[Asterisk-Users] D-link DPH-80 (SIP) call to asterisk problem

[Eugene Crosser]

Hello gentlemen, I am new here.

I have a D-Link DPH-80S SIP phone (it's a non-US model), and I am trying
to make it work with Asterisk.  I tried versions 1.0.7 and yesterday's
CVS and the behavior is the same.

The phone registers with no problem, and can accept calls.

But when I try to make outgoing call, there is a series of invite
requests from the phone, to which asterisk responds with 407.  Comparing
logs with that of a soft phone, the difference is as follows:

Softphone
p: INVITE w/o Auth
a: 407 auth required
p: ACK
p: INVITE with auth
a: 200 OK
- all of these share the same Call-ID.

D-link:
p: INVITE w/o Auth
a: 407 auth required
p: ACK
p: INVITE with auth and new Call-ID
a: 407 auth required
p: ACK
p: INVITE with auth and new Call-ID
a: 407 auth required
p: ACK
p: INVITE with auth and new Call-ID
- et cetera

Apparently when Call-ID is new asterisk no longer matches the nonce that
it sent to this phone (check_auth is called with NULL third argument).

This does look like a bug in the phone firmware.  However, the phone can
successfully initiate calls via several commercial and community
providers.  I tried iconnecthere.com and voipuser.org and it works!

Now, the question: could it be possible to make the phone work with
asterisk?  Any ideas?  I can send the log on request (it is rather big).

Thanks.
Eugene

P.S. I also have a problem calling from asterisk to iconnecthere but
I'll report it in a separate message.
