great free open source no ad voip app! Dear developers! 1)Please update the list of servers of voip.ms. 2) Also, it is easy to kill the app from the recent app list. The service (or what is it called in Android) keeps running. If you run csipsimple again, it won't register on your server. Would be nice if this was fixed. 3) echo cancellation doesn't work on voip.ms lately. The other party hears their own voice. This doesn't happen on Zoiper and others. Thank you!
I love it. I'm using this at home connected to my local Asterisk server using G 722 protocol over Wifi and it is wonderful. It is a brilliant piece of software thank you so much. Integration with the dialer in my Samsung S5 is perfect. Knocked a star, app crashes on Intel proc dell venue 8
Very good open-source SIP client CSipSimple and Sipdroid are both excellent. CSipSimple is probably heavier but has a slicker UI and a better integration with the OS. Didn't notice any major difference in terms of call quality. I've been using CSipSimple lately... **Update:** not sure the development is still active -1 star
Best SiP app I have tried I use Sipgate for my work phone, and wanted to run it through my mobile rather than a softphone on the PC. After trying a few solutions, including the built in sip functions, this seems to work the best. My only real problem is when connected to a WiFi hotspot, but not logged in to it, the select routing option when you try to make a call freezes and prevents me from even using my mobile provider, meaning I have to either disconnect the WiFi or log in to it before I can make *any* call
Solid with Caveats This is a solid app. The downside is it hasn't been updated since 2014 which makes me worry about it's support going forward, however it is open source. There are tiny issues here and there but nothing showstopping. Big annoyance is I can't paste a phone number.
Works fine, but no search in contact list Seems to work fine with my VoIP account. One problem I have with it is that you can't search in your contact list, which is very inconvenient. On the other hand, the native phonebook integration (so that you're offered to call using CSipSimple instead of your standard GSM phone) does not work well either - you need to use its custom integration, but that break other services using the native integration. A last minor annoyance in a warning toast message when exiting the app.
* Hot fix for android 5.0
* New wizards
* intel x86 support (with new playstore requires to bundle in same application)
