Why SIP trunks?
If you've invested in a PBX that works well, SIP trunks let you keep it while moving calls onto modern, internet-based lines.

- Port your existing business numbers

- TLS encryption on alternate ports; enhanced SIP add-on available

SIP trunks or hosted VoIP?
If your PBX is ageing or you want to stop maintaining hardware, hosted VoIP may suit you better: the phone system lives in the cloud and costs from £6.95 per seat per month ex VAT. Our business team can compare both for your setup.
What you'll need
A SIP-compatible PBX (or an adaptor), and a reliable business internet connection with enough upload capacity for your concurrent calls. OCCTA business broadband and leased lines are built for this.
