Why buy from Call On Cloud
Do we have to configure the devices ourselves?
No. Every unit is configured for your Cloud PBX before delivery — connect the LAN cable and it is ready to use.
Can we keep our existing PBX?
Yes, if it supports SIP. We verify compatibility before quoting, and if it does not, we propose an option that keeps your existing numbers.
What does support look like after installation?
Our local team looks after the system for its whole life — extra configuration, moving extensions, and on-site troubleshooting.
Is bulk pricing different from the listed price?
Yes. Listed prices are per unit at typical quantities. Tell us the quantity in your quote request and we will price it accordingly.
Frequently asked questions
Does the listed price include VAT?
No. Prices shown are per unit before VAT. Your quotation shows the full total clearly.
Is there an extra installation fee?
Installation depends on the number of endpoints and the site. We include the estimate in the same quotation as the hardware — no hidden costs.
How soon do we receive the order?
In-stock models ship within 3–5 business days. For made-to-order models we confirm the delivery date before you place the order.
What happens if a device fails under warranty?
Contact us directly. We coordinate with the service center and can provide a loan unit while yours is being repaired if your system must keep running.
