MizuDroid SIP VOIP Softphone

MizuDroid is a free, unlocked, professional SIP softphone from Mizutech.

The app doesn't include any VoIP service. You are free to configure it to be used with any SIP server or service provider.

Note1: You will need to have a SIP account to be able to use this softphone and calls to mobile/landline phones might cost you money. See your VoIP service provider for the exact terms and pricing.

Note2: The softphone might try to run in the background and request to ignore battery optimizations only if push notifications are impossible in your network, for example if your SIP server is on private IP and doesn't support push notifications.
