Priority: 5 Private: No Submitted By: xhu xhu (xhujohnson) Assigned to: Nobody/Anonymous (nobody) Summary: SIPv6 UA can't receive a 423 (Interval Too Brief) response

Initial Comment: SIPv6 UA can't receive a 423 (Interval Too Brief) response from openser-1.3.4-12.fc13.i686 SIPv6 Registrar Server when expiration of a REGISTER request is less than a registrar-configured minimum.The details can be seen as follows. Is it a bug or can be resolved by modifying configuration file? 1 Test topology:

NUT(REG && PX) UA11 UA12 DNS | | | | IP : 3ffe:501:ffff:50::50 3ffe:501:ffff:1::1 3ffe:501:ffff:2::2 3ffe:501:ffff:4::1 aor-uri : ss.under.test.com UA11@under.test.com UA12@under.test.com contact-uri : UA11@node.under.test.com UA12@node11.under.test.com

2 the tcpdump file can be seen in "SIP Registrar- Expiration of REGISTER request less than a registrar-configured minimum" attachment

3 openser-1.3.4-12 configuration file can be seen in openser.cfg attachment. I have added the following block into the openser.cfg " modparam("registrar", "default_expires", 3600) modparam("registrar", "min_expires", 60) "

Message: Hi!

1. Openser 1.3 is rather old and not supported anymore. Anyway, the behavior has not changed in newer versions.

2. Openser/Kamailio/sip-router does not have an implicit mechanism to send 423 - it uses a different approach. It just overrides the user-provided expires value and set a different one. Take a look at the 200 OK response - the Contact header has a different expire value (660) then the requested one (30).

3. if you really need 423, you have to script it. e.g. in Kamilio 3.0 Syntax: if ($hdr[Expires] < 3600) { append_to_reply("Min-Expires: 3600\r\n"); sl_send_reply("423","Intervall to short"); exit; }

4. For such discussions please use the kamailio mailing list
