asterisk users - Oct 2006 - Unable to create/find SIP channel for this INVITE & Broadvoice

I've setup Asterisk to work with Broadvoice for both incoming and outgoing
calls.  I can make outgoing calls, but when I try to receive an incoming call
I see the following message on the console:

[date] NOTICE[8661]: chan_sip.c:13178 handle_request_invite: Unable to
create/find SIP channel for this INVITE

It's registered with Broadvoice:

Name/username              Host            Dyn Nat ACL Port     Status
sip.broadvoice.com/xxxxx  147.135.0.128               5060     OK (79 ms)

Here are my configuration settings related to Broadvoice, I've editted
out the auth_id and SIP secret.

pedantic=no
register => <auth_id>:<secret>:<auth_id>@sip.broadvoice.com

[sip.broadvoice.com]
type=peer
user=phone
host=sip.broadvoice.com
fromdomain=sip.broadvoice.com
fromuser=xxxx
secret=xxxx
username=xxxx
insecure=very
context=from-pstn
authname=xxxx
;dtmfmode=inband
;dtmf=inband
dtmfmode=rfc2833
dtm=rfc2833
canreinvite=no
qualify=yes

As you can see, I've tried both rfc2833 and inband for DTMF, but I doubt
it has any effect over this situation.

Dialplan:

[from-pstn]
exten => s,1,Answer
exten => s,2,Dial(100,30,tr)
exten => s,3,Hangup

I've googled for this, and the only reference I find to this error message
is in the source to Asterisk.  Any help would be much appreciated.

Thanks!

Hate to reply to my own message, and top quote, but the resolution here was just
to use sip debug.  Broadvoice was sending the call to a particular extension -my
phone number.  I simply added a Goto to my default dialplan (s) extension, and
it
worked.
