[Freeswitch-dev] nolocal exports from dial plan
by Dino Korah 25 Nov '10

25 Nov '10

Guys, When I export a variable as nolocal, is it intended to prefix "nolocal:" for that variable on A, when that appears in the CDR? Or is it a glitch? Ref: src/mod/applications/mod_dptools/mod_dptools.c line 889 Here if you check, the export seems to ignore the local variable altogether. I am quite new to freeswitch; any help much appreciated. Many thanks, "dk"

[Freeswitch-dev] stfu jitterbuffer in FS
by Jyotshna Cherukuri 15 Nov '10

15 Nov '10

Hi, I enabled Jitterbuffer in FS for A leg of the call and when I set up packet loss simulation(4%) on my end client I expected FS to tag the lost packets as SFF_PLC but its not .I rather see the below code being executed . Could you please explain what this code does in stfu.c? i->miss_count++; if (i->miss_count > 10 || (i->in_queue->array_len == i->in_queue->array_size) || tried >= i->in_queue->array_size) { i->running = 0; i->interval = 0; i->out_queue->wr_len = i->out_queue->array_size; return NULL; } Any help is greatly appreciated Thanks Jyotshna

[Freeswitch-dev] VLAN support in sofia module
by Adam Kuśmirek 15 Nov '10

15 Nov '10

Hi All I would like to run FreeSwitch as SBC in my network. I have architecture with all clients connected via separate vlans. It gives me possibility to use one ip address for all clients, but I need FS sofia profile to bind to specific interface (eg eth0:20 vlan 20) and global ip address. As I see, for now sofia module allows to bind to ip address only. I looked quickly to sourcees and it seems that this is limited by sofia library. Of course i may be wrong because I'm new to FS and didn't have time to analyze sources. Please, write some words on this topic. Do you have plans to implement vlan support in FS. I know that AcmePacket Net-Net gives such feature. Don't know any open voip solution with this iplemented. Regards Adam

[Freeswitch-dev] Getting DTMF from channel.
by Paulo Rogério Panhoto 09 Nov '10

09 Nov '10

Hi, I'm writing a module that allows playback of MP4 video files (with libmp4v2). The playback itself is made by two functions ready to run on separate threads (though, audio runs on current thread and video runs on a separate one). At this point, I'm trying to implement dtmf cut-through. After some research (I checked out mod_dptools.c and switch_ivr_play_say.c) and this code was my best guess -- it runs on the audio stream: if(switch_channel_test_flag(pt->channel, CF_BREAK)) { switch_channel_clear_flag(pt->channel, CF_BREAK); break; } switch_ivr_parse_all_events(pt->session); if(switch_channel_has_dtmf(pt->channel)) { switch_channel_dequeue_dtmf(pt->channel, &dtmf); const char * terminators = switch_channel_get_variable(pt->channel, SWITCH_PLAYBACK_TERMINATORS_VARIABLE); if(terminators && !strcasecmp(terminators, "none")) terminators = NULL; switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(pt->session), SWITCH_LOG_DEBUG, "Digit %c\n", dtmf.digit); if(terminators && strchr(terminators, dtmf.digit)) { std::string digit(&dtmf.digit, 0, 1); switch_channel_set_variable(pt->channel, SWITCH_PLAYBACK_TERMINATOR_USED, digit.c_str()); break; } } Which didn't work. I'm asking if anyone has any idea. Any help is appreciated Regards, Paulo R. Panhoto

[Freeswitch-dev] playback in background
by Seven Du 01 Nov '10

01 Nov '10

Hi, I didn't find a way to playback in background in normal dialplan/lua scripts. I know how to use event socket to do async, but I still think it's useful in the following scenario and don't need a socket. - start playback in background - long time query (http or db query) - explicitly stop background playback, or implicitly stop when any further app executes(or when new data writes to the channel) - do other things using the query result Is there any existing solutions? or how hart to make a patch? if I make a patch to achieve that, would it be better to make in mod_commands or should I make a new module? What I'm thinking is to make a BUG in another thread and feed sound data to the channel. Is that the right approach? Thanks. -- Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn

[Freeswitch-dev] How to get Peer Session after Bridge (Originate)
by Achim Stamm 29 Oct '10

29 Oct '10

Hello, I have following problem: I used following code for bridging my current session to multiple Voip Phones in a freeswitch thread (same as bgapi): switch_ivr_originate(session, &peer_session, &cause, "user/60@192.168.1.50,user/61@192.168.1.50", timelimit, NULL, NULL, NULL, NULL, NULL, SOF_NONE,NULL) != SWITCH_STATUS_SUCCESS) Both Phones with number 60 and 61 rings. In a special case I need to know when the peer_session hanged up (channel is not ready any more). I use following code for controling my bridged session (The peer_session) in another Thread: while (!peer_session) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "Session Nebenstelle is NULL ... Wait\n"); Sleep(200); } switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "Session Nebenstelle is created from originate call! \n"); channelNebenstelle = switch_core_session_get_channel(peer_session); while(switch_channel_ready(channel) && switch_channel_ready(channelNebenstelle)) { // Communication : Sleep(200); } switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "Session or Peer Session hangsup!\n"); // doing something special ... My peer_session is NULL, but Communication is possible. Why is my peer_session always NULL ? Is there a better solution (example a core-function) for getting my current connected peer_session ? I have tried switch_ivr_find_bridged_uuid(my_uuid, other_uuid,255 ); and sessionNebenstelle = switch_core_session_locate(other_uuid); ... but I get the session, which have loosed the race. regards Achim Stamm -- Achim Stamm, Dipl.-Inform.

[Freeswitch-dev] Searching for a valid extension.
by Geovani Ricardo Wiedenhoft 29 Oct '10

29 Oct '10

Hello, We are completing development of the mod_khomp endpoint for Khomp boards: - FXS - FXO - E1 - GSM (boards and usb devices) - Passive record - kommuter However, we are constrained in our implementation. We needed to verify that a given set of digits has a valid extension or if can wait for more digits at some points of our code, without making the call. In our implementation for Asterisk (our Khomp channel), we use the functions provided by the Asterisk: ############################## ############################################### ASTERISK: /* \brief Looks for a valid matching extension */ - ast_canmatch_extension /* \brief Looks to see if adding anything to this extension might match something. (exists ^ canmatch) */ - ast_matchmore_extension ############################################################################# Searching for a solution, we implemented within mod_khomp the reading and checking functions of digits and expressions in XML, but our implementation limits us to XML dialplans, which it would not be compatible if the user need the database or other constructions of the dialplan. So, I would like to know what is the possibility of similar functions to be implemented in the core? Thanks :) Geovani Ricardo Wiedenhoft

[Freeswitch-dev] INCOMPATIBLE_DESTINATION after bridging LinkSys3102 and X-Lite
by Achim Stamm 29 Oct '10

29 Oct '10

Hello, I have following problem: An external Call from LinkSys 3102 (Analog phone) is bridged to a X-Lite Phone. X-Lite Phone is ringing and after pickup sometimes I get an error INCOMPATIBLE_DESTINATION (see snippet of logfile). Mostly all works fine, but I can't understand why this error INCOMPATIBLE_DESTINATION sometimes occurs. Is there a solution for avoiding INCOMPATIBLE_DESTINATION or an explanation why this error sometimes occurs? regards Achim Stamm snippet of logfile: 2010-10-25 17:00:58.296875 [DEBUG] sofia.c:4153 Channel sofia/internal/sip:60@192.168.1.114:52111 entering state [ready][200] 2010-10-25 17:00:58.296875 [DEBUG] sofia_glue.c:3585 Audio Codec Compare [PCMA:8:8000:20]/[PCMA:8:8000:20] 2010-10-25 17:00:58.296875 [DEBUG] sofia_glue.c:2354 Set Codec sofia/internal/sip:60@192.168.1.114:52111 PCMA/8000 20 ms 160 samples 2010-10-25 17:00:58.296875 [DEBUG] sofia_glue.c:3518 Set 2833 dtmf send payload to 101 2010-10-25 17:00:58.296875 [DEBUG] sofia_glue.c:2594 AUDIO RTP [sofia/internal/sip:60@192.168.1.114:52111] 192.168.1.114 port 26696 -> 192.168.1.114 port 58588 codec: 8 ms: 20 2010-10-25 17:00:58.296875 [DEBUG] switch_rtp.c:1182 Starting timer [soft] 160 bytes per 20ms 2010-10-25 17:00:58.296875 [DEBUG] sofia_glue.c:2774 Set 2833 dtmf send payload to 101 2010-10-25 17:00:58.296875 [DEBUG] sofia_glue.c:2779 Set 2833 dtmf receive payload to 101 2010-10-25 17:00:58.296875 [DEBUG] switch_channel.c:2324 Send signal sofia/internal/50(a)192.168.1.114 [BREAK] 2010-10-25 17:00:58.296875 [NOTICE] sofia.c:4733 Channel [sofia/internal/sip:60@192.168.1.114:52111] has been answered 2010-10-25 17:00:58.312500 [NOTICE] switch_channel.c:2424 Hangup sofia/internal/50(a)192.168.1.114 [CS_EXECUTE] [INCOMPATIBLE_DESTINATION] 2010-10-25 17:00:58.312500 [INFO] mod_ebv.cpp:1264 leavin ebv_process_call_extern 2010-10-25 17:00:58.312500 [DEBUG] switch_channel.c:2102 Send signal sofia/internal/50(a)192.168.1.114 [KILL] 2010-10-25 17:01:05.375000 [DEBUG] switch_core_state_machine.c:348 (sofia/internal/50(a)192.168.1.114) State EXECUTE going to sleep 2010-10-25 17:01:05.375000 [DEBUG] switch_core_session.c:1021 Send signal sofia/internal/50(a)192.168.1.114 [BREAK] 2010-10-25 17:01:05.375000 [DEBUG] switch_core_state_machine.c:314 (sofia/internal/50(a)192.168.1.114) Running State Change CS_HANGUP 2010-10-25 17:01:05.375000 [DEBUG] switch_ivr_originate.c:3111 sofia/internal/50(a)192.168.1.114 Media Establishment Failed. 2010-10-25 17:01:05.375000 [NOTICE] switch_ivr_originate.c:3113 Hangup sofia/internal/sip:60@192.168.1.114:52111 [CS_CONSUME_MEDIA] [INCOMPATIBLE_DESTINATION] 2010-10-25 17:01:05.375000 [DEBUG] switch_channel.c:2102 Send signal sofia/internal/sip:60@192.168.1.114:52111 [KILL] 2010-10-25 17:01:05.375000 [DEBUG] switch_core_session.c:1021 Send signal sofia/internal/sip:60@192.168.1.114:52111 [BREAK] 2010-10-25 17:01:05.375000 [DEBUG] switch_core_state_machine.c:314 (sofia/internal/sip:60@192.168.1.114:52111) Running State Change CS_HANGUP 2010-10-25 17:01:05.375000 [DEBUG] switch_ivr_originate.c:3228 Originate Resulted in Error Cause: 88 [INCOMPATIBLE_DESTINATION] 2010-10-25 17:01:05.375000 [INFO] mod_ebv.cpp:2218 Originate Failed.
