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, including SMS sent while the phone was off (some apps never pulled those down). I'm a fan.

Thank you for your review, Sam. We haven't tested text messages with, great to hear that it works!

The biggest problem is you really can't leave this on. I hate that Android got rid of the native SIP dialer because this client does not come anywhere close. If you leave the app running in the background overnight it will drain your battery. It's completely unacceptable for a sip client for people who run their own voice service. Just overnight my battery went from 65% to 1% between 11:00 at night and 5:30 in the morning with the app taking a whopping 40% of the battery drain.
