Why Evolved Voice over Public Internet?

Seamless integration

EVoPI enables you to switch to internet calling without any disruption or downtime.

Save money

IP voice solutions can offer savings of as much as 50% versus traditional phone services.*

Adaptable

You can add or remove new virtual lines and services as required, making EVoPI highly scalable.

Open to all

Any public sector organisation can use EVoPI, not just those with Vodafone internet connections.

Switch to IP voice without the fuss

Evolved Voice over Public Internet replaces traditional copper telephone and ISDN lines with an SIP trunk service that uses internet connections to carry calls between private telephone exchanges (IP PBX) — such as your organisation's switchboard — and the public switched telephone network (PSTN). This means that changing to EVoPI will have zero impact on your internal call handling.

Keep your numbers and stay in control

If you wish, you can port your organisation’s existing numbers to the new IP voice system. You can also maintain call-barring systems to block calls to premium and international numbers or directory enquiry services.

Sophisticated call handling and features

Evolved Voice over Public Internet supports direct dial-in (DDI), enabling staff to receive data, voice and video calls directly to their desktop. Caller number identification (CLIP), suppression of outgoing numbers (CLIR) and presentation numbers are all also included as standard, ensuring that your operation can continue to function in the usual way.
