7 Best Softphone Apps to Cut Call Costs & Boost Efficiency in 2025

As one of the top VoIP phone systems, RingCentral emerges as the best softphone app, with its all-in-one communication solution that combines VoIP calling, team chat, and video conferencing. Its robust call management system includes answering rules, call forwarding, call transfer, call screening, presence, call park, intercom, and paging.

Beyond its advanced call handling features, RingCentral integrates hundreds of third-party business tools, allowing users to enhance data accessibility across apps. Remote teams benefit from RingCentral’s artificial intelligence (AI)-powered collaboration tools, specifically for summarizing meeting topics, drafting quick messages, and transcribing conversations in real time.

RingCentral’s steep price point can be a major letdown for those looking to reduce their telecom spending. If you’re looking for a feature-rich softphone app that doesn’t break the bank, I recommend eVoice, which offers standard VoIP features for strengthening your professional phone presence.

• Advanced: Real-time analytics, customer relationship management (CRM) integration, efax, and call monitoring
• Core: Unlimited local calling, SMS/MMS, call menu, shared voicemail, AI-powered video meetings, call recording, team chat, phone administration, and call management
• Ultra: Unlimited storage and device analytics
• Free trial: 14 days

• Ring in order: Rearrange the order in which your numbers or devices ring at specific times, whether at once or sequentially.
• Corporate directory: Search individual contacts or groups within your company by their first and last name and hide specific contacts within the app.
• Push notifications: Select which notifications you want to receive for every incoming call, video call, and message.

Nextiva comes in second as the best VoIP softphone for sales and support teams engaging with clients across digital channels. It functions more than the standard softphone by providing a customer experience solution for connecting with customers on the platforms they prefer, whether social media, review websites, video, email, or live chat.

Customer and team interactions live together within one place, allowing for quick retrieval of information for faster response times and seamless collaboration. If you’re managing multiple teams, Nextiva’s remote management lets you edit user permissions and call flows and keep everyone’s workflow in sync regardless of location.

While Nextiva excels in digital channel support, it is lacking in terms of providing all-inclusive access to business phone features. Usage charges or monthly fees apply to core features like call recording, skill-based routing, analytics, and transcription. If you’re looking for a softphone app that provides the same phone features across plans, Ooma offers all the key calling features you need without plan upgrades.

• Digital: Website chat, messaging apps, email, two social media management accounts, helpdesk, unified inbox, and review management
• Core: Inbound/outbound voice, 100 SMS credits, customer video and screen sharing, call routing, voicemail transcription, and team chat
• Engage: Chatbot, 250 SMS, 10 social media management accounts, e-fax, 2,000 toll-free minutes, call center capabilities, call recording, and voice analytics
• Power Suite: 10,000 toll-free minutes, unlimited SMS credits, and unlimited social media management accounts

• Unified inbox: Consolidates all conversations (calls, texts, video, SMS, social, and chatbots) into one place and displays client interactions within a single thread.
• Contact management: This built-in contact management tool seamlessly imports Google and Office 365 contacts and lets you manually add contacts with their numbers, emails, and notes.
• Message Pro: When a client texts your company number, a team member or multiple users can respond and manage the interaction without the need for handoffs.

Among VoIP softphone providers, Ooma is widely known as a residential phone system for solopreneurs and startups managing their businesses from home. A one-time purchase of its Ooma Telo adapter includes a free residential phone plan with unlimited nationwide calling.

While primarily a home phone service, the Ooma Office softphone boasts high ratings for its desktop and mobile apps on both Android and iOS app stores. Ooma earned 4.9 out of 5 stars among iOS users, particularly its rich functionality, consistent reliability, and ease of use.

Ooma, however, falls short in remote collaboration, lacking the advanced video meeting and chat room capabilities offered by industry leaders like RingCentral, which leverages AI for more efficient interactions and workflows.

• Home plans
  • Basic: Unlimited nationwide calling, voicemail, call waiting, and call logs
  • Premier: Enhanced caller ID, advanced call blocking, and call forwarding to the Ooma app
• Office plans
  • Essentials: One toll-free number, 50-plus phone features, ring groups, call blocking, and virtual receptionist
  • Pro: $24.95 for SMS/MMS, hybrid ring groups, call recording, call analytics, voicemail transcription, and 25-attendee video meetings for four hours
  • Pro Plus: $29.95 for call queues, call screening, 100-attendee video meetings for 12 hours, hot desking, and CRM integrations

• Hot desking: Temporarily log into any desk phone in your office and use your active phone line, voicemail, and caller ID when making an inbound or outbound call.
• Shared speed dial: Provide company-wide access to a custom phone book that stores all employee names and extensions for seamless call routing.
• Dynamic caller ID: Instantly change your caller ID for outbound calls by simply dialing the assigned number code for your preferred caller ID, followed by the number you wish to dial.

Grasshopper is an ideal platform for first-timers, thanks to its no-frills softphone app built only for voice calling and texting. Unlike other providers, it only has the standard VoIP features, making it easy to use and navigate. Its features include VoIP calling, call forwarding, call transfer, custom greetings, voicemail transcription, and incoming call control.

I also recommend Grasshopper for budget-conscious teams as it uses flat-rate pricing, unlike most providers that follow a per-user pricing model. This means adding an unlimited number of users to your account without necessarily increasing your monthly cost—benefitting startups and small teams trying softphone services for the first time.

Before subscribing to Grasshopper, note that additional numbers cost $10 monthly. If this is going to be a budget concern, choose eVoice, which includes an extra three numbers per plan.

• True Solo: One user, one phone number, one extension, call forwarding, incoming call control, call transfer, voicemail, virtual fax, and business texting.
• Solo Plus: Unlimited users, one phone number, call recording, call transfer, simultaneous call handling, and three extensions 
• Small Business: Four phone numbers and unlimited extensions 
• Free trial: 7 days

• VoIP + WiFi calling: Use the internet for voice calling and text messaging if you wish to save on data and minutes or if you have poor cellular reception.
• Virtual fax: Have your incoming faxes delivered to your email in PDF format.
• Toll-free vanity numbers: Upon sign-up, Grasshopper lets you select a toll-free vanity number for your business line at no extra charge.

Acrobits Softphone is the best softphone app for teams seeking flexibility in setting up multiple SIP accounts in one softphone app. Whether you’re using Acrobit’s basic VoIP client or white-labeled app, users have the freedom to add and configure SIP lines from different VoIP providers.

Each SIP account will have its own settings, call rules, caller ID, and ring sound. When sending or receiving calls, you can toggle between service providers without leaving the app. This is ideal for call center environments where agents need to manage multiple phone numbers from different VoIP providers — allowing them to handle all communications within a single app with greater efficiency and organization.

To manage high call volumes, users may want to consider feature-rich alternatives, as Acrobits may not support all the phone features needed for handling call flows. Instead, I strongly recommend Ooma, which offers all the core VoIP features you need, whether for handling call traffic, blocking spam numbers, and forwarding calls.

• Acrobits Softphone: A basic softphone app designed for individual users and small businesses. It includes unlimited access to SIP accounts, standard customization features, lifetime support, and feature updates.
• Acrobits Groundwire: This is a more advanced version of Acrobits Softphone built for enterprise settings with features such as attended/unattended transfers, voicemail, group calls, and presence.
• Full-featured: Supports incoming and outgoing calls, including access to push notifications, call transfers, video calls, and conferencing.
• Outgoing only: For a flat monthly fee, this softphone app lets you make unlimited outgoing calls.
• Enterprise: This works for businesses with a large user base and requires complete unified communications capabilities (with self-hosted or Acrobits-hosted options).
• White label: Deploy your branded VoIP app with robust customizations and advanced features for voice calls and video chats.

• Call flows: Supports attended and unattended transfers, allowing businesses to direct calls either to a human operator or auto-attendant/IVR.
• Unified login: Eliminates manual entry of usernames and passwords by allowing users to choose from multiple authentication methods such as QR codes, single sign-on, and biometrics.
• Push notifications: Send alerts to your clients amid poor reception and activate alerts only when necessary to prevent their battery from draining.

Aside from Acrobits, Zoiper is one of the most frequently talked about in online forums, specifically among businesses seeking a customizable softphone to incorporate their brand. A white-label softphone like Zoiper lets you add branding elements such as your company’s logo, color swatches, fonts, icons, and feature set without developing a softphone app from scratch.

Users with basic softphone needs can opt for the free version of Zoiper 5, which is limited to voice calls. A one-time upgrade to Zoiper 5 Pro unlocks lifetime access to SIP calling, telephony features, contact management, security features, video calling, and instant messaging.

While Zoiper is widely used, some users point out a few network issues and its outdated interface. Tech-savvy teams seeking to enhance customer service with a modern, user-friendly app may find Nextiva a strong alternative.

• Zoiper 5: Make two simultaneous SIP calls with echo cancellation features
• Zoiper 5 PRO: Upgrading to the business edition gives you lifetime access to Zoiper’s SIP softphone app and all the standard features for voice calls, video conferencing, and contact management.

• Ignore call function: Turning on this feature prevents you from receiving another incoming call if you are in an active conversation.
• Auto-answer: Automatically accept an incoming call without manually picking up the phone or tapping a button.
• Command-line dialing: Initiate voice calls through a command terminal instead of the usual softphone interface, perfect for automations and CRM integrations.

eVoice offers a cost-effective solution for solopreneurs looking to build their credibility for their small businesses. Beyond handling phone calls, it offers an array of professional services such as virtual phone numbers, live receptionist, and professional phone greetings. This lets you easily establish multiple phone lines, have a trained operator to field customer inquiries, and create a memorable impression for your callers — all for a minimal monthly fee.

Despite being last on our list, eVoice doesn’t disappoint in terms of delivering value. Its single pricing model offers all the features you need for handling inbound calls such as voicemail, call routing, auto-attendant, and merged calling.

Like Grasshopper, eVoice misses the mark when it comes to supporting additional channels like video calls and instant messaging. For a more comprehensive alternative, RingCentral offers an all-in-one softphone with integrated VoIP calling, team messaging, and video meetings.

eVoice uses a single plan structure that includes three phone numbers and core phone features such as voicemail, multiple extensions, call routing, blocking, and virtual fax. Additional fees apply for call recording, unlimited SMS, voicemail transcription, live answering, and professional recording.

• Live receptionist: Hire a team of professionally trained phone receptionists to handle incoming calls, admin tasks, and appointment bookings.
• Professional greeting: Have your welcome message and voicemail greeting recorded by an experienced voice talent to establish a good first impression to your callers.
• Merged calling: Host a conference call with up to 94 participants.
