How to add username in STUN response

[frogsir@xxxxxxxxx (frogsir)]

In order to match the lastest ICE draft, I need to add username attributes
in STUN response message.

I hacked PJSIP version 1.0.2.

in file stun_session.c  and function:

static pj_status_t apply_msg_options(pj_stun_session *sess,
                     pj_pool_t *pool,
                     const pj_stun_req_cred_info *auth_info,
                     pj_stun_msg *msg)


I added an "if" block for STUN response message:

*    /* Create and add USERNAME attribute if needed */
    if (username.slen && PJ_STUN_IS_RESPONSE(msg->hdr.type)) {
    status = pj_stun_msg_add_string_attr(pool, msg,
                         PJ_STUN_ATTR_USERNAME,
                         &username);
    PJ_ASSERT_RETURN(status==PJ_SUCCESS, status);
    }*

the username is not the same as the one in the STUN request. The length of
the string is more than 1000 char.

then I try to use "sess->cred.data.static_cred.username" as the username,
result is even worse.

Can anyone help me ? Thanka a lot.
