What is SIP Trunking?

Date April 13th 2017 by in Category Telecommunications

In 2015 Gavin Patterson CEO, BT Group, announced BT's plan to migrate all customers to an IP network by 2025, eventually switching off PSTN and ISDN services.  But what does this really mean for your business? 

Your company’s telecoms system plays a crucial role in business performance and a lot of business owners invest time, money and resources on ensuring that their IT systems are robust, in order to maintain business continuity. Few appreciate that a reliable and resilient telecoms system is just as important to ensuring business stability and minimising the impact any outage can have on your bottom line. 

To stay competitive, today's businesses require more than independent phone and data lines, therefore businesses are now opting for SIP Trunking and enjoy the additional benefits it brings.    

What is SIP Trunking?

SIP (Session Initiation Protocol) is the basis of SIP Trunking which works with VoIP phone systems (Voice Over Internet Protocol) to deliver a telephone service and unified communications via the internet, eliminating the physical connection to a phone company via traditional lines such as PSTN and ISDN.

What are the benefits of SIP Trunking?

Many of our clients are already enjoying the benefits of SIP Trunking, which include:

  • Cost effective communications - Instead of operating and maintaining both data and telephone voice networks, it will all be on one network. Call charges can be reduced including international and free calls between multiple sites and offices on the same network, potentially generating a sizable return on investment.
  • Scalable and flexible - It is easy to scale up or down depending on your business requirements. There are no geographic location requirements for phone numbers as the phone number is attached to an IP address rather than a physical line. This allows you to call from anywhere but will display as a local call. All numbers are portable.
  • Simple system management – Reduces multiple phone lines to a single point of entry, IT costs and the maintenance of those lines. Software features make SIP more useful, and companies can implement their phone service in a creative way to make the most of their customer service.
  • Enhanced security and data protection - It is crucial to maintain security both within a LAN and Wide Area Network (WAN) and make sure firewalls are in place
  • Improved operations - SIP allows employees to operate effectively outside the remit of the home phone system and can connect employees both nationally and internationally.
  • Disaster recovery – SIP trunks are more reliable and easier to fix if at some point there is fault with your network. Never miss a call, built in technology automatically allows call to be rerouted to a secondary calling route or to a phone number of your choice, ensuring your business is always contactable (No more waiting for BT Openreach).
  • Quality of service (QoS) – This prioritises your voice traffic and ensures that your phone calls are going to get the bandwidth needed, regardless of what else is happening on the network. Enhanced quality over traditional lines guarantees crystal clear calls.
