Why are Businesses Rapidly Employing PBX SIP Trunking Services?

Keeping up with the positive changes in the industry is the key to a successful business. The popularity of Session Initiation Protocol SIP Trunking is growing and there are more and more companies employing PBX SIP trunking services for their businesses. The advantages of flexibility and the lower communication costs are too hard to miss out on, and nearly 70% of IT decision makers have implemented SIP trunking. Here, we’ll discuss this rapid growth of SIP trunking and its importance in the corporate sector.

What is SIP Trunking?

The traditional telephone works through the Public Switched Telephone Network (PSTN) also known, quite appropriately, as Plain Old Telephone Service (POTS). SIP trunking allows the communications to move from the analog lines to the virtual SIP trunks. Since SIP trunking is internet-based and does not employ physical communication lines, the cost of the service is considerably low.

What is PBX?

Private Branch Exchange (PBX) provides internal communication in a business by connecting telephone extensions to the PSTN. An IP PBX is the virtual version and it exists as both hardware and software, providing the following features:

• Call recording

• Find me/follow me

• Least-cost routing/MPLS call routing

• Unified communications/unified messaging

• Voicemail transcription (speech to text)

• VoIP phone/soft phone connectivity

Why PBX SIP Trunking?

All major telecom vendors are in the process of phasing out the old PSTN functionality, and are moving towards IP. By the year 2018, Verizon will have phased out its U.S. ISDN (it stopped taking orders for ISDN service in Northeast from May 18, 2013). By 2017, the huge telecom providers such as KPN, BT, Telecom Italia, France Telecom, and Deutsche Telekom will no longer be offering ISDN services. In addition to this, the ISDN lines in UK have dropped to 3 million from the 4.7 million mark in 2007. ISDN is on the way out, and SIP trunking is settling its roots in the communication sector steadily. Businesses think years ahead, and the fact that ISDN will become obsolete in the years to come is one of the major reasons of the conversion. However, that is not all.

Benefits of PBX SIP Trunking to Businesses

Lower Costs

As we have mentioned above, the SIP trunk price is significantly lower than its analog alternative. However, the SIP trunking implementation costs may vary depending on the nature of your existing PBX. If you have the traditional PBX, you would need to purchase (or rent) a VoIP gateway in order to connect it to the cloud. On the other hand, if you have an IP PBX, you won’t need to make these additional purchases and will only need to pay the PBX SIP trunking service for the channels and minutes that you use.

Flexibility

In times of a higher call load, you can simply add channels to your SIP trunk to distribute the load. Unlike ISDN/T1, you can add either one, or your own specified number of channels, and don’t need to buy more than what you need.

Improved Customer Service

With a PBX SIP trunking service, you have the access to more international and geographic numbers than you do with the old PSTN. You can simply add the required numbers on your SIP and terminate them on your VoIP PBX. This way, you can provide your customers with a chance to call you from local numbers.

The rapid growth of SIP trunking is a testament to its effectiveness, and more and more IT departments are making the choice of converting to PBX SIP trunking, to improve both the communication within the business as well as the customer service.
