Zoiper is a FREE IAX and SIP softphone application for voip calls over 3G or WiFi. There are NO ADVERTISEMENTS.
Zoiper softphone offers a simple user interface and superb audio quality for smooth Voice over IP experience.

WARNING: Please use only versions from the appstore, we have reasons to believe some of the (russian) .apk files floating on the web contain a trojan that might steal username and password and make fraudulent calls. The official zoiper from google play is safe to use. If you want all features without paying, don't pirate it but ask your friends for the unlocking cheatcode instead. First rule about the gold club: don't publicly publish the cheatcode, but share it privately at will.

Want to distribute it to your users ? Use the free automatic provisioning system on http://oem.zoiper.com and avoid tedious manual configurations!.

IMPORTANT: Zoiper softphone is a standalone client-side software VOIP phone application and is not bundled together with a voip service. To make and receive voip calls using Zoiper, you must subscribe to any SIP or IAX based service provider across the globe.

- Phones that are unstable because they have broken audio implementations:
Alcatel one touch series (poor audio drivers cause system freezes and crashes)
HTC one m8 (causes freezes.)

We tried to contact both alcatel and HTC to help them fix the issue, they didn't bother to reply. If you can help, let us know.

Warning: using Zoiper as a default dialer may interfere with dialing 911 emergency services.

If zoiper does not work with your phone, please contact us at support@zoiper.com and we will try to support your phone in future versions.

Vimphone by Vimtura Innovations is based on Linphone for Android by Belledonne Communications.

Vimphone is an open source Voice Over IP (VOIP) / SIP client for Android. The source can be downloaded at: https://bitbucket.org/vimtura/vimphone-android/ and contribution is welcomed. The Linphone for Android project was forked in March 2013, and so it is based on version 2.0. Which, as of this time is all of the current Linphone for Android features. Credit for the logo goes to arrioch for doing his "Blawb" icon theme from which it came (http://arrioch.deviantart.com/art/Blawb-208106783).

The reason for the fork was out of all the SIP clients for Android, Linphone for Android seemed the best. However, it still included some bugs and features that we didn't like. The core features of Linphone for Android are:

- Sleek interface with support for multiple accounts.
- Support for the following audio codecs: speex, G711, ILBC, GSM, SILK, G722.
- Support for the following video codecs: VP8, H264 and mpeg4.

The improvements / enhancements made in Vimphone are (not a complete list):

- Improvements to the call answering UI, with support for specialised SIP headers (currently to display Asterisk queue details - yet to be documented).
- Fixed the in-call transfer / multi-call features.
- Added feature to pause/hold before transfer or adding another party.
- Added feature to mute DTMF when dialling number to transfer / add.
- Fixed a bug to enable switching between WIFI / 3G seamlessly (using the "re-invite" SIP feature).
- Re-skinning as "Vimphone"
- Enhanced the setup assistant.
- Added feature to disable screen auto-rotation (useful if you are laying down).
- Fixed "notifications" (integration into Android for status icons and so on). This includes utilization of the phones "lights" (LEDS) for status display. In the previous version the icon always appeared the same regardless of status (at least on my version of Android).
- Added feature to allow "exiting".
- Fixed bugs with call history display (it was almost impossible to click on the "details" icon as the target area was tiny).
- Added call interception so the standard android dialler can be used and calls can be routed via Vimphone automatically (based on various conditions).
- Probably lots more? I'll document more as I remember :)
- Feel free to bug me for feature requests, or join in if you want to help!

This project / application is free and will always be free. It may not work the best on tablets as I do not own one, if you want tablet support please consider donating one to me.

Zadarma application for Android is very simple, easy to use and possesses next functions:
