Assistance Requested Configuring CSipSimple

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 !

I have CSipSimple working well on an HTC phone.....although it exhibits some of the issues you describe when used over wifi that's the same subnet as the ATA.......which is to be expected. If I use it on wifi away from home, it works fine. I don't think I changed any of the codec setting from defaults.
