When an incoming call is coming in, the phone rings, but there's no slide (or otherwise) to physically tell the phone to ring.
After the call/ringing is complete, the history shows the caller id etc...
I'm able to make outgoing calls.
I'm using IAX
The App used to work, however, I haven't used it in a few weeks and turned it back to active today.
I have the PRO version of the app and it appears to have updated to the latest version (on its own).
