VoIP (Voice over Internet Protocol) and IP telephony are essentially the same thing — phone calls carried over an internet connection. "IP telephony" is often used in enterprise contexts to describe the broader ecosystem including IP phones, PBX systems and call management platforms. Hosted IP telephony refers specifically to a system where all of this is managed in the cloud by a provider like Telexico.
Not necessarily. If you have existing SIP-compatible IP phones, we may be able to reprovision them. Older analogue phones can sometimes be adapted with an ATA adapter. We assess your current equipment during the free site survey.
Telexico's hosted IP telephony platform runs on enterprise-grade infrastructure with 99.99% uptime SLA. Combined with our Assure X 4G failover, your calls keep working even if your broadband connection goes down.
Yes. Telexico's platform supports call queuing, IVR menus, ring groups, agent dashboards and call recording — everything a call centre or busy office needs. Contact us for a call centre specific quote.
Each simultaneous call uses approximately 100kbps. A 10-user office making 5 calls at once needs just 500kbps — well within even a basic FTTC connection. Full fibre FTTP is recommended for 20+ users or call-intensive environments.
Free site survey. Same-day quotes. Zero downtime migration. Telexico handles everything.
