Linphone

There is a bug in the latest version: cannot call a contact, have to enter number directly, due to space character in the number

Push notification won’t work. If the phone is on standby or the app is in background. Well this is useless

Tried 3 different phone numbers to create account but no error message or anything… just sat there.

No voice or audio when we make call. Also the other person cannot hear

Terrible update!!! You can't configure the account while switching between the apps to get the username and password. As soon as you got back to the app it goes back to the original screen!!

Have yet to make it connect with my SIP provider. Interface has some showstopping bugs around account configuration, such as the inability to save user informattion (such as the ID) or network settings (such as the port). If your provider's port isn't the app's default of 5060, you're going nowhere. Have tried install and reinstall but to no avail. iPhone 5S.

Easy to setup and calls work OK, but it crashes when I try and call from my contacts

This app works like a charm. The setup wizard is so simple, it's a shame other softphones are as easy.

I like it, but it fails my five star rating due to three things 1) the UI being only OK when it could have a bit more polish and 2) it only works if the app is running on the front, it won't run behind the scenes and finally 3) I thought this would work well with FreePBX and it does for extension to extension, but crashes when accepting a transferred external SIP call. Oh and free support is not easy to get/find ;( Great potential though..

Nice application! Only issue is that when my phone is on stand by my incoming number to my sip account doesn't ring on my phone unless I launch the application. Also SMS not included yet?
