SIP Trunking is a service that allows you to connect via Session Initiation Protocol to an Internet Telephony Service Provider’s network. In simple terms, this means that you can use this service to send and receive phone calls across the internet.
The trunk or connection to the provider’s network can be tailored to your specific needs.
It can have a limit on the number of calls that can be made at the same time. This is generally known as channel usage and this forms the basis of how the service is billed. Each channel is charged at a cost per month. What differs from traditional telephony is the ability to increase and decrease this without having the penalty of always paying for the highest amount. The service can be set up to allow for national calls only, or for national and international together, in fact, you can choose to either allow or disallow calls to any worldwide destination.
By utilising your existing PBX or IP infrastructure and purchasing the small amount of equipment required, companies can save over 40% on their legacy business telephony system.
SIP trunks can be created on the day and can be deployed by the client in a very short timescale, as opposed to traditional analogue and digital solutions, which can take anything from seven days to multiple months.
SIP trunking allows you to remove the restriction of being tied to your local exchange area and the numbers that are provided within that area. You can have numbers from London, Birmingham or Manchester all sent to your office located anywhere in the country.
SIP trunking gives you the freedom to pick and choose your own IP PBX. Our service is proven to work on most popular IP PBX models via our simple registration method.
By using SIP trunking with Packnet, you pay for how many concurrent calls your business requires, not how many extensions.
