Zoiper softphone is a user-friendly application that allows for high-quality Voice over IP (VoIP) communication. It can be used for both SIP and IAX systems and is suitable for end users, service providers, call centers, and businesses looking to utilize VoIP technology. The application can also be customized with a company's logo and branding or integrated into their own solution using Zoiper's VoIP SDK.
For those interested in distributing Zoiper to their users, there is a free automatic provisioning system available to avoid manual configurations. However, it is important to note that Zoiper is a standalone client-side software and does not come bundled with a VoIP service. Users must subscribe to a SIP or IAX based service provider in order to make and receive calls using Zoiper.
Zoiper offers a variety of features including support for different color schemes, Bluetooth connectivity, and low battery usage. It also has excellent audio quality, even on older devices, and supports calling over 3G and WIFI. The application is multiprotocol with SIP and IAX support, making it compatible with all RFC compliant PBXs. It also has background and multitasking support, integration with the native android contact list, and the ability to mute and hold calls.
Other features of Zoiper include support for various codecs, sending DTMF, DNS SRV, built-in echo cancellation, and STUN support. It also allows for changing ringtones per account, call waiting, and video support with a subscription. For added security, Zoiper offers ZRTP/TLS support and call transfer with a subscription. It also has wideband audio capabilities.
Zoiper is available as a customized branding solution or VoIP SDK for those interested. However, it is important to note that there have been reports of unstable performance on certain devices, such as Alcatel one touch series and HTC one m8. Additionally, using Zoiper as a default dialer may interfere with dialing emergency services. It is recommended to only download Zoiper from the official Google Play Store to avoid potential security risks.
