Additional Features

Other notable features include call waiting, mute, hold, customizable ringtones per account, DTMF support, and more. Developers can access ZoiPer's VoIP SDK for building custom solutions or white-label versions, perfect for tailored business needs.

Important: ZoiPer is a standalone client-side application and does not include a VoIP service. Users must subscribe to third-party SIP or IAX providers to make calls.

While ZoiPer Pro offers robust features, users should be aware of a few considerations:

• Using ZoiPer as a default dialer may interfere with emergency calls like 911.
• It is recommended to download only from official sources to avoid security risks associated with unofficial APKs.
• Compatibility issues may arise on devices with poor audio drivers, such as certain Alcatel or HTC models, which might cause system instability.

Overall, ZoiPer Pro stands out as a versatile, high-quality SIP softphone solution that caters to a broad spectrum of users—from individual professionals to large organizations. Its support for multiple protocols, customizable interface, and strong security make it an ideal choice for those seeking reliable VoIP communication on mobile devices.
