SIP Trunks

A Wi-Manx SIP trunk uses Voice over IP Technology to connect your business to the Global PSTN over a data connection. You can use a dedicated connection for all of your voice traffic, or converged Voice and Data with quality of service (QoS) to prioritise Voice traffic, ensuring high quality calls. SIP trunks reduce costs, improve resilience and increase scalability.

Our SIP trunking solution is a cost-effective, alternative to traditional business telephony. It dramatically increases your business flexibility and scalability and ensures you don’t get stuck with outdated fixed technology.

Using SIP trunks, businesses can replace their traditional voice services and transition to a more cost-effective solution
