Squaretalk Softphone review
A capable free Windows SIP client with useful CRM connections, but no macOS or mobile softphone.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Squaretalk Softphone is a free Windows desktop application for making and receiving VoIP calls through SIP accounts. It is aimed at business users who need standard desk-phone functions without a software license fee, including voicemail, call holding, and call forwarding. Open SIP support allows use with compatible SIP providers, carriers, and call-center systems. The product is a particularly direct fit for Windows-based teams that also work in Zoho CRM, Salesforce, Freshworks, or Pipedrive.
Its feature set covers core business calling and several technical controls. The softphone supports WebRTC echo cancellation, voice activity detection, background-noise suppression, and adaptive network handling. Codec compatibility includes Opus, G.711, G.722, and G.729. TLS and SRTP encryption can be configured, while multilingual and right-to-left localization and NVDA screen-reader compatibility address accessibility and language needs. These capabilities make it more suitable for varied business environments than a basic SIP dialer, although its scope remains centered on desktop calling rather than a broad contact-center suite.
The main trade-off is platform coverage: Windows is the listed platform, so organizations standardizing on macOS or mobile softphones should look elsewhere. Squaretalk separately lists paid contact-center platform plans, while the Softphone itself is presented as free; buyers seeking multiple Softphone tiers or packaged upgrades will not find that structure here. Choose Squaretalk Softphone for free SIP calling on Windows with CRM integrations and configurable voice features. Choose an alternative when cross-platform softphone access or a wider contact-center product is the primary requirement.
