Top 10 Best Virtual Phone System Software of 2026

CallHippo combines a PBX-style call routing layer with DID number workflows so teams can connect business numbers to hunt groups and ring strategies. Inbound handling can be configured with IVR or menu flows and call queuing so callers reach the right queue instead of hearing a blank line. Outbound calling includes softphone and calling controls for agents in teams, with call logs feeding visibility during shift work.

A tradeoff is that deep CPaaS-style development and low-level call control are narrower than what Twilio or Plivo-like APIs target. CallHippo fits teams that need fast PBX configuration, consistent routing behavior, and CRM-friendly click-to-call workflows without running custom SIP plumbing.

Phone.com delivers hosted PBX capabilities with configurable call routing, including hunt-style behaviors for grouped users and conditional handling by call context. The WebRTC client reduces device friction by supporting browser-based calling without a dedicated desk phone. Admin workflows cover adding extensions, mapping inbound numbers to routing rules, and managing user access across teams. The automation surface is strongest when call events need to drive CRM actions, ticket creation, or outbound follow-up processes.

A key tradeoff is that deeper workflow automation depends on integrating Phone.com call events with external systems through APIs or webhook handlers. Phone.com fits situations where teams want telephony changes handled centrally and where developers already operate an integration service that can react to call metadata. It is less ideal when internal stakeholders expect drag-and-drop IVR editing or non-developer control over every call-flow branch.

Vonage Voice supports PSTN connectivity and number management workflows so organizations can assign and change DIDs as part of standard operations. Call routing and menu-driven call handling cover common PBX-style patterns like interactive menus and automated greetings, which reduces reliance on separate telephony boxes. The standout integration path is the Voice API paired with webhook delivery for events such as call progress and status changes. This combination supports both agent-facing phone behavior and back-office automation that reacts to telephony state.

A tradeoff appears in governance depth when compared with console-first PBX products that limit configuration surfaces, since API-led routing often requires stricter change control and documented call flow versions. Vonage fits teams that already build workflow automation and want call events to trigger CRM updates, ticket creation, or transfer decisions in near real time.

Dialpad combines cloud voice with team workflows like call transcription, summaries, and coaching inside the same admin environment. It supports office phone use through a browser-based calling experience plus managed endpoints, with routing controls for ring groups and hunt group style call distribution.

Admin tooling centers on number management, user provisioning, and permissions that apply across softphone and desk phone experiences. Automation and integration are strongest where Dialpad actions can be triggered by events and synced with CRM and support systems.

Twilio provides programmable voice calling APIs that drive virtual phone behavior for teams building custom call flows. It supports inbound and outbound calling, call routing via rules, and real-time events delivered through webhooks.

Twilio also offers built-in call recording controls and dialing capabilities that integrate with external systems through API and workflow automation. Governance is handled through account configuration and access controls tied to API usage, which supports audit-friendly operations for telephony workloads.

Krisp pairs AI call-noise removal with a virtual phone experience built around WebRTC voice and agent workflows. Teams can route calls to WebRTC client users and manage presence-like states for phone handling without building their own media stack.

Krisp also provides admin controls for team access, plus automation hooks that fit contact-center style routing and escalation patterns. The result is a voice setup where call quality improvements happen at the edge while call handling behavior stays centralized.

Hushed is a virtual phone system built around burner-number use cases and self-serve number management. It supports a WebRTC client so calls work from browsers without installing a full PBX.

Admin configuration centers on adding numbers, managing call forwarding, and controlling availability per line. Compared with API-first CPaaS voice offerings, Hushed focuses more on end-user dialing workflows than on deep call-routing automation.

Google Voice centralizes business calling with a web interface, phone-number management, and a desktop mobile experience. Call handling includes custom call routing, voicemail transcription, and message forwarding for multiple user endpoints.

The admin console supports user provisioning and group-based extensions for routing, while audit visibility is limited compared with dedicated PBX and CPaaS stacks. Google Voice is a browser-first voice workspace rather than a programmable telephony gateway for SIP interoperability.

Sideline provides a virtual phone system that pairs inbound call routing with team extensions and multi-location handling. The admin console supports call flows with time-based routing and hunt group behavior, plus role-based access controls for day-to-day management.

Extensions can be provisioned for desk phones, browser softphone use, or mobile clients, with call recording options tied to specific numbers and workflows. A Webhook-based integration layer lets external apps react to call events for workflows like CRM logging and ticket creation.

Microsoft Teams Phone is a virtual phone system built for organizations standardizing on Microsoft Teams for voice, meetings, and collaboration workflows. It provides calling numbers, call routing via Teams admin controls, and telephony policies that attach to user identities in Microsoft Entra ID.

Core call features include auto-attendant, call queues, and hunt group style ring behavior managed from the Teams admin center. Teams Phone also aligns voice administration with Microsoft 365 governance signals like RBAC-controlled administration and audit logs.
