What is SIP Trunking?

SIP trunking refers to the use of a Session Initiation Protocol (SIP) to establish and manage phone connections over the internet between your private branch exchange (PBX) and your SIP Trunk provider’s network infrastructure. These connections create the bridge between your business phones and the Public Switched Telephone Network (PSTN) without the need for costly traditional phone lines.

Are there backup options if our on-site servers go down?

Yes, with our API connections, you can set an automated failover of incoming call routing to alternate phone number destinations.

If your NBN service is also with us, we have options for our customers to purchase a modem/router with built in backup4G mobile data service.
