Ask a Telecoms Consultant: What are the Benefits of SIP Trunking?

Telecoms Consultant

Any telecoms consultant will tell you that SIP trunking in the cloud has two key benefits: simplicity and saving.


The positioning of VoIP as the modern primary telecommunications technology has granted many organisations both financial savings and the utilisation of a range of capabilities. SIP trunking provides cost-effective communication between any location (and its personnel) and an Internet Telephony Services Provider (ITSP). SIP trunking has also come to replace the traditional Public Switched Telephone Network (IP-PSTN).


What are the benefits of SIP trunking?


SIP trunking allows users to:


  • utilise directory assistance services
  • make/receive both local and long-distance calls with ease
  • connect to both landline-based and mobile numbers


Cloud SIP trunking requires little to no upfront investment, as it requires nowhere near the same level of hardware as traditional IP-PSTN gateways. SIP trunking in the cloud has become widely adopted of late due to a number of key benefits. These include:


  1. The elimination of overlapping networks (and their costs). With SIP trunking, one IP-based network provides multiple digital streaming capabilities, negating the need to operate and maintain both data and telephone voice networks. SIP trunking also negates a number of growth-related issues by eliminating the need to add to an organisation’s physical infrastructure in order to accommodate for additional users.
  2. The lack of requirement for local IP-PSTN gateways. This saves on telephony costs, as well as the additional costs associated with upgrading these gateways. Instead of having to purchase hardware to upgrade, for example going from one E1/T1 to two, an organisation can simply increase its internet bandwidth. With SIP trunking there is little to no need to purchase hardware, plus no additional installation or maintenance costs.
  3. The elimination of Basic Rate Interfaces (BRIs) and Primary Rate Interfaces (PRIs). With the elimination of IP-PSTNs, the SIP trunk connects directly to the chosen ITSP, negating the need to pay these subscriptions. The replacement service is less expensive and, in addition, lines do not need to be purchased in pre-defined quantities. Instead, the scalability of SIP trunking means that additional bandwidth can be purchased in much smaller increments and at a lower cost.
  4. Significant savings on the cost of long-distance communications. SIP trunking makes long-distance communications much cheaper, as all calls made through SIP trunking essentially become local calls. Even when an organisation makes an international call, the call is then carried over the internet to a point near the dialled number, at no additional cost.


The lack of initial investment in hardware and installation, plus the lack of ongoing maintenance costs and ease of scalability, means that SIP trunking can provide an organisation with a large ROI on a relatively small investment.
