FAQ

Is Smart-SIP-Phone suitable for personal use?

Smart-SIP-Phone is designed for SIP telephone systems like Asterisk or Freeswitch. While it works for individuals, its features like white-label branding and CRM integration are primarily built for business and reseller environments.

Does the free version support background calls?

Yes, but it is limited to 50 call pushes per month. Once this limit is reached, you will not receive incoming calls while the app is in the background or locked.

What is the difference between this and a standard PBX softphone?

Smart-SIP-Phone is a universal client, meaning it is designed to work with many different SIP systems rather than being locked to one proprietary provider.

Are there free alternatives to Smart-SIP-Phone?

Many PBX providers offer their own proprietary softphone apps. If you are using a specific system, check if your provider offers a free, integrated client first.
