How IP phone systems work
VoIP, SIP and PBX — the key components explained
- VoIP (Voice over IP) — voice calls transmitted as data packets over your network rather than dedicated telephone lines. Lower per-call cost and easier extension management than traditional PBX.
- SIP protocol — the standard used by IP phones to connect to the PBX and route calls. SIP phones (desk handsets) plug into the network switch directly and register to the PBX by IP address.
- IP PBX — the central call manager. Handles extension dialling between internal phones, auto-attendant (press 1 for sales…), call queuing and transfer. Can be hardware-based or cloud-hosted.
- Hosted vs on-premise — cloud PBX is maintained by a provider; on-premise PBX hardware sits in your office. NEXT IN™ advises on the right model based on team size, budget and internet reliability.

Frequently asked questions
An IP phone system (also called VoIP or SIP phone system) routes voice calls over your office data network instead of traditional telephone lines. Each desk phone connects to the network switch and registers to a central PBX (call manager) that handles extensions, auto-attendant, call transfer and voicemail. NEXT IN™ supplies SIP desk phones and configures the PBX for offices across Klang Valley.
Yes. SIP-based IP phones can register to the same PBX from any location with a stable internet connection — including home offices or branch locations. Remote extensions appear as standard internal extensions, enabling internal dialling and shared call queues regardless of physical location.
A SIP trunk is the connection between your IP PBX and the public telephone network (PSTN), provided by a VoIP carrier. It replaces traditional telephone lines and carries inbound and outbound calls as data. The number of simultaneous calls determines the trunk capacity required. NEXT IN™ advises on SIP trunk sizing as part of the IP phone project scope.
IP phones share the office internet connection but benefit from QoS (Quality of Service) configuration that prioritises voice traffic over other data. A stable, low-latency connection (fibre broadband) is recommended. NEXT IN™ configures network QoS as part of IP phone setup to ensure call quality is not affected by general internet usage.
