SIP Trunking Providers
SIP trunking (Session Initiation Protocol), is a technology with which you are able to receive and make a voice over IP (VoIP) call, using a broadband connection. With an IP based service there is no need for a fixed telephone line, as this is replaced by using network data connectivity.
How Does SIP Trunking Work?
SIP trunking acts as a replacement for traditional ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) telephone connections.
Traditional ISDN telephone lines use a specific set of communication standards to simultaneously transmit voice and data, through telephone lines and exchanges over a digital line. A standard telephone line sends voice and data over the same telephone line. This enables the user to make calls from a home phone and plug in a broadband router for direct access to the internet using the same port. PSTN telephone lines are operated by national, local or regional telephone network operators. Calls made and received using a PSTN network, are done so by using analogue voice data which is transmitted over a circuit-switched telephone line made of copper wiring. This type of network is operated and owned by a phone services provider.
SIP trunking allows your PBX (Private Branch Exchange) to connect to the PSTN through any form of internet connection; such as broadband, mobile data or ethernet connection. The SIP trunking service providers can connect between one, two or even unlimited channels for businesses, large corporations and contact centres. In comparison to ISDN and PSTN lines, SIP trunking is more flexible in how geographic numbers are used, and you can make long distance, local and international calls as long as you have an internet connection. It is quick to install and provision, and is cost effective and reliable in delivering robust business continuity.
Why Switch to IP Solutions?
Traditional ISDN and PSTN telephone connections have been the known source of connectivity since the early 1980’s; when BT launched ISDN services nationwide. However, with the advancement of technology and innovation of fibre internet and ethernet products, more developed avenues for communications are now possible. Majority of businesses have already switched to IP based solutions, such as VoIP and SIP, offering a more affordable and flexible alternative to ISDN and PSTN inbound and outbound calling.
What Are the Advantages of SIP and VoIP?
- Flexibility: You can be based anywhere in the UK and be able to use your telephone line nationally and internationally without physically being in your office; as long as there is an internet connection.
- Savings: A huge reduction in costs compared to an ISDN or PSTN line; without charges for expensive line rental and cheaper call plans.
- Quick Installation: Connectivity is faster as there is no engineer or installation requirements
- Advanced Features: The ability to integrate with all types of hardware and software, increased control and analytics allows access to an incredible range of new and modern developed features.
