So CSipSimple is as easy as the name implies. I have the Android app installed on my Samsung Galaxy S 2 and I get as far as placing the call. The other side picks up can hear my voice with a long series of echos and cannot respond (if they do I cannot hear them).

I have been trying to research the issue and find it MAY be that I do not have the correct SIP Coded chosen to interface with VOIPO SIP servers.

If anyone has had success configuring this app I would appreciate any input you could provide. Also, if you know the VOIPO preferred Codec, please let me know.

Thanks !
