VOIP / 3CX

Modern business phone systems powered by 3CX and SIP trunking

Frequently asked questions

Can we keep our existing phone numbers?

Yes. We port your existing numbers to your new SIP trunks. Number porting typically takes 5-10 business days.

Do we need to buy new phones?

Not necessarily. 3CX supports a wide range of IP phones, and the mobile and desktop apps mean many users don't need a physical phone at all. We'll advise on the most cost-effective approach.

Is 3CX cloud or on-premises?

3CX can be deployed in the cloud (hosted by us or on your own cloud account) or on-premises on your own server. We'll recommend the best option based on your requirements.

How does VOIP call quality compare to traditional phones?

With a properly configured network and adequate internet bandwidth, VOIP call quality is equal to or better than traditional PSTN calls. We assess your network before deployment to ensure quality.
