Secure and Cost Effective
SIP trunking is a technology that lets you make and receive calls over a data connection instead of a dedicated voice circuit.
By using SIP trunking, your calls are made over your internet connection rather than a traditional phone line. Calls can be prioritised over other internet traffic, making sure you always have a great connection.
The technology allows you to lower your call spend by leveraging your existing voice platforms with a single data connection.
Scalable and Flexible
Ideal for organisations who wish to consolidate rental agreements and costs of traditional phone lines into a more autonomous, scalable, and flexible voice solution.
It enables businesses to scale up quickly and reduce the overall cost when providing new voice services to a company location or deprecating services from an existing location.
SIP trunking can be delivered from a single carrier and provisioned to multiple geographical locations by leveraging existing internet circuits.
Making it easier to manage the billing and procurement of new telephone numbers and for business and service level continuity.

Is There A Limit To How Many Calls I Can Make and Receive Through The SIP Trunk?
The amount of bandwidth dictates both the amount of concurrency and quality throughput.
Can You Provide Disaster Recovery Across Sites In The Event Of A POP Outage?
Calls can be load balanced across multiple sites in an active-active type setup mitigating POP dependency.
Is The SIP Trunk Service Highly Available?
The core network in which the SIP trunk terminates is handled by a Session Border Controller (SBC). Each SBC is part of a cluster which utilises the N+1 methodology i.e., for every SBC there is another one to handle the load if an SBC within the cluster fails.
