Top 10 VoIP Solution Providers for Local Offices

1. Mole Networks (Local SIP Trunking)

Mole Networks is a Kuala Lumpur–based operator with its own MCMC apps service provider (ASP) licence and direct interconnect to TM, Maxis, and CelcomDigi PSTN. They deliver DID numbers in the 03-xxxxxxx block, per-channel SIP trunks, and fax-over-IP, and they are the default trunk provider for many Malaysian 3CX and Grandstream installations. Their SBC supports G.711a and G.729, with an advertised blocking probability under 0.01% during peak weekday hours. Most Klang Valley offices terminate 10 to 50 concurrent channels starting at RM 18 per channel per month, plus a one-time DID setup of RM 50 per number.

2. 3CX (Self-Hosted PBX)

3CX is the standard software PBX for local offices that want their telephony inside their own firewall. The Linux installer runs on a standard Dell or HPE tower; you set up SIP trunks from Mole or any carrier that publishes a working gateway config. Malaysian integrators commonly deploy the free Standard edition (8 simultaneous calls) or the Pro licence at roughly RM 1,200 per year for 16 SC. It gives you WebRTC calls directly in the browser, auto-provisioning for Yealink and Snom handsets, and a native Windows/macOS softphone that works fine on a 10 Mbps office line—one G.711 call runs at 87 kbps, so bandwidth is rarely the bottleneck.

3. Yeastar (Hybrid On-prem/Cloud)

Yeastar’s S-Series and P-Series are common in Malaysian SME offices because they act as a gateway, PBX, and SBC in one physical box. The S100 can handle 150 registered extensions and 40 concurrent calls, while the P-Series adds failover to a 4G USB dongle—useful in Bangsar or Shah Alam buildings where fibre cuts happen. Linkus softphone integrates with Outlook and local mobile numbers. Typical reseller pricing in KL for an S100 with 8 SIP trunk channels is RM 2,800 to RM 3,500, excluding installation, and it supports both analogue FXS ports for legacy fax machines and full PRI/E1 cards if you are migrating off a TM PRIMA line.

4. Cisco Webex Calling

Cisco Webex Calling is a true cloud PBX being sold by Malaysian Cisco partners like SoftwareONE and Microsource. It scales from 10 users to multi-site, and you can keep local DIDs from the 03 range by porting numbers from your existing carrier into the Webex Calling PSTN service. The Control Hub admin console gives you per-site dial plans, call park, hunt groups, and automated call recording for compliance—useful for property management firms in KL. Pricing is roughly USD 10 to USD 15 per user per month at the Standard level, billed in USD, so a 30-person office ends up around RM 1,300 a month inclusive of local DID rental.

5. RingCentral MVP (Cloud PBX)

RingCentral MVP is sold through regional resellers in Malaysia and is a workable option for offices that need unified comms—voice, SMS, and fax—without owning any hardware. The Advanced tier includes unlimited calling within Malaysia when you buy the Global Office plan, which routes DIDs through local interconnect; a 03-xxxxxxx number from the reseller pool is delivered in about two working days. It handles deployment-heavy tasks cleanly: you can set an auto-receptionist with branch-specific menus for a KL HQ and a Johor Bahru branch, and the admin portal logs all voice hours per extension. Expect RM 110 to RM 140 per user per month at the mid-tier, which is higher than a 3CX setup but zero-maintenance.

6. Maxis Business SIP Trunking

Maxis offers carrier-grade SIP trunking as an add-on to its Business Fiber plan. You get a fixed number of concurrent channels—usually 5, 10, or 20—backed by Maxis’ SLA, and calls are terminated on their own MPLS/IP backbone without hairpinning through a third-party gateway. For a branch office that also runs cloud POS or CCTV, this keeps QoS on the same pipe. A standard quote for 10 channels and 10 DID numbers is around RM 350 per month with a 24-month contract, including installation of a Cisco or Adtran IAD at your premises. It works cleanly with 3CX and Yeastar if you configure the recommended Maxis gateway template from their support portal.

7. TIME Business Voice

TIME’s SIP trunking and PRI services run exclusively on its own fibre backbone, which covers Bandar Utama, Mont Kiara, PJ, Cyberjaya, and key enterprise corridors. That matters for latency: TIME advertises under 30 ms jitter on their last mile, which translates to clear G.711 calls without echo. They offer both per-channel metered and flat-rate unlimited local call bundles. A 10-channel flat-rate trunk with 10 DIDs lands near RM 400 per month, and TIME’s network operations centre is based in KL—so fault tickets are handled locally rather than through a US or India escalation chain, a real operational advantage over global UC vendors.

8. CelcomDigi Business Telephony

Since the CelcomDigi merger, the business unit has been quietly servicing SIP trunking and cloud PBX accounts for retail and branch-heavy industries. Their strength is nationwide PSTN presence: they can assign DID numbers with the correct geographic prefixes for Penang (04), Ipoh (05), Melaka (06), Johor (07), and other states, without forcing porting through a third-party long-distance carrier. If your “local office” is actually a cluster of branches in Seremban and Kuantan, CelcomDigi gives you per-branch DIDs on one consolidated monthly bill. Volume pricing is more negotiable than Maxis or TIME—enterprise sales circulate public rate cards starting at RM 25 per channel.

9. Twilio Elastic SIP Trunking

Twilio’s Elastic SIP Trunking is not a PBX; it is for companies with in-house Linux engineers who want to terminate voice traffic into their own Asterisk or Kamailio stack. It gives you programmable control over routing, CDR data, and failover to mobile numbers—all via Twilio’s REST API. For a Malaysian office that already builds its own middleware, Elastic SIP trunks cost about USD 0.05 per inbound minute and USD 0.02 per outbound minute to Malaysian mobiles. Local Malaysian DIDs are issued through Twilio’s regional partner network; you cannot get a true 03 number directly from Twilio, so you will need to configure the DID at your carrier and point it to your Twilio trunk with SIP forwarding.

10. CWW (Commenius Worldwide)

CWW Group is a Malaysian-established telecom operator with roots in business voice and best known for aggressive SIP trunk pricing. They hold MCMC licences and terminate calls directly with TM, Maxis, and the smaller Malaysian carriers, which keeps per-minute rates low—often RM 0.015 to RM 0.025 per minute to Malaysian mobile numbers. Small offices who are price-sensitive will find their per-DID fee around RM 10 monthly and per-channel fees as low as RM 15. CWW also sells integrated hosted PBX packages with a web portal for call recording and extension management, and their engineering team is physically present in PJ for on-site maintenance of SBC units—rare for a trunk-only provider.
