asterisk users - Mar 2005 - BroadVoice - "Failed to authenticate on INVITE" error

I'm experiencing a "Failed to authenticate on INVITE" error (see
output below) whenever I try to MAKE a call through the Broadvoice
account.  I noticed some others had the same problem but it went away
when they rebuilt Asteris w/ a new version.  N such luck for me!

I'd be grateful for any assitance.  Here's what I've done so far:

1) I downloaded the latest stable version of Asterisk and compiled it
(27-Mar-05).
2) I updated my conf files as per the Broadvoice web site (see below)
3) I CAN make and recive calls through the Broadvoice account using X-Lite.
4) To avoid typos, I used cut and paste in sip.conf to copy the phone
number and password from the register line  to the
[sip.broadvoice.com] section
5) When I run Asterisk:
   i)   The Broadvoice account registers OK
   ii)  I can receive calls on the Broadvoice account
   iii) I CANNOT make calls through the Broadvoice account.  When I
do, my computer freezes up but eventually comes around a while after I
hangup and warns - Failed to authenticate on INVITE to '"asterisk"
<sip:8145551212@sip.broadvoice.com>;tag=as4a325b3a' (see below)

Any ideas?

Finally, I'm still unclear about assigning an extension to the
Broadvoice account as part of the  registration line (see where I
commented out ;/3003).  What does it do?  I rely on the context
defined under the [sip.broadvoice.com] section.  What do you gain by
assigning an extension in the Register line?

My conf files and the Asterisk output are below.

Thanks,
Jewel
