[Serusers] TOS question - should see 0x10, am seeing 0x00
by Ravindranath Gummadidala 01 Jun '07

01 Jun '07

Hi, I am using SER 0.9.4. I want to make sure that all SIP traffic from the SER is marked with a specific DSCP value. I grepped in the src and found that SER already does this for both TCP and UDP sockets using a setsockopt with a value IPTOS_LOWDELAY (0x10). However, a packet trace I captured shows that the TOS field is 0x00. It did not look to me like the TOS setting code was featurized, so I am not sure what is going on here. Anyone have any ideas. Regards, -Ravi.

[Users] acc::log_extra question
by Will Quan 01 Jun '07

01 Jun '07

Hi all,I noticed that if I request to log a field that was not present in the SIP message it doesnt log 'n/a' anymore.Is this design intent ?Here is an example:/* I would like to see diversion in log */modparam("acc", "log_extra", "div=$di")However if not present, later I get an error in the logs:xl_get_diversion: ERROR cannot parse Diversion headerThe 1.1.x behavior was to not generate that error while the actual ACC had a value of 'n/a'.Regards,Will

[Users] "invalid cseq for aor" in replicated registrations
by Papadopoulos Georgios 01 Jun '07

01 Jun '07

Hello all, I have a question about replicated registrations. Server1 sends an authenticated REGISTER to server2. The script looks like: if (method=="REGISTER") { if (src_ip==server1) { # Handle replicated registrations. No need to authenticate, just save. if (!save("location")) sl_reply_error(); } else { # Digest authentication if (!proxy_authorize("", "subscriber")) { proxy_challenge("", "0"); return; } if (!check_from() | !check_to()) { sl_send_reply("400", "Bad Request"); return; } if (!save("location")) { sl_reply_error(); } # Send a copy of this registration to the other proxy t_replicate("sip:server2:5060"); } return; } On server2 I get this message: ERROR:registrar:update_contacts: invalid cseq for aor <...> But I don't have the same message on server1. If the cseq is invalid then how come server1 saves it successfuly and then replicates it to server2? thank you George Disclaimer The information in this e-mail and any attachments is confidential.

The latest stable version 1.2.1 should be fine. Look at the migration notes in the wiki for update hints, http://openser.org/dokuwiki/doku.php As you going from 1.0 to 1.2, a complete new installation would be probably easier. So uninstall the old openser, backup your database tables, install the new and migrate the data to the new installation. You find informations about the necessary changes in the mentioned documents.

[Serusers] Preserve DSCP marking
by Ravindranath Gummadidala 01 Jun '07

01 Jun '07

Does SER have support for preserving the DSCP markings of (incoming) SIP messages it processes before sending them out? Or is this something one would need to change the SER source code for? I searched in the archives but could not find anything relevant. Regards, -Ravi.
