Professional, highly adjustable!
Used this application in various network scenarios on wifi and 3g over long time, very reliable!
Configuration options amazing, highly adjustable to server requirements as well as powerful telephony comfort features.
Novices should read the documentation (iPhone guide pdf) which is well-written and answered all questions I had so far.
