What Are the 7 Best VoIP Providers in Singapore for 2026?
1. FreJun
FreJun is the top-rated VoIP provider for Singapore sales and support teams, combining AI-powered call automation with deep CRM integrations. Unlike traditional telecom providers, FreJun operates entirely in the cloud — meaning your team can make and receive calls from any browser or mobile device without hardware. FreJun provides Singapore virtual numbers, SIP trunking, hosted PBX, and a full suite of Unified Communications (UC) services that integrate voice, video, and messaging into one platform.
Furthermore, FreJun’s AI insights automatically transcribe calls, surface coaching opportunities, and log every interaction to your CRM — eliminating manual data entry. As a result, sales teams using FreJun report faster follow-up cycles and higher call-to-meeting conversion rates. FreJun’s autodialer and click-to-call features further reduce idle time between outbound calls, making it the strongest choice for high-volume outbound teams in Singapore.
Key Features: Calling, autodialer, click-to-call, voice broadcast, AI insights, call routing, virtual number, call transcript, CRM/ATS integration, reports and analytics, and Chrome extension.
Pricing: Basic plan starts at $19/user/month.
G2 Rating: 4.9 out of 5
2. StarHub
StarHub is one of Singapore’s largest telecommunications companies, offering enterprise-grade VoIP through its SmartUC platform. StarHub’s Business Voice solutions include SIP Trunking (Session Initiation Protocol trunking, which replaces traditional phone lines with internet-based connections), Hosted PBX, and unified communications. The SmartUC platform incorporates instant messaging, voice, and video conferencing into a single interface, making it a strong fit for larger organizations that need a carrier-grade solution with local support.
However, StarHub’s pricing is less transparent than FreJun’s, and its AI-powered features are more limited. That said, StarHub’s network reliability and dedicated enterprise support make it a credible option for companies that prioritize telecom-grade uptime over advanced automation.
Key Features: Caller ID, call waiting, call transfer, call forwarding, sequential call, simultaneous ring, and voicemail-to-email.
Pricing: Basic plan starts at $20.19 per user per month.
G2 Rating: Not rated
3. M1
M1 is one of Singapore’s leading telecommunications companies, providing SIP Trunking, Hosted PBX, and Cloud Voice services for businesses of all sizes. M1’s Cloud Voice platform includes auto-attendant, call forwarding, and call recording — making it a practical choice for enterprises that want a managed VoIP solution backed by a licensed Singapore telecom operator. Additionally, M1’s customer-centric onboarding process simplifies the transition from traditional PSTN lines to cloud telephony.
In contrast to FreJun, M1 does not publish transparent pricing online, which can slow down procurement decisions for fast-moving teams. Similarly, M1 lacks native CRM integrations, meaning sales teams would need third-party middleware to connect call data to their pipeline tools.
Key Features: Call barring, call waiting, call divert, caller number display, and three-party voice conference.
Pricing: Contact the M1 team for pricing details.
G2 Rating: Not rated
4. MyRepublic
MyRepublic is a Singapore internet service provider that extends its high-speed broadband infrastructure into cloud VoIP services for businesses. Their Cloud Voice platform delivers call forwarding, voicemail, call transfer, call waiting, conference room calls, music on hold, call recording, and ACD (Automatic Call Distribution) — a feature that routes incoming calls to the most appropriate agent based on predefined rules. MyRepublic’s bundled broadband-plus-VoIP approach can reduce total communication costs for SMEs already using their internet services.
For example, a 20-person SME using MyRepublic’s broadband can add Cloud PBX without switching providers, simplifying billing and support. However, MyRepublic’s VoIP feature set is less advanced than FreJun’s, with no native AI transcription or CRM integration.
Key Features: Conference room calls, music on hold, call recording, call waiting, voicemail, Automatic Call Distribution (ACD), and unlimited internal extensions.
Pricing: Contact the MyRepublic team for pricing details.
G2 Rating: Not rated
5. Velox Networks
Velox Networks is a Singapore-based IT solutions provider that bundles VoIP phone systems within broader managed IT service packages. Their platform targets businesses that want a single vendor to handle both their network infrastructure and business telephony. Velox delivers video conferencing, call recording, and auto-attendant as core features, making it suitable for professional services firms and mid-sized companies that prefer an IT-managed deployment model.
That said, Velox’s VoIP offering is narrower in scope than FreJun’s. Specifically, it lacks native CRM integrations, AI call analytics, and autodial capabilities — features that matter most to outbound sales teams. Instead, Velox excels when VoIP is one component of a larger IT infrastructure project.
Key Features: Video conferencing, call recording, and auto-attendant.
Pricing: Contact the Velox sales team for pricing details.
G2 Rating: Not rated
6. SIPTEL
SIPTEL specializes in affordable, feature-rich VoIP solutions for Singapore SMEs, offering Cloud PBX, SIP Trunking, and DID (Direct Inward Dialing) number services. DID numbers give each employee a unique local Singapore number without requiring a separate physical line, which reduces hardware costs significantly. SIPTEL focuses on seamless migration from traditional telephony to IP-based communication, making it a practical entry point for businesses moving away from legacy phone systems for the first time.
Moreover, SIPTEL’s call routing, simultaneous ring, and caller ID features cover the essential needs of most SMEs. However, businesses that need advanced analytics, AI transcription, or CRM integration will find SIPTEL’s feature set limited compared to FreJun.
Key Features: Call logs, call hold, call routing, simultaneous ring, call transfer, caller ID, and do not disturb.
Pricing: Contact the SIPTEL sales team for pricing details.
G2 Rating: Not rated
7. CallHippo
CallHippo is a cloud-based VoIP provider that gives Singapore businesses a virtual local presence without physical hardware. Their power dialer, global connect, smart switch, call barging, call conference, IVR (Interactive Voice Response), and automated call distribution features make CallHippo a strong option for outbound sales teams targeting multiple international markets simultaneously. Additionally, CallHippo’s intuitive interface reduces onboarding time for new sales reps.
In contrast to FreJun, CallHippo’s AI features are less mature, and its G2 rating of 4.4 out of 5 reflects occasional call quality issues on certain international routes. For teams focused purely on global outbound volume at a low entry price, CallHippo remains a competitive alternative.
Key Features: Power dialer, global connect, smart switch, call barging, call conference, automated call distribution, and voicemail.
Pricing: Basic plan starts at $18 per user per month.
G2 Rating: 4.4 out of 5
How Does VoIP Change Business Communication in Singapore?
VoIP technology transforms how Singapore businesses communicate by replacing expensive PSTN infrastructure with internet-based calling. According to Grand View Research’s 2024 VoIP Services Market Report, the global VoIP market reached $40.2 billion in 2023 and projects a 9.1% CAGR through 2030 — driven largely by Asia-Pacific enterprise adoption. For Singapore businesses specifically, switching to VoIP reduces international call costs by 40-60% compared to traditional landlines (Source: IMDA 2024).
The table below shows the measurable impact VoIP delivers across key business factors:
| Business Factor | Before VoIP | After VoIP |
|---|---|---|
| Call Costs | High (PSTN rates) | 40-60% lower |
| Communication Speed | Moderate | Instant, HD Voice |
| Call Quality | Variable | HD Voice (G.722 codec) |
| Global Reach | Limited by line capacity | Unlimited virtual numbers |
| Scalability | Restricted by hardware | Add users in minutes |
| CRM Integration | Manual logging | Automatic sync |
What Security Measures Do These VoIP Platforms Offer?
VoIP platforms operating in Singapore must meet both technical security standards and local regulatory requirements. Singapore’s PDPA (Personal Data Protection Act) governs how call recordings and customer data are stored and processed. Additionally, enterprise VoIP platforms typically implement TLS (Transport Layer Security) and SRTP (Secure Real-time Transport Protocol) to encrypt call signaling and media streams respectively.
Key security measures across leading Singapore VoIP providers include:
- End-to-End Encryption: TLS and SRTP protocols protect call data from interception during transmission.
- Secure User Authentication: Multi-factor authentication (MFA) prevents unauthorized account access.
- Data Compliance: Adherence to PDPA and GDPR standards where applicable.
- Network Firewalls and Anti-DDoS Protection: Safeguards VoIP servers from cyber attacks targeting SIP infrastructure.
- Call Logging and Monitoring: Tracks call activity for security audits and fraud detection.
Quick Tip: When comparing providers, always verify their security certifications and confirm whether call recordings are stored in Singapore-based data centers to maintain PDPA compliance.
What Are the Common Challenges When Choosing a VoIP Provider?
Selecting the right VoIP provider involves navigating several practical challenges that many buyers overlook during evaluation:
- Variable Call Quality: Poor internet bandwidth leads to dropped or delayed calls. Providers should offer a minimum 100 kbps per concurrent call and support QoS (Quality of Service) prioritization.
- Hidden Costs: Extra charges for international calls, number porting, or advanced features can inflate the total cost of ownership beyond the advertised per-seat price.
- Limited Integrations: Some platforms do not sync natively with CRM tools like HubSpot, Zoho, or Salesforce — requiring costly middleware or manual data entry.
- Feature Overload: Advanced features like predictive dialers or IVR builders can overwhelm small teams without dedicated IT support.
- Customer Support Delays: Not all providers offer 24/7 assistance, which creates risk for teams operating across multiple time zones.
How Can Different Teams Benefit from VoIP Services?
VoIP platforms serve multiple departments across a Singapore business, each with distinct use cases:
- Sales Teams: Automate outbound calls with power dialers, track lead conversations, and sync call outcomes directly to CRM for better pipeline visibility.
- Support Teams: Record calls for quality assurance, use AI transcription to identify recurring issues, and route calls intelligently with IVR to reduce wait times.
- Remote Teams: Make and receive calls from any device using mobile or desktop apps, with real-time analytics available from any location.
- Recruitment Teams: Conduct virtual interviews, schedule calls through CRM or ATS integrations, and track candidate interactions efficiently.
- Education and Healthcare: Facilitate remote consultations, virtual classes, and telehealth services securely with encrypted call channels.
How Can Businesses Choose the Right VoIP Provider for Their Needs?
Choosing the best VoIP provider in Singapore requires a structured evaluation across six dimensions. First, assess your team size and call volume to match the right plan tier. Next, identify the specific features your workflows require — such as call recording, IVR, CRM integration, or AI transcription. Then compare pricing tiers carefully, including any charges for international calls or add-ons that are not included in the base plan.
Six-Step VoIP Provider Evaluation Framework
- Business Size and Usage: Match the plan with your team size and expected monthly call volume.
- Required Features: Identify essential tools — call recording, IVR, CRM integration, autodialer, and analytics.
- Budget: Compare pricing tiers and calculate total cost including international call rates and add-ons.
- Reliability and Call Quality: Check uptime SLAs (target 99.9%+), user reviews on G2 or Capterra, and network redundancy.
- Security and Compliance: Confirm end-to-end encryption (TLS/SRTP) and PDPA-compliant data storage.
- Support and Training: Prioritize providers offering 24/7 customer support, onboarding assistance, and a knowledge base.
In our experience deploying VoIP for hundreds of Singapore businesses, the most overlooked factor is CRM integration depth. Teams that choose a VoIP provider without native CRM sync spend an average of 45 minutes per day on manual call logging — time that compounds into significant productivity loss at scale. FreJun eliminates this entirely through one-click integrations with HubSpot, Zoho, Salesforce, Pipedrive, and Freshworks.

Frequently Asked Questions About VoIP Providers in Singapore
1. What should I look for in a VoIP provider in Singapore?
Prioritize HD call quality, CRM integration, local Singapore virtual numbers, and transparent pricing. FreJun delivers all of these with added AI transcription and call automation. Additionally, verify that the provider complies with Singapore’s PDPA for call recording storage. Look for a G2 or Capterra rating above 4.5 to confirm real-world reliability before committing to a plan.
2. Which VoIP service is best for small businesses in Singapore?
FreJun is the strongest choice for small businesses due to its affordable $19/month plans, browser-based access, and smart features that eliminate complex hardware setups. SIPTEL is a credible alternative for teams that need basic Cloud PBX and DID numbers at a lower entry cost. However, FreJun’s CRM integrations and AI features deliver significantly more value as your team scales beyond 10 users.
3. Can I use a VoIP system without hardware or installation?
Yes — FreJun works entirely in a browser with no downloads or hardware required. Your team can start making calls within minutes of signing up. Similarly, CallHippo and MyRepublic offer cloud-based access. However, some providers like M1 and StarHub may require IP phones or SIP adapters for certain plan tiers, so confirm hardware requirements before purchasing.
4. Which VoIP solution supports integration with tools like Zoho or HubSpot?
FreJun integrates natively with HubSpot, Zoho, Salesforce, Pipedrive, Freshworks, and Leadsquared — keeping all call data and contact records in sync automatically. CallHippo also offers CRM integrations, though with fewer native connectors. In contrast, StarHub, M1, and SIPTEL do not offer native CRM integrations, requiring third-party middleware for data sync.
5. Is there a VoIP solution in Singapore suitable for remote teams?
FreJun is purpose-built for remote and hybrid teams — it runs in any browser, supports mobile apps, and provides real-time call analytics from any location. Additionally, FreJun’s virtual Singapore numbers let remote employees present a local number to customers regardless of where they are physically located. This makes FreJun the top choice for distributed teams operating across Southeast Asia.
6. What is the best VoIP provider for outbound sales in Singapore?
FreJun leads for outbound sales with its power dialer, predictive dialing, click-to-call, and real-time analytics. These features reduce idle time between calls and give sales managers full visibility into rep performance. CallHippo is a secondary option for teams focused on global outbound volume. However, FreJun’s AI call transcription and CRM sync give it a decisive advantage for teams that need coaching insights alongside call volume.
7. Is call recording available in VoIP systems in Singapore?
Yes — FreJun automatically records and stores calls securely, with easy access for training, quality assurance, and PDPA compliance. M1, MyRepublic, and StarHub also offer call recording as part of their hosted PBX plans. Additionally, FreJun pairs call recordings with AI-generated transcripts and summaries, making it faster to review conversations and extract coaching insights without listening to full recordings.
8. Do VoIP services in Singapore offer free trials?
FreJun offers a 2-day free trial so teams can test calling, CRM integration, and AI features before purchasing. Most telecom-based providers like StarHub and M1 do not offer self-serve trials — instead, they require a sales consultation. For the fastest evaluation, FreJun’s trial gives you immediate access to all core features without a credit card.
9. What features should I look for in a VoIP provider?
The most important VoIP features for Singapore businesses are call routing, IVR, call recording, CRM integration, mobile apps, and real-time analytics. Additionally, AI transcription and autodialing are increasingly critical for sales teams. For support teams, ACD (Automatic Call Distribution) and voicemail-to-email are essential. Prioritize providers that offer all of these natively rather than through third-party add-ons that increase cost and complexity.
10. Can small businesses benefit from VoIP in Singapore?
Absolutely — VoIP scales to any business size, making it ideal for small, medium, and large teams. Small businesses benefit most from eliminating PSTN line rental costs, gaining virtual Singapore numbers, and accessing enterprise-grade features like call recording and CRM integration at a fraction of traditional telecom pricing. FreJun’s $19/month entry plan makes professional VoIP accessible from day one without long-term contracts.
