Just good, just works. Using free version. 4 stars just because it doesn't support g729. Also, lacking Brazilian Portuguese translation. Went for paid version because of call transfer feature. Much cheaper than Zooper, and as good as, even the free version.

Very good app, better than others, IMO. But it has two issues with my Samsung phone with Android 14. 1 - Huge echo with loudspeaker use. 2 - It disappears from running in the background after some time, I mean a couple of hours, though it has all battery permissions.

My inability to connect to freepbx turned out to be an internal firewall setting on freepbx which I thought I'd tried disabling but obviously didn't. As I said originally, connection to sipgate was flawless, and now connection to freepbx server equally great. Support was excellent. App is brilliant. Happily give both 5*s after ~4 days testing ... and I almost never give more than 4 to anything.

nice enough app. just a few things... can you not hide it from recent apps? filling in my account details took ages as when i switch to chrome sipnetic forgets whrre i was in the add account process and i have to start again. secondly, can you increase the verbosity of the error messages? "failed to register" isnt much use.

The app works, but when used with a sip on a LAN, it consumed over 11% ofy battery on a day where i was never ony work LAN, so it could neve connect. When I emailed them about taking this battery consumption to near zero by watching android network state changes, they said they cant (which is wrong) and they recommended i manually quit the app everytime i leave work. This is nonsense.

Just tried it. It's Ok, seems to work Ok for now. Simple. There are bugs and problems which don't make it on par with its main competitor zoiper though. The biggest for now is when I start entering a number it doesn't match it with contact list because of characters like spaces present in the number in system contact list. It should normalize numebrs when matching them. I guess this is the cause of others' complaining sipnetic didn't match incoming calls to names in contact list.

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.

Sorry if 3 seems harsh - but I feel it's fair. it's a VERY good start, audio is excellent, but there's a few issues: 1) Bluetooth Audio Buffering after call end (on-off-on-off - no problem other apps) 2) PTT button is of HUGE personal interest for a Joint radio / telephone capability - but couldn't make it work, 3) neither prices of addons, nor detailed feature lists for each addon so you don't know what you're committing to 4) no R button (maybe that comes as a value add ?) 1 to watch though.

Great app. Works very well from my Honor Play/Huawei phone. I had to change the application settings in the phone settings to allow it to run in the background. I like this app because it's well laid out and easy to use. The only feature I miss is that it does not seem to support an ad-hoc three way call (i.e, put one caller on hold, dial a second person and then conference them both in.) For some reason, pressing the button on my bluetooth headset to answer the call does not work. Instead, Sipnetic stops using bluetooth and switches back to the handset. The headset is still paired with the phone though. Means I can't answer a SIP call with the phone in my pocket. Would be useful feature to associate a contact with a sip account, or a number prefix to dial to use a given account, rather than having to switch accounts before calling a contact.

Simple to use, a modern interface, and seems to work very well. Because it doesn't use a push proxy it has to run in the background, but I found the battery consumption to be OK, and it's easy enough to hide the slightly irritating notification in Android 10. After 24 hours, the battery in my one year old Moto One Zoom fell to 36%. During that time I'd made about 40 minutes of regular voice calls and a couple of minutes of calls using Sipnetic. So of the 64% battery used, Sipnetic accounted for 5%. Mobile network standby used 19% and the screen 14%. Phone idle used 6%, Android itself 3%, and my Fitbit 3%. Compared to the other apps it is relatively high, accounting for about 9% compared to 7% for 43 minutes using Facebook messenger and 8% for 45 minutes using Chrome (but of course, Sipnetic was running for 24 hours). So in summary, I think it's great, and the battery usage concerns are minimal. My only suggestion so far would be the ability to specify a "quiet time" (e.g. overnight, when you probably don't want it ringing anyway), during which it could drop off the network and use even less power - even better if this is automatic when "Do Not Disturb" mode is activated on Android.

I use this app with Asterisk and have done for a while now. Absolutely no issues, and having tried many alternatives, this is by far the best. Does exactly as it says on the tin. I hope no major changes are ever made to this app because it is already easy to use, easy to configure, and so reliable. I use secure TCP to keep power consumption down and I get a good 2 days out of 1 charge on my Moto 200 pro. Thanks guys.

Good, well crafted app. I have several VoIP accounts and this app registers to all of them with no fuss, whereas Zoiper failed most times. Only suggestion would be to make the dialer more obvious and accessible, rather than just on contacts screen. Keep up with the good work!

Good app overall. I have been using it exclusivley for a few months now mostly because I wanted multiple accounts. I find the 'look and feel' very nice. Every time I email with a question the response is always in a reasonable time and the answers are helpful. I have tried other apps but Sipnetic seems to be the best fit for me. I like Zoiper as well and GS Wave is okay but I prefer Sipnetic now. I like that it is being actively developed and the Sipnetic team seems to take feature requests seriously.

Would like to see a couple of changes: * When in a call, would be good to see a line showing digits dialled when in a call. For instance when accessing voicemail and you have to enter a password or selecting other mailboxes. Apart from that, a great app. [edit] I'm Running Android 7 with Nova Launcher which supports widgets. Would it be possible to add the capability to support widgets to the app? Would be great if we can have a fast key to dial the PBX voicemail (*97) for instance.

App looks good but I'm unable to stay connected to my SIP provider. After filling in all details, my app registers for about 30-45 seconds (I can even make a quick call), but then "unregisters" and goes offline... I'm still fiddling with settings to see if I"m missing something obvious and will edit review if I do solve this.

the app is very well structured, takes away the complexity of SIP configuration with preconfigured settings for many providers, but unfortunately the high battery drain has meant I had to disable it on my pixel 8 pro. I hope this can be solved somehow because otherwise it's 5 stars from me

Easy and simple to use. Works well. Easily connected to my voip account. But... Very heavy on battery usage. In the past 24 hours it used 53% of the power. The entire Android system used 27% in the same period. Great if you don't mind recharging your phone frequently. >>>> Following on from the reply (8 Feb 2021) from IPTON: Thanks for responding. Actually I thought your VOIP app was excellent and it was only the power usage that prevented me from continuing to use it. If this problem is solved I will definitely be back. Your app has a very clean and simple interface - just what I wanted. Good luck.

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.

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.

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.
