Re: [SR-Users] Dialog module showing calls that have already been terminated

Hey Phillip, you probably forgot to keep the mailing list in CC, I'll do that for you.

So you are saying that before, you called dlg_manage() on INVITEs only but now, you need that function on both INVITE and BYE/CANCEL messages? That'd still qualify as a bug as the trigger to tracking the dialog (i.e., dlg_manage()) is required only once. After that, the dialog module makes sure that all dialog-related messages are properly processed. The only thing that's necessary for sequential requests to be tracked correctly is a call to loose_route() on such messages. If you are sure that your Kamailio configuration didn't change between 3.1.2 and 3.1.5 w.r.t. dialog tracking or anything that could affect it, I'd be willing to take a closer look at this issue (giving you can provide me with more information on your scenario, like call flow examples or similar).

Add client certificate checking against a CRL in opensips
by tomsc 20 Sep '11

20 Sep '11

Hi everyone, I'd like to check that a client certificat is revoked or not against a crl. Actually, opensips use context SSL_CTX. How can I do with this context? I do this change to load the crl : load_crl(SSL_CTX * ctx, char *filename) { LM_DBG("entered load crl\n"); X509_STORE *pStore = SSL_CTX_get_cert_store(ctx); X509_LOOKUP* plookup = X509_STORE_add_lookup(pStore, X509_LOOKUP_file()); if (!X509_load_crl_file(plookup, filename, X509_FILETYPE_PEM)){ LM_ERR("unable to load certificate file '%s'\n", filename); return -1; } LM_DBG("'%s' successfuly loaded\n", filename); return 0; } But I dont know how to add flags, is it the right solution? Thanks all -- View this message in context: http://old.nabble.com/Add-client-certificate-checking-against-a-CRL-in-open… Sent from the OpenSER Users Mailing List mailing list archive at Nabble.com.

Lazy evaluation in if expressions?
by Morten Isaksen 20 Sep '11

20 Sep '11

Does Kamailio use lazy evaluation in if expressions? Like if ($var(a) == 2 && $var(b) ==3) { ... } then $var(b) == 3 is only evaluated if $var(a) == 2 is true -- Morten Isaksen

directed media problem when video is included in sdp
by Juha Heinanen 20 Sep '11

20 Sep '11

when sems receives voice call invite from ua behind nat that has direction:active in its sdp, like this: Session Description Protocol Session Description Protocol Version (v): 0 Owner/Creator, Session Id (o): foo.bar 0 0 IN IP4 192.168.1. 68 Session Name (s): - Connection Information (c): IN IP4 192.168.1.68 Time Description, active time (t): 0 0 Media Description, name and address (m): audio 8500 RTP/AVP 18 4 112 100 101 0 8 106 Media Attribute (a): sendrecv Media Attribute (a): rtpmap:18 G729/8000 Media Attribute (a): rtpmap:4 G723/8000 Media Attribute (a): rtpmap:112 AMR/8000 Media Attribute (a): rtpmap:100 EG711U/8000 Media Attribute (a): rtpmap:101 EG711A/8000 Media Attribute (a): rtpmap:0 PCMU/8000 Media Attribute (a): rtpmap:8 PCMA/8000 Media Attribute (a): rtpmap:106 telephone-event/8000 Media Attribute (a): direction:active sems includes direction:passive in 200 OK and starts to correctly send rtp packets to the ip address/port of received rtp packets. however, then sems receives a voice+video call invite like this: Session Description Protocol Session Description Protocol Version (v): 0 Owner/Creator, Session Id (o): foo.bar 0 0 IN IP4 192.168.1.68 Session Name (s): - Connection Information (c): IN IP4 192.168.1.68 Time Description, active time (t): 0 0 Media Description, name and address (m): audio 8500 RTP/AVP 18 4 112 100 101 0 8 106 Media Attribute (a): sendrecv Media Attribute (a): rtpmap:18 G729/8000 Media Attribute (a): rtpmap:4 G723/8000 Media Attribute (a): rtpmap:112 AMR/8000 Media Attribute (a): rtpmap:100 EG711U/8000 Media Attribute (a): rtpmap:101 EG711A/8000 Media Attribute (a): rtpmap:0 PCMU/8000 Media Attribute (a): rtpmap:8 PCMA/8000 Media Attribute (a): rtpmap:106 telephone-event/8000 Media Description, name and address (m): video 8600 RTP/AVP 34 Bandwidth Information (b): AS:300 Media Attribute (a): sendrecv Media Attribute (a): rtpmap:34 H263/90000 Media Attribute (a): direction:active it does not include direction:passive in 200 OK and keeps on sending rtp packets to 192.168.1.68 even after receiving first voice rtp packet from public ip of the ua. is this a bug in sems or is it a bug in sr nathelper_k fix_nated_sdp("1") implementation, i.e., does that function place direction:active line to only one place, when it should place it in two places (in both voice and video media descriptions)? -- juha

Dialog module showing calls that have already been terminated
by Phillman25 Kyriacou 16 Sep '11

16 Sep '11

Hello I have been facing an issue where the dialog module is showing calls as being active when in fact the call has already been completed long ago and this is giving wrong number of concurrent calls on our SNMP work station (CACTI) when polling the data from Kamailio. I realized this only started occurring after i upgraded from 3.1.2 to 3.1.5, has anyone experienced the same issue? my config: ======== loadmodule "dialog.so" . . . . # ----------------- DIALOG MODULE PARAMETERS----------------------------------# modparam("dialog", "enable_stats", 1) modparam("dialog", "hash_size", 4096) modparam("dialog", "rr_param", "did") modparam("dialog", "dlg_flag", 4) modparam("dialog", "timeout_avp", "$avp(i:10)") modparam("dialog", "dlg_extra_hdrs", "NULL") modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "detect_spirals", 1) modparam("dialog", "db_url", "mysql://openser:openserrw@localhost/openser") modparam("dialog", "db_mode", 1) modparam("dialog", "db_update_period", 60) modparam("dialog", "db_fetch_rows", 500) modparam("dialog", "table_name", "dialog") modparam("dialog", "from_uri_column", "from_uri") modparam("dialog", "from_tag_column", "from_tag") modparam("dialog", "to_uri_column", "to_uri") modparam("dialog", "to_tag_column", "to_tag") modparam("dialog", "h_id_column", "hash_id") modparam("dialog", "h_entry_column", "hash_entry") modparam("dialog", "state_column", "state") modparam("dialog", "start_time_column", "start_time") modparam("dialog", "timeout_column", "timeout") modparam("dialog", "sflags_column", "sflags") modparam("dialog", "bridge_controller", "sip:controller@kamailio.org") modparam("dialog", "default_timeout", 7200) . . . . route { # MANAGE ALL DIALOGS #=================================================== if (is_method("INVITE")) { if(is_method("INVITE") && !has_totag()) { $dlg_ctx(timeout_route) = 12; $dlg_ctx(timeout_bye) = 1; } dlg_manage(); } Thanks Phillip

kamailio debian/ubuntu support
by Jon Bonilla 16 Sep '11

16 Sep '11

Hi all with the release of kamailio 3.1.5, I've done a small change to the debian repositories: Nightly builds of kamailio_3.0 branch have been dropped and the repository has been erased. There is no development in this branch and it has no sense to keep nightly builds for it. Those (few) people using kamailio_3.0-nightly repositories are advised to move their sources.list to the stable 3.0 repository of upgrade to 3.1 or master branches. kamailio 3.0 will continue to be packaged if any new stable version is released for etch, lenny, squeeze and lucid. For 3.1 branch, nightly builds and stable repos will be provided for lenny, lucid and squeeze When the time for 3.2 (master branch at the moment) comes, I'll add Wheezy support. Not sure about Ubuntu distro support. Should we add support to Ubuntu 11.10 or wait until the lts 12.04 is released? Any opinions welcomed cheers, Jon
