I recently lost my setup (bad drive) and I'm now trying to get my setup back. I have Asterisk setup to a BT100, a Cisco 7960 (7.2 SIP) and an SPA3000. I can call the phone extension, I can call from the phone on the SPA to other extensions and I can call out to the PSTN. What I can't do is to call from the PSTN to through the SPA to Asterisk. It rings twice then I get fast busy. I have the SPA wait for the caller ID info (the reason it rings twice). What I've got is as follows:

registry=>pstn:pstn@spa.uucp:5061
  
[pstn_in]
  username      = pstn
  secret        = pstn
  type          = user
  host          = spa.uucp
  port          = 5061
  context       = from-pstn
  mailbox       = 2202
  nat           = never
  dtmfmode      = rfc2833
  canreinvite   = yes
  qualify       = yes
  insecure      = very
  disallow      = all    ; need disallow before we can allow
  allow         = ulaw
; 
[pstn_out]
  username      = pstn
  secret        = pstn
  type          = peer
  host          = spa.uucp
  port          = 5061
  context       = to-pstn
  from_user	= pstn
  nat           = never
  dtmfmode      = rfc2833
  canreinvite   = yes
  qualify       = yes
  insecure      = yes
  disallow      = all    ; need disallow before we can allow
  allow         = ulaw
;

My dial plan on the SPA looks like this:

(S0<:s@asterisk.uucp>)

What I see on the Asterisk console is :

May 17 23:36:29 NOTICE[11306]: chan_sip.c:10326 handle_request_invite: Failed to authenticate user xxxxxxxxxxxxxxx <sip:1xxxxxxxxx@asterisk.uucp>;tag=blahblahblah

In sniffer I traces I see a 407 (Proxy Authentication Required). I've also noticed a 401 (Unauthorized) for the phone on the SPA. What am I configuring incorrectly.

I'm using Asterisk 1.2.7, previously I was using 1.2.0.
