone network (PSTN) access. This can eliminate costs for maintenance, operations, and unused services.
- Scalability. SIP eliminates the problem of having too many channels when they are not needed and too few channels when more are needed. It can be scaled up or down on a per-channel basis to suit specific business needs. It also enables businesses to add trunks as demand dictates.
- Flexibility. As a Unified Communications (UC) package, SIP offers significant flexibility with an array of collaborative options. End-users can enjoy web, voice, video conferencing, instant messaging, chat, voice traffic re-routing, and mobility options.
- Reliable disaster recovery. Security and recovery can be major fears. SIP Trunking features reside in the IP provider’s network in multiple sites, not in the customer’s premises. Should a disaster occur, businesses are assured of timely disaster recovery (DR) and business continuity. This allows calls to be redirected to locations not affected by the disaster, ensuring a recipient for each incoming call.
Hurdling the obstacles
While SIP is a versatile technology, moving to an SIP model has its own challenges. The most common one is interoperability issues. Different vendors interpret SIP specifications differently. This can create complications when integrating legacy systems with the SIP provider network. A good provider should re-evaluate the customer’s existing architecture and suggest modifications that can support the new services.
Bandwidth capability is an important consideration for SIP connection. Bandwidth determines the quality of calls. The wrong amount of Internet bandwidth and such issues as latency, packet loss, and jitter can result in echoes, garbled messages, and call disruptions.
Connecting to the Internet exposes any network to security threats. Brute force and Denial of Service (DoS) attacks are common issues that can cause entire networks to crash. Solid firewalls, session border controllers, and other security devices can help ward off such attacks.
For IT executives, transitioning to SIP Trunking is a critical decision. Decision-makers should consider an SIP deployment that can support present business needs and easily adapt to unforeseen collaboration services well into the future.
