SIP trunking is replacing traditional ISDN & PSTN phone lines and that’s a good thing.
With no connection and other up-front charges, you can start cost-effectively with just a single channel on a monthly contract. Daily and monthly spending limits are integrated as standard and provisioning is easy and instant using our portal or via APIs.
Compatible with any SIP/2.0 PBX, you can even use your existing infrastructure to simplify your migration, then enhance your service further with other cloud services.
How does it work?
SIP trunks work by connecting your existing PBX (or IP-PBX) phone system to the outside world using a data connection (either internet, Ethernet, or IP VPN), without losing the features and services you use every day.
You can use either your existing internet connection, or speak to us about providing a guaranteed QoS-enabled circuit that will support both your SIP and data traffic.
SIP calls can share the same circuit as your data. Applying Quality of Service (QoS) to your connection will mean call quality is optimised.
When adding SIP trunks, your only limitation is the bandwidth of your data circuit. You can add as many channels as you like so long as your data connection is big enough to support it.
SIP Trunking Benefits
By using Voice over Internet Protocol (VoIP) and Session Initiation Protocol (SIP) together, you no longer need separate phone lines, saving you money, consolidating services, and increasing flexibility.
SIP trunk monthly charges are a fraction of equivalent ISDN channel rates. There’s no minimum number requirement, so the savings are significant from the start, often well above 70% over the contract period.
By lowering fixed and recurring costs, plus removing the need for additional equipment, SIP trunking makes a positive impact on a company’s financials. Significant savings can be achieved within six months to a year of switching over.
Unlike traditional PSTN lines, SIP trunking can be scaled as your business grows, or as demand rises and falls throughout the year. This pay-as-you-go model is cost-effective and suited to today’s business approach.
SIP trunks are far more mobile friendly. When you are travelling or working from home, calls can be easily re-routed to mobiles or other numbers, without dialling different numbers, allowing consistent call experiences.
Unlike ISDN where you are limited to 30 channels per circuit, SIP trunks are only limited by the size of your data connection, making it easier and cheaper to grow the number of lines required.
By using data connections to deliver your voice calls, you can now use geographic numbers even when you are away from that location. This improves user mobility and productivity without sacrificing caller access, ensuring responsive services to your callers.
SIP trunks can be provisioned really quickly. Typically taking only a few seconds when using our portal or via API integration.
Because SIP trunks run over your existing data connectivity, there’s no requirement for additional hardware or related installation and maintenance services.
SIP powers unified communications and collaboration too. By adding SIP trunks to your service, you can now integrate your existing Comms with other apps, services and devices that use the IP network to communicate.
It’s a myth that ISDN is better quality than SIP. As long as your data circuit supports quality of service (QoS), you can make sure your calls always get through without degradation. QoS is enabled on all the data circuits we provide to our customers.
Just like a data network, service integrity is possible just by adding additional connections. SIP isn’t tied to a specific line, and will use the best or most available connection.
The service is compatible with SIP/2.0 PBX solutions. In most situations, you can continue to use your existing handsets and PBX without having to replace them. This is great for cloud migration strategies.
