[Asterisk-Users] Asterisk returns 484 ADDRESS INCOMPLETE for incoming SIP calls

I'm new to asterisk and need some help with getting a SIP connection
working.

I am trying to establish a termination point/DID number in another
country.  I am currently running Asterisk CVS-HEAD.  My foreign provider
uses SIP and authenticates via IP address.  I am not required to
register my SIP connection in order to send or receive calls.

Can someone help me with how to understand the error I see below with
receiving incoming calls?
My asterisk box is behind my IPCop firewall.  The current configuration
works fine for
outgoing calls, but has problems with receiving incoming ones.

My current configuration looks like:

[general]
context=default
bindaddr=192.168.0.4
srvlookup=no
disallow=all
allow=ulaw
localnet=192.168.0.0/255.255.255.0
externip=65.87.XXX.XXX
nat=no
fromdomain = mydomain.com

[200.XXX.XXX.XXX]
type=peer
secret=asterisk
host=200.XXX.XXX.XXX
allow=ulaw
context=outgoing
dtmfmode=rfc2833
insecure=very

[from-200.XXX.XXX.XXX]
type=user
host=200.XXX.XXX.XXX
allow=ulaw
canreinvite=no
context=outgoing
insecure=very

Outgoing calls seem to work fine, but there is no indication of any
incoming calls in the SIP debug
information when I call the DID number externally.  I have all the SIP and
RTP port forwarded to my Asterisk box in my firewall and don't see
anything in the firewall logs.

I do see the following 2 entries back-to-back in an ethereal dump.  I
don't know enough about
SIP to know if the DID side is sending a bad INVITE or if Asterisk is not
handling the INVITE
correctly.  I cannot tell if the DID side is not responding back with more
address detail or if my Asterisk box is dropping the connection right
after the 484 response.

Can someone help?


Thanks,
Frank
