SIP Trunking: voice and data over a single line

Why choose SIP Trunking for your business phone system?

Zen service and expertise

We're an award-winning provider with a host of industry accreditations and qualifications, using our own infrastructure and highly resilient network.

Business continuity

Should you be forced to close an office, SIP trunks can ensure that your calls will be automatically and seamlessly re-routed elsewhere.

On-demand scalability

SIP trunks give you the flexibility to scale your service up or down on demand. You’ll have enough capacity at peak times, and won’t be paying for unused service during quieter periods.

ITSPA member

Zen is a member of the Internet Telephony Service Providers’ Association (ITSPA), and we recommend that customers follow ITSPA’s guidelines for the safe and secure operation of VoIP (Voice over Internet Protocol) services.

ZEN CLOUD

A modern business communications system

SIP trunking is a fully featured, cost effective, proven choice for voice communication, an ideal alternative to traditional voice. Delivered exclusively over our connectivity products (including broadband and leased line), and carried across our highly resilient network, you can be assured of exceptional quality of service.

The benefits of SIP trunking also include optimisation for disaster recovery and business continuity planning. Should your business be forced to close an office, calls can be automatically re-routed to another location of your choice, allowing for business as usual even in the most trying of circumstances.

Using IP PBX from a SIP Trunking provider instead of traditional copper phone lines means less reliance on the PSTN, which is now a legacy technology, and a more dependable voice service.
