Questions about Centrex Systems
How is Centrex different from a cloud PBX?
Both remove on-site PBX hardware. Centrex runs in the operator's voice network; a cloud PBX runs on internet-based platforms with apps for laptops and mobiles.
Can we use our existing desk phones?
Often, yes. We check compatibility during the survey.
Is Centrex suitable for a single office?
Yes, though its advantages are greatest for organisations with several locations.
Can Centrex users work remotely?
Remote options depend on the setup. If remote working is a priority, a cloud PBX may suit better.
Is Centrex Systems available outside Delhi NCR?
Yes. We're based in New Delhi and serve businesses across India, including Mumbai, Bengaluru, Hyderabad, Chennai, Pune, Kolkata and Lucknow, through our carrier and technology partners. Availability is confirmed for each location before you sign.
