Our IVR handles all media (RTP) directly and FS handles only SIP. When a call comes to FS with INVITE, in response we send 183 Session Progress with FS generated SDP (and RTP IP and port). In 200 OK, FS sends SDP with our application generated RTP IP and port. This works in most cases. Is there any way to invoke my application before sending 183 Session Progress, so that our application generated SDP can be sent in the 183 Session Progress? Prashant prashant.lamba(a)gmail.com

[Freeswitch-dev] IMPORTANT NEWS: blacklist.pl script not working because of infiltrated.net expiration
by Michael Collins 19 Nov '10

19 Nov '10

Hello all, It seems that infiltrated.net expired yesterday. This is the source of the data for our blacklist.pl script. The script pulls two files: http://www.infiltrated.net/voipabuse/addresses.txt http://www.infiltrated.net/voipabuse/netblocks.txt It uses these two files for building a better ACL that rejects known bad guys. Since these files are not currently available the script will receive bogus information and pollute the ACL. If you have run the blacklist.plscript prior to the failure and your system is working properly then please make a backup copy of your freeswitch.xml.fsxml file. This will contain the proper ACL nodes. DO NOT RESTART FREESWITCH OR RELOAD XML BEFORE BACKING UP THIS FILE! If you do then you will lose the information. I am researching this right now and I will update you as soon as I have some information. In the meantime if any of you have a freeswitch.xml.fsxml file with the blacklist info please zip and email me offlist a copy of that file and I will see if I can't extract the IPs and create a temporary workaround. I will also be updating the blacklist.pl script to do some error checking so that it doesn't pollute the ACL. Last item: if you have inside knowledge of what's happening with the VoIP Abuse project please contact me off list. Thanks, Michael S Collins

[Freeswitch-dev] media bug remove codec destroy crash
by Tamas Cseke 19 Nov '10

19 Nov '10

Hello, We have a segfault. It's not the newest code, so I didn't opened a jira yet. commit 84d897cb05079a4bfb3ed4ff98df0b5f666e0f70 Date: Thu Jul 22 01:23:06 2010 -0500 I advised to upgrade but it's not going so fast, and I think I found something so I ask before we do the upgarde I saw there were commits in media bug remove code, but I'm not sure it fixes it. http://pastebin.freeswitch.org/14554 The codec is destroyed in switch_core_media_bug_remove_all although switch_codec_ready said it's ready. I found that it could be removed in bug_remove or bug_prune too. In those functions the write lock is locked, but in remove_all it's unlocked before the codec destroy. So I think it somehow the bug remove and session hangup happend in the same time (I'm not 100% sure it's possible) and remove_all tried to destroy the codec that was already destroyed. I think the rwunlock sould go after the codec destroy in remove_all. Please check, and let me know if my theory make sense :) Thanks, Tamas

by Farhan Husain 19 Nov '10

Hello, I could successfully create audio conference by adding extension in dialplan. However, how can I create conferences dynamically? Can I use mod_event_socket for that? Is there any command to create a conference dynamically? Thanks, Farhan

[Freeswitch-dev] IMPORTANT: If you use "verbose events" then read this
by Michael Collins 18 Nov '10

18 Nov '10

Guys, Just an FYI for those of you who use verbose events in your event programming... Tony fixed a bug recently: http://jira.freeswitch.org/browse/FS-2851 The commit is here: http://fisheye.freeswitch.org/changelog/freeswitch.git/?cs=180f58a677a2ef49… If you have no clue what verbose events are for then you can probably ignore this. :) -MC

Brian, Maybe you misunderstood me... make runs well, as you can see in the pastebin: FreeSWITCH has been successfully built. When I type make install, the script just hangs on, cpu load becomes 100% and thats all... I can't even connect to the image using ssh, I can only restart the vm. Tha last command cause the hang was: ldconfig -n /usr/local/freeswitch/lib as you can see at pastebin... >but this has ZERO information Ok, but WHAT kind of information do you need? Sorry, I'm not a linux expert, please describe what other output do you need... Please help... Thhanks in advance... >I'm not sure if you're just not understanding us or what... but this has ZERO information that would indicate any sort of failure... was this the whole output or did you pick the parts >to pastebin? >/b On Nov 17, 2010, at 3:23 PM, rentmycoder rentmycoder wrote: > http://pastebin.freeswitch.org/14516 > > Is this enough info? > Do you need something else to analyse? > Any hint? > Thanks a lot... > > _______________________________________________ > FreeSWITCH-dev mailing list > FreeSWITCH-dev at lists.freeswitch.org > http://lists.freeswitch.org/mailman/listinfo/freeswitch-dev > UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-dev > http://www.freeswitch.org

[Freeswitch-dev] Verbose Events
by David Brazier 18 Nov '10

18 Nov '10

Hi All I want to get session variables on all events. I have tried using the "verbose-events" dialplan app but that isn't convenient to use when bridging. So I have set <param name="verbose-channel-events" value="yes"/> in switch.conf.xml & restarted to make sure. But I still don't see variables on all events, for example CHANNEL_CALLSTATE. In the source code, there are 3 related flags: CF_VERBOSE_EVENTS - the "channel flag" set by the "verbose-events" dialpan app SCF_VERBOSE_EVENTS - the "switch control flag", set by "verbose-channel-events" in switch.conf.xml SCSC_VERBOSE_EVENTS - used by "fsctl verbose_events" - actually SCSC_VERBOSE_EVENTS is only an internal name for the command - using "fsctl verbose_events" sets or clears SCF_VERBOSE_EVENTS In switch_core.c the SCSC_ flags are accessed via switch_core_session_ctl: SWITCH_DECLARE(int32_t) switch_core_session_ctl(switch_session_ctl_t cmd, void *val) { int *intval = (int *) val; int oldintval = 0, newintval = 0; if (intval) { oldintval = *intval; } if (switch_test_flag((&runtime), SCF_SHUTTING_DOWN)) { return -1; } switch (cmd) { case SCSC_VERBOSE_EVENTS: if (intval) { if (oldintval > -1) { if (oldintval) { switch_set_flag((&runtime), SCF_VERBOSE_EVENTS); } else { switch_clear_flag((&runtime), SCF_VERBOSE_EVENTS); } } newintval = switch_test_flag((&runtime), SCF_VERBOSE_EVENTS); } break; ... } if (intval) { *intval = newintval; } return 0; } If I read this right, the caller can use this to just get the flag without setting it by setting val to -1 initially. However, in switch_channel.c where it is deciding whether to do a verbose event: SWITCH_DECLARE(void) switch_channel_event_set_extended_data(switch_channel_t *channel, switch_event_t *event) { switch_event_header_t *hi; int x, global_verbose_events = 0; switch_mutex_lock(channel->profile_mutex); switch_core_session_ctl(SCSC_VERBOSE_EVENTS, &global_verbose_events); if (global_verbose_events || switch_channel_test_flag(channel, CF_VERBOSE_EVENTS) || switch_event_get_header(event, "presence-data-cols") || event->event_id == SWITCH_EVENT_CHANNEL_CREATE || event->event_id == SWITCH_EVENT_CHANNEL_ORIGINATE || ...) // then add the variables to the event Because this does "global_verbose_events = 0" it always clears SCF_VERBOSE_EVENTS. I could easily have misuderstood, and if anyone else has had success with "verbose-channel-events" please let me know. Cheers David
