Frequently asked questions
Can we keep our current phone numbers?
Yes. Your numbers are kept through a SIP trunk or gateways for analogue lines. The migration has no downtime: the old system and the new one run side by side during the switch.
How much does an IP phone system cost?
The price mainly depends on the number of extensions and the starting point (existing system or new installation). Send us your number of extensions on WhatsApp or by phone and we will reply with a costed quote.
Do we need a new network for IP telephony?
Not necessarily. Voice runs over your existing network if the switches are suitable (PoE, voice VLAN, QoS). We check this during the free audit and tell you exactly what needs to change.
Is IP telephony suitable for a call center?
Yes. Queues, IVR, call recording, statistics and real-time supervision are available, from a few agents to larger teams.
