SIP Trunking

Connect your PBX to a resilient carrier backbone

Make and receive high-quality digital calls over the internet with secure, reliable SIP trunking. Keep your existing phone system and add concurrent channels as your call volume grows.

Understanding SIP Trunking

What is SIP trunking — and how it cuts your line costs

Plenty of Malaysian businesses already own a capable PBX — it works fine. What's expensive is what feeds it: rows of ISDN or analogue lines, rented per channel, billed every month whether you use them or not.

A SIP trunk replaces those physical lines with voice channels delivered over the internet. Your PBX stays exactly where it is; we simply connect it to a licensed carrier digitally — so you keep the system you know, drop the line rental, and add or remove channels on demand.

How SIP trunking works

STEP 01

Keep your existing PBX

Your on-site or hosted PBX stays in place — we connect to it over a SIP trunk instead of copper or ISDN lines.

STEP 02

Lines become flexible channels

Each concurrent call uses one channel; scale channels up for a campaign or down in quiet months without re-wiring anything.

STEP 03

Numbers and failover built in

Bring your existing numbers or add new DIDs, with automatic failover to mobile or another site if a link drops.

SIP trunking is usually the fastest telecom saving a business with an existing PBX can make — lower line rental, instant capacity for busy periods, and DID numbers across Malaysia — without throwing away equipment you've already paid for.

FAQ

SIP Trunking questions

A SIP trunk is a virtual replacement for traditional phone lines: instead of ISDN or analogue lines, your PBX connects to a licensed carrier over the internet. Each trunk carries multiple concurrent calls as channels, which you scale up or down on demand.

No — that is the whole point. SIP trunking keeps your existing on-site or hosted PBX and simply changes how it connects to the outside world, so you protect your investment while cutting line costs.

One channel carries one simultaneous call, so size it to your busiest moment — a rough guide is one channel per 3–4 staff who phone regularly. We review your call patterns and you can adjust channels as you grow.

Yes. We can port your existing numbers onto the trunk and provision new DID (direct-dial) numbers across Malaysian area codes, so departments or campaigns get their own lines.

Calls automatically fail over — to a backup link, to mobile numbers, or to another site — so customers still reach you. Failover rules are configured up front and run without manual intervention.

Most businesses see a clear drop in monthly line rental plus cheaper call rates, because you stop paying for fixed physical lines you do not always use. The exact saving depends on your current line count and call volume — we size it before you switch.

Scale your call capacity, not your costs.
