[Ekiga-list] Ekiga cannot register with ekiga.net - Asterisk can

[Bent <bbagger gmail com>]

Hi

I have been unsubscribed to this list for a while so some
advertisements may have posted regarding my problem. There is,
however, not anything like it in the archives as far as I have been
able to determine.

Anyway, my problem is stated in the subject line. Here are some details:

Asterisk runs on my gateway/firewall. My ekiga softphone (which is
2.0.12 - the latest issued by Gentoo) runs on a workstation behind the
firewall. I use no proxy, but the firewall (another box running Gentoo
Linux) has the SIP ALG enabled.

Asterisk registers fine with ekiga.net:

bent yosie ~ $ tshark -r ekiga-asterisk.trace
Running as user "bent" and group "users".
  1   0.000000  86.48.49.19 -> 86.64.162.35 SIP Request: OPTIONS sip:ekiga.net

bent yosie ~ $

whereas Ekiga the softphone doesn't:

bent yosie ~ $ tshark -r ekiga.trace
Running as user "bent" and group "users".
  1   0.000000  86.48.49.19 -> 86.64.162.35 SIP Request: REGISTER sip:ekiga.net
  2   0.009675  86.48.49.19 -> 86.64.162.35 SIP Request: SUBSCRIBE

  3   0.023790 86.64.162.35 -> 86.48.49.19  SIP Status: 606 Not
Acceptable    (0 bindings)
  4   0.033924 86.64.162.35 -> 86.48.49.19  SIP Status: 202 OK
bent yosie ~ $

The full traces are available here (for about a month from now):

Several questions arise:

1. Why do I get '484 Address Incomplete' when my Asterisk asks for options?

2. Why does my Ekiga get a '606 Not Acceptable' when it tries to register?

3. Why is the subscribe accepted '202 OK'?

Kind regards,

Bent
