This app works but you need to configure it properly

I downloaded iSip and it didnt work properly; Audio was so choppy that it couldnt be used (even on the same network than our Asterisk Server). Also under some conditions and I only got one way audio. I spent a complete day doing several adjustments and debugging the protocol to check what was happening. The application is now working fine (audio is good; Not excellent, but good enough). If you are planning to use this application; You must have really good understanding of VOIP and what is happening under the hood. For example; I am not a big fan of iSIP VAD implementation, I had to turn it off. Remember to set the stun servers if you are planning to use it behind a NAT; there are a few free stun servers on the internet. PUSH did work OK to me; although I cant answer the call when receiving the notification. IMHO there is room for improvement on this app. Buy it *ONLY* if you really know SIP protocol and you are willing to spend some time to configure/debug it to make it work correctly on your enviroment.
