Thank you for your reply.
There is an update:
If I configure by web interface a new IAX account, it works fine, but by code not.
Here the code I changed, I used the Zoiper sample page.
function OnZoiperReady(phone)
{
...
Account = Zoiper.AddAccount("Sample", "IAX");
Account.Domain = "VoipServer";
Account.Host = "VoipServer";
Account.CallerID = "VoipAccount";
Account.UserName = "VoipAccount";
Account.Password = "VoipPassword";
...
}
[edit]
Now it works, just commented
//Account.Domain = "VoipServer";
Thank you
