With Zangi you can place a call to anyone in the world for free if they’re also a Zangi user. To make a call, you will need a Wi-Fi, 2G/ 3G/ 4G/5G connection. Making Zangi Voice Calls If you want to make an audio call, go to Calls → Open Keypad, then dial the Zangi number you want to call. Tap the call button, and choose from the available options: Call, Video, or Chat. You can also call someone directly from an open chat. Open the conversation with the contact you want to call, then tap the call icon in the upper-right corner of the chat screen. From there, choose Voice Call to start an audio call.

Zangi - Private Messenger uses leading-edge cryptography to protect calls between sender and receiver, as well as the communication between the app and the servers. Zangi encryption is always on for any type of communications through Zangi and there is NO option to remove or disable it.

When making a call you will see several statuses of the call: First it’ll say Calling, then quickly change to Ringing (request sent to person you’re trying to call), and then the timer will start once that person picks up the phone. If it says Answering, instead of Ringing, then there’s a calling error. Please try again.

To change your ringtone go to: app Settings → Notifications → Call Sounds → Sound → And choose either 1) Zangi’s Default Tone 2) Your Device Default Tone (the ringtone of your device). If you change your device ringtone, you can also have it changed on Zangi.

You can choose who sees your status from the app Settings → Privacy → enable/disable Show My Online Status, Show When I’m Typing or Show Seen Status. Remember that you won‘t see Last Seen timestamps for people with whom you don’t share your own. You will, however, see an approximate last seen value.

Members can also join/leave in the middle of the call by tapping on Join or End Call. A maximum of 10 people can be in a group call for non premium users.

Our call quality is 720p resolution with photo-realistic colors and crystal clear voice. But you may be experiencing quality problems for one or more reasons. Here are quick fixes: - Switch to a better connection and ask the person you’re calling to switch to a better connection, because in p2p technologies one side connection quality affects both sides. - If your connection is stable and good quality but Zangi calls seem to not provide the full HD experience, check your Low Data Usage mode. Navigate to the Zangi’s Settings tab > Low Data Usage and switch off the mode for subsequent connection type. Low Data Usage mode forces the app to minimize the bandwidth consumption, which is used to stabilize calls in a fluctuating unstable connection environment. - The connection is unstable and fluctuating, like in airports, mass public events, forcing the app to adapt the quality frequently which may result in a frequent freeze-like experience. Navigate to the Settings tab and switch on the “Low Data Usage” mode for Mobile data and/or Wi-Fi. It will narrow down the bandwidth usage to a constant stable connectivity, which won’t give full HD quality but will make the video / audio uninterrupted and stable. - Turn off the video, and speak with audio if the quality is off. Also note that: sometimes calls won’t go through with a 2G connection, try calling with a connection higher than 3G.

To turn on your video tap on the screen and tap on the video icon. To turn off the video tap on the screen again and tap the video icon once more. If you’re seeing a black screen, the video might be put on the back camera mode. Switch from front and back camera mode by tapping on the switch camera icon or double tap on screen.
