Jingle demo google talk

helllo

I’m trying to write a program to have a voice chat between google users

I have modified the demo.java ,but it doesn’t work

It throws an exception of “feature-not-implemented(501)”

My change:

(1)outgoing = jm.createOutgoingJingleSession("xxxx@gmail.com/Talk");

(another user logins from google talk client)

(2)server = “gmail.com”;

my smack version: 3.1.0

Is it the problem of device?

The icon of phone is invisible from google client.

So I can’t call him from google talk client

Could someone tell me how to let it work?

I’m a beginner of smack, so please give me more suggestion and more idea

thanks a lot
