Yeah it works pretty well, but it would be nice if the app stayed open after a call in case I want to make another call.

Also, slightly off topic, but using the built in RTCOMM SIP, is it possible to pull up the dialpad while on a call?

Finally, I know this is only a dialer right now, but is it possible for future versions to also display voicemail and contact information without having to go to the webpage?
