First, it's probably a good idea to modify your initial INVITE slightly:
you sent (in part):
INVITE sip:[EMAIL PROTECTED] SIP/2.0
Call-ID: [EMAIL PROTECTED]
CSeq: 105 INVITE
From: <sip:[EMAIL PROTECTED]>;tag=1157360056
To: <sip:[EMAIL PROTECTED]>
One problem with this is that if the user does not answer, it will roll
over to voicemail. You can prevent that by including a parameter in the
target address:
INVITE sip:[EMAIL PROTECTED];sipx-noroute=voicemail SIP/2.0
Call-ID: [EMAIL PROTECTED]
CSeq: 105 INVITE
From: <sip:[EMAIL PROTECTED]>;tag=1157360056
To: <sip:[EMAIL PROTECTED];sipx-noroute=voicemail>
It would be a good idea to put some kind of display name on the From
header of the INVITE for this: "Join Conference <name>" or something...

The problem is that a blind transfer must be authenticated, and you
didn't respond when the proxy challenged you. The response to the REFER
was:
SIP/2.0 407 Proxy Authentication Required
From: <sip:[EMAIL PROTECTED]>;tag=1157360056
To: <sip:[EMAIL PROTECTED]>;tag=BBB30712-8850DD5
Call-Id: [EMAIL PROTECTED]
Cseq: 106 REFER
Via: SIP/2.0/UDP
47.16.91.3:5180;branch=z9hG4bKcac72e16efa84b8c5cf65b8b8a866bf9
Proxy-Authenticate: Digest realm="us.nortel.com",
nonce="a58b7d40e39911ceb60c8170deaa857348cffb9d"
Server: sipXecs/3.11.6 sipXecs/sipXproxy (Linux)
Date: Tue, 16 Sep 2008 18:31:57 GMT

which is an authentication request. You need to provide credentials to
your user agent so that it can authenticate the request.
I suggest that the authentication be that of the user who is creating
the outbound conference request - whoever logged in on the web interface
to request that the new user be invited into the conference.
