MoSIP Mobile Dialer for Android

Brief overview

MoSIP Mobile Dialer is a free mobile application from Voxvalley Technologies Ptd Ltd that enables Voice over Internet Protocol (VoIP) calls on smartphones. The app is designed with a simple interface and uses standard audio technologies to keep conversations clear when conditions allow. It works through your mobile service arrangements to place calls, including to recipients who don't have the same app installed.

Getting started with the app

• Request your account details (Brand PIN, username, password) from the service provider that will route your VoIP calls.
• Register in the app using your mobile phone number and then enter the credentials supplied by your provider.
• After configuration completes, start calling immediately — you can dial regular numbers as well as other app users.

Network compatibility and audio performance

MoSIP supports a variety of internet connections:

• 5G, 4G/LTE, and Wi‑Fi are all supported, so you can switch between networks based on availability.
• The app uses common VoIP codecs and connection methods intended to preserve voice clarity under good network conditions.

Known limitation: there is a reported issue where the incoming audio may drop out when the device screen locks or times out. This affects the remote side’s audio and developers are expected to address it in a future update.

Advantages and things to consider

• Easy onboarding: quick registration and simple dialing controls make it approachable for new users.
• Cross-network use: works over cellular data and wireless networks, giving flexibility in how you connect.
• Compatibility: can place calls to non-app users, so it can replace or complement traditional phone lines.

Caution:

• The screen-timeout audio problem can disrupt calls when the phone sleeps, so keep the screen active or monitor for updates until it’s fixed.

Summary and recommendation

If you want a straightforward VoIP alternative to conventional voice calls, MoSIP Mobile Dialer is worth trying. It’s free, simple to set up, and supports modern mobile networks. Keep an eye out for bug fixes related to audio when the device locks, but otherwise it’s a handy option to test for replacing or supplementing regular phone service.
