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
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.
Back in my good books Since last update I didn't get any crashes (used to be daily) so I'll give a few more stars. Definitely the call quality is the best among Android clients. ...and I probably tried most of them./Update: just when it stopped crashing, development is discontinued...nice.
Problem with auto hangup New version +tls does auto hangs up after the receiver picks up the phone. However i can receive encrypted calls from other callers if they still have previous ver. Looks that new ver makes some problem or interprets the config in other way. For months was ok.
