Why Do Office Phones Get in the Way?
Older phone systems were built for one building, not for scattered teams and data that has to connect.
Office Phones Are Not Connected to the CRM
Incoming calls show only a number with no context, so the team hunts for customer records while already talking.
Extensions Are Hard for Remote Teams
Extensions are tied to a desk phone in the office, so anyone working elsewhere cannot take calls as usual.
PBX Hardware Is Expensive to Maintain
Physical equipment demands regular maintenance and replacement when it breaks, yet its capacity is slow to expand.
Office Phones That Follow Wherever Your Team Works
Four IP PBX features that make an office phone system lighter and better connected.

Questions About Barantum IP PBX
An IP PBX is an office phone system that runs over the internet rather than through a physical switchboard. Extensions, call routing, and transfers are all configured in software, so it works in the office and away from it.
A traditional PBX needs physical hardware on site along with its upkeep, and extensions are tied to a particular desk. An IP PBX runs in software, so extensions work from a laptop or phone and capacity is far easier to expand.
Yes. Extensions work through a softphone on a laptop or mobile, so the team keeps taking and making calls under the office identity even while working elsewhere.
There is no physical PBX box to buy. Your team simply uses a softphone on the devices they already have, and a stable internet connection is the main requirement.
Routing is set by call purpose, operating hours, and extension availability. If one extension is busy, the call can be redirected automatically under the rules you define.
When a call arrives, the matching customer record opens on the agent's screen. The call history and notes are then saved automatically to the customer card in Barantum CRM.
Yes. You can try Barantum for free with no credit card, or schedule a demo with our team to see the IP PBX flow against your business needs.
