NBN or National Broadband Network is spreading like a trend across Australia. And so the previous technology of ISDN is being converted into IP mode, that is Internet Protocol. The transfer of technology in businesses becomes easier with SIP, or Session Initiation Protocol, a hassle-free process. SIP enables businesses to operate phone services through the internet. It provides mobility and flexibility in working. Chat, video, and voice calls can all be performed over the internet only, removing the old practice of keeping landline phones around. A good example of such a service provider is Telstra, which offers both SIP and Telstra mobile SIM plans. Let’s go through the list of benefits that SIP helps you achieve by changing the way you do business:

1) Easy Setup: This setup is very easy to install and can be done in a few days’ time. It works only on software, so the installation doesn't require wiring or physical devices. SIP Trunk allows businesses to use local area code numbers, which can be used from one or more locations they have.
2) Brilliant ROI: Whenever there is an investment in a business, it takes time to recover it which is called ROI, or Return On Investment. The time could vary from months to years to get your investment back, but in a SIP, the time frame of returns is much lower as the investment itself is low. You can easily compare both bills. A prompt ROI can give you the ability to make better decisions, along with a better work style and low-cost transmissions.
3) Better Quality Calls: Low-quality calls can affect the company’s image, leave a bad impression, or even make the customer go away. Call drop is another way of frustrating customers. SIP overcomes these things by providing a bigger bandwidth and better services all the time. So when the call quality is maintained by SIP, all you need to focus on are customers and vendors. One good example is Telstra Business SIP support, which provides solutions to all SIP-related queries and is available 24x7.
4) Mobility: SIP allows a lot of users to work simultaneously without dropping the quality of calls. And the calls can be attended to or sent from anywhere, unlike the old system where a person needed to be near the phones to attend them. In the event that the employee is moving somewhere, the system allows the calls to be transferred to his mobile phone. This benefits those who are working remotely or travelling between places.
5) International Growth: The usual landline telephone services allow businesses to operate within a limited area. But with SIP, they can scale their businesses to serve clients beyond the national border. With the internet on your side, you can connect to people from other countries, and have customers from all over the world. This removes your limitation to working with clients in the country, and opens doors to expanding businesses to more places. SIP merges your voice and data services into one system, so it's easy to operate and manage people working everywhere. You can expand or reduce the number of users needed.
