About this app

Sipnetic is a free VoIP softphone based on the SIP protocol. It allows you to connect to your VoIP provider, cloud PBX, or an enterprise telephony server.

⚠️ Important note
Sipnetic doesn’t offer a VoIP service. To use Sipnetic you need an account from a SIP service provider. When you use the New Account Wizard, make sure you already have the server address, login, and password.

Ratings and reviews

Had to stop using Sipnetic due to heavy battery use - up to 30% in one day. My phone was in constant danger of not lasting even one day just from normal use and this app. Functionally, the app works and sends text messages using an SIP Simple connection to my VOIP provider, and call quality is fine. But there is no getting around the huge battery use. I have incresed the ping setting as someone else suggested but it does not help. Sorry but the battery drain overwhelms everything else.

Edited: I started getting 3 beeps and no audio during calls, but a reinstall fixed it. ALSO - for those with battery issues, try increasing registration time to 15 minutes and TCP/UDP ping to something like 300 seconds. I didn't see any adverse affects from doing this. Battery way better! Original: Underrated! Fast. Reregisters quickly when switching networks. SMS works on VoIP.ms, including SMS sent while the phone was off (some apps never pulled those down). I'm a fan.

Polished and very reliable app that does what it intends to do. Unlike some other apps, it's not aggressively trying to monetize its users, with the vast majority of the features included for free; there are only a few paid addons that are reasonably priced. However, due to not having push support, it is quite a battery hog. I'll give a solid 5 stars once this is added, although I know it can add a significant layer of complexity.
